Weight Loss and Associated Hair Loss - The Ultimate Guide
Did you know that if you lose weight, you might also lose some hair? While it's not always the case, there is a significant link between weight loss and hair loss.
Losing a large amount of weight quickly can cause temporary hair loss. This type of hair loss is called telogen effluvium. Usually, hair loss from dieting is only temporary and your hair will eventually regrow. However, if you are losing hair in addition to shedding pounds, it could be a sign of another health condition.
In this blog post, we'll explore the causes of hair loss associated with weight loss and offer some tips for prevention. Keep reading to learn more!
What are different types of hair loss?
1. Androgenetic alopecia (male pattern baldness)
2. Alopecia areata (patchy hair loss)
3. Telogen effluvium (temporary hair loss due to stress)
4. Anagen effluvium (hair loss due to chemotherapy)
5. Traction alopecia (hair loss due to tight hairstyles)
6. Trichotillomania (hair loss due to hair pulling)
7. Scarring alopecia (hair loss due to scarring of the scalp)
What are the causes of hair loss?
There are a variety of different conditions that can cause hair loss. Here are some of the most common:
Androgenetic alopecia:
This is the most common type of hair loss, affecting both men and women. Androgenetic alopecia is characterized by a receding hairline and thinning hair on the scalp. In severe cases, men may experience complete baldness.
Androgenetic alopecia is caused by a combination of genetic and hormonal factors. The condition is thought to be passed down from one generation to the next. Additionally, the condition is linked to an excess of the hormone testosterone.
Testosterone levels can be increased by various factors, including stress, poor diet, and certain medical conditions. While there is no cure for androgenetic alopecia, treatments are available that can help to slow the progression of the disease. These treatments include minoxidil ( Rogaine) and finasteride ( Propecia). In some cases, hair transplant surgery may also be an option.
Alopecia areata:
Alopecia areata is a type of hair loss that occurs when the immune system attacks the hair follicles. The exact cause of alopecia areata is unknown. Still, it is believed to be partly hereditary and partly triggered by environmental factors.
The condition can affect people of any age, but it is most common in children and young adults. Alopecia areata usually begins with one or more small, round patches of baldness on the scalp.
The hair loss may then spread to other body parts, such as the face, eyebrows, or beard. In some cases, all of the hair on the scalp and body is lost (Alopecia Universalis).
Alopecia areata is not contagious and does not lead to any permanent hair loss. The hair usually grows back within 12 months, although it may take longer in some cases. There is no cure for alopecia areata, but treatments are available to help promote hair growth.
Telogen effluvium:
Telogen effluvium is a condition that results in thinning hair. It typically occurs after a major stressful event, such as childbirth, surgery, or a severe illness.
The condition is characterized by an increased number of hairs entering the telogen (resting) phase. In the telogen phase, hairs are shed from the scalp. Telogen effluvium usually leads to diffuse hair loss, meaning hair is thinned out all over the scalp rather than in specific areas.
The condition is usually temporary and resolves within 6-9 months. However, in some cases, telogen effluvium can be a chronic condition that lasts for years.
Treatment for telogen effluvium typically involves managing stress levels and addressing any underlying medical conditions. In severe cases, certain medications may be used to promote hair growth.
Anagen effluvium:
Anagen effluvium is a type of hair loss typically caused by chemotherapy. Chemotherapy drugs damage the cells that are responsible for hair growth, causing the hair to fall out.
Anagen effluvium is different from alopecia, which is another type of hair loss that can be caused by chemotherapy. The hair falls out quickly and evenly over the scalp with anagen effluvium.
In contrast, with alopecia, the hair falls out in patches. Anagen effluvium is also different from telogen effluvium, which is another type of hair loss that can be caused by chemotherapy. With telogen effluvium, the hair does not fall out evenly over the entire scalp. Instead, it falls out in patches.
Anagen effluvium is the most common type of hair loss caused by chemotherapy, affecting both men and women. There is no cure for anagen effluvium. However, the hair usually grows back after chemotherapy is finished.
Traction alopecia:
Traction alopecia is a form of alopecia or gradual hair loss caused by repeated pulling or tension on the hair follicles. This can occur from tight hairstyles such as braids, ponytails, cornrows, hair extensions, tight headbands, and other hair-styling tools and products.
Traction alopecia usually develops over time, and the first signs may be small areas of baldness or thinning hair. If the condition is left untreated, it can eventually lead to permanent hair loss.
Treatment for traction alopecia typically involves avoiding hairstyles that pull on the hair and allowing the affected follicles to rest and heal. In some cases, medical interventions may be necessary to prevent further damage.
Trichotillomania:
Trichotillomania is an impulse control disorder that causes people to pull out their hair. It can affect men, women, and children of all ages and can lead to significant hair loss.
While the exact cause of trichotillomania is unknown, it is believed to be related to brain chemistry or genetic problems. The condition is often associated with anxiety, depression, and stress and may be triggered by certain events or experiences.
Treatment for trichotillomania typically involves a combination of counseling and medication. With proper treatment, most people with trichotillomania can significantly reduce their hair-pulling behavior.
Scarring alopecia:
Scarring alopecia is a type of hair loss that occurs when the hair follicle is destroyed, and the skin is replaced with scar tissue. It can be caused by various factors, including infections, inflammatory disorders, and trauma.
There are several types of scarring alopecia, each with its symptoms and treatment options. The most common type, cicatricial alopecia, typically affects the scalp and can lead to permanent hair loss.
Scarring alopecia is often challenging to treat and may require a combination of medication and surgery. In some cases, the hair may eventually regrow on its own. However, it is vital to seek medical treatment as soon as possible to prevent permanent damage to the hair follicles.
What causes weight loss and hair loss at the same time?
There are many potential causes of weight loss and hair loss simultaneously. Here is a list of 13 common causes:
Thyroid problems:
You may experience sudden weight loss and falling hair simultaneously with thyroid problems. This is because the thyroid gland plays a vital role in regulating metabolism and protein production.
When metabolism slows down, it can lead to weight loss, as well as hair loss due to the lack of nutrients being delivered to the scalp. Also, because the thyroid helps to regulate the production of proteins, it can lead to a decrease in hair-building proteins such as keratin when it isn't functioning properly.
While thyroid problems can cause weight loss and hair loss, it is essential to note that there are other potential causes as well. If you are experiencing sudden or severe weight loss or hair loss, you must speak to your doctor to rule out other possible causes.
Autoimmune diseases:
There are a variety of autoimmune diseases that can cause rapid weight loss and hair loss. One of the most common is alopecia areata, an autoimmune disease affecting hair follicles.
When someone has alopecia areata, their body's immune system mistakenly attacks the hair follicles, causing them to fall out. This can happen all over the body or be confined to one area.
Other autoimmune diseases that can cause hair loss include lupus and psoriasis. Autoimmune diseases can also cause weight loss because the body's immune system attacks healthy cells. This can lead to a decrease in appetite and difficulty absorbing nutrients.
In some cases, people with autoimmune diseases may also experience fatigue, making it challenging to maintain a healthy weight. While there is no cure for autoimmune diseases, treatments can help manage the symptoms and improve quality of life.
Nutritional deficiencies:
There are a few reasons why nutritional deficiencies can cause rapid weight loss and hair loss at the same time. First, when the body is not getting enough nutrients, it will start to break down muscle tissue for energy, and this can lead to weight loss and a decrease in muscle mass.
In addition, the body will also start to break down hair follicles to conserve energy. This can lead to thinning hair and eventually hair loss. Finally, nutritional deficiencies can also cause problems with the production of new hair cells.
This can lead to a slower rate of hair regrowth, which can further contribute to hair loss. In summary, nutritional deficiencies can have several adverse effects on the body, including weight loss and hair loss.
Hair loss can be a sign of nutritional deficiencies, such as iron deficiency or vitamin D deficiency.
Stress:
When stressed, your body goes into "fight or flight" mode. This response is meant to help you deal with a perceived threat by preparing your body to either fight or run away.
As part of this response, your body diverts blood away from your digestive system and towards your muscles. This can lead to weight loss, as your body cannot process food efficiently.
In addition, emotional stress also causes your hair follicles to go into a resting state. This can lead to hair loss as new hair growth is halted. While the "fight or flight" response is meant to be helpful in the short term, long-term exposure to stress can have severe effects on your health.
If you are losing weight and hair due to stress, it is vital to seek help from a medical professional to manage your stress levels and protect your health.
Certain medications:
It can be alarming when you simultaneously experience unexplained weight loss and hair loss. However, in some cases, these symptoms may be caused by medication.
Certain medications, such as those used to treat diabetes and thyroid conditions, can cause hair loss and weight loss as side effects. In other cases, hair loss and weight loss may occur due to the body's reduced ability to absorb nutrients and receive adequate calories.
Medications that interfere with nutrient absorption, such as those used to treat Crohn's disease and celiac disease, can also lead to weight loss and hair loss. In addition, certain medications can interfere with the body's ability to produce keratin. This protein is essential for healthy hair growth.
Suppose you are taking medication and experiencing these symptoms. In that case, you must speak with your doctor to determine whether the medication is the cause. In most cases, these side effects are temporary and can be managed with changes in dosage or diet. However, if the symptoms persist, your doctor may recommend discontinuing the medication.
Skin conditions:
It's not uncommon for people with skin conditions to simultaneously experience hair loss and weight loss. While the two conditions may seem unrelated, they can be closely linked.
Skin conditions can cause inflammation throughout the body, leading to metabolism and nutrient absorption disruptions. In turn, this can lead to weight loss and Hair loss.
In addition, skin conditions can cause changes in hormone levels such as testosterone and estrogen. These changes can also interfere with hair growth, leading to hair loss. Finally, skin conditions can also cause stress and anxiety, further contributing to hair loss.
If you are experiencing these symptoms, you must speak with a medical professional to determine whether a skin condition is a cause.
Fungal infections:
A fungal infection can cause weight loss and hair loss simultaneously for several reasons. For one, the fungus can interfere with your body's ability to absorb food nutrients, leading to weight loss.
In addition, the fungus can affect your hair follicles, leading to thinning hair or hair loss. Finally, the fungus can also cause inflammation throughout your body, leading to weight loss.
While these are all common effects of a fungal infection, it is essential to speak with your doctor if you are experiencing any of these symptoms so that you can get proper treatment. Left untreated, a fungal infection can cause serious health complications.
Genetic conditions:
There are a variety of genetic conditions that can cause both weight loss and hair loss. One common condition is alopecia areata, an autoimmune disorder that causes patchy hair loss. This condition can also lead to weight loss due to the malabsorption of nutrients.
Other conditions that can cause weight loss and hair loss include trichotillomania, an irresistible urge to pull out one's hair, and telogen effluvium, a shedding of the hair that occurs when the growth cycle is interrupted.
In both cases, the hair loss can eventually lead to weight loss as the body fails to get the nutrients it needs. Thus, it is vital to seek medical help if you experience both weight loss and hair loss, as this may be a sign of a severe underlying condition.
Aging:
As we age, our metabolism slows down, and we lose muscle mass. At the same time, our hair follicles gradually shrink, causing our hair to thin out.
While it is common to lose some hair as we age, both men and women can experience accelerated hair loss due to aging. This is often accompanied by weight loss, as the body becomes less able to absorb and process nutrients. In some cases, hair loss and weight loss may be due to an underlying medical condition, such as an autoimmune disorder or thyroid disease.
However, there are some things you can do to help slow down the process. Eating a healthy diet and getting regular exercise can help to boost your metabolism and maintain muscle mass.
Additionally, using products specifically designed for thinning hair can help to fortify your follicles and prevent further hair loss. With a little effort, you can help to keep your body and hair looking young and healthy well into your golden years.
Cancer:
There are a few reasons why cancer can cause weight loss and hair loss simultaneously. One of the most common is cancer cells can metastasize or spread to other body parts. This can lead to cachexia, which is a form of malnutrition that is characterized by weight loss, muscle wasting, and fatigue.
Cancer cells can also directly interfere with the body's ability to absorb nutrients, leading to weight loss. Also, some cancer treatments, such as chemotherapy, can cause hair loss by damaging the hair follicles.
While hair loss is typically not permanent, it can be a side effect of cancer that causes significant emotional distress. Fortunately, there are treatments available that can help to prevent or lessen hair loss. If you are experiencing hair loss due to cancer, talk to your doctor about your options.
Anemia:
Anemia is when the body does not have enough healthy red blood cells. Red blood cells carry oxygen to the body's tissues.
There are many different types of anemia, each with its cause. Some types of anemia can be temporary and easily treated. In contrast, others may be more serious and require more aggressive treatment.
Regardless of the type, anemia can cause a variety of symptoms, including fatigue, shortness of breath, and pale skin. One of the more common symptoms of anemia is weight loss. This can occur because the body's tissues are not receiving enough oxygen, causing them to break down muscles to function.
Additionally, anemia can cause hair loss. This is usually because the body cannot produce enough keratin, a protein that helps to form hair. In severe cases, anemia can be life-threatening. If you think you may have anemia, it is vital to see a doctor receive a proper diagnosis and treatment.
Scalp infections:
Scalp infections are a common cause of weight loss and hair loss. The most common type of scalp infection is seborrheic dermatitis, which is caused by an overgrowth of the yeast that naturally occurs on the skin. This yeast can cause inflammation and itching, as well as hair loss.
Other types of scalp infections include folliculitis, a condition of the hair follicles, and ringworm. This fungus can affect the scalp and other parts of the body.
Scalp infections can also be caused by bacteria, such as staphylococcus and streptococcus. In addition, scalp infections can affect the appetite, leading to rapid weight loss.
Treatment for scalp infections typically includes antimicrobial shampoo or cream and oral or topical antifungal medication. In severe cases, hair transplantation may be required. While scalp infections can be quite distressing, it is essential to remember that they are usually easily treated and do not cause permanent hair loss.
Contact dermatitis:
There are a few different ways in which contact dermatitis can lead to weight loss and hair loss. One is through the inflammation of the skin caused by the condition. This can lead to reduced appetite and difficulty absorbing nutrients, which can lead to weight loss.
In addition, contact dermatitis can cause an increase in the production of stress hormones, which can lead to hair loss. Finally, the itching and scratching associated with contact dermatitis can disrupt sleep, leading to fatigue and further weight loss.
While contact dermatitis is not usually a serious condition, it can significantly impact the quality of life. Suppose you are experiencing unexplained weight loss or hair loss. In that case, it is vital to speak to a doctor to rule out other potential causes.
How does weight loss cause hair loss?
Weight loss can cause hair loss for a variety of reasons. Here is a list of 12 possible causes of weight loss and hair loss:
Hormonal imbalances:
Hormonal imbalances are one of the most common causes of weight loss and hair loss. When the body's hormones are out of balance, it can affect various functions, including metabolism, appetite, and hair growth.
Several studies showed that there is a link between weight loss, hair loss, and hormonal imbalances, such as thyroid disorders, polycystic ovary syndrome (PCOS), and adrenal gland disorders. Treatment for hormonal imbalances usually involves medication to correct the imbalance.
Conditions like pregnancy and menopause can also cause hormone changes. These changes are usually temporary and will resolve on their own. Suppose you are experiencing unexplained weight loss or hair loss. In that case, it is vital to speak to a doctor to rule out hormonal imbalances.
Nutritional deficiencies:
Nutritional deficiencies are another common cause of weight loss and hair loss. When the body does not get enough nutrients, it can lead to various health problems, including hair loss.
Iron deficiency is one of the most common nutritional deficiencies and is a significant cause of hair loss. Other nutrients vital for healthy hair growth include zinc, biotin, and vitamin D. A lack of these nutrients can lead to diffuse hair loss, which is when hair falls all over the scalp.
Vitamin D deficiency is a common cause of weight loss, leading to decreased appetite and fatigue. Nutrient deficiencies can be caused by various factors, including poor diet, malabsorption disorders, and chronic illnesses.
Treatment for nutritional deficiencies typically involves taking supplements or eating healthy foods rich in deficient nutrients.
Eating a balanced diet is the best way to ensure you get all the nutrients you need. However, suppose you are experiencing severe hair loss. In that case, you may need to take supplements or eat foods fortified with these nutrients.
Autoimmune disorders:
Autoimmune disorders are another possible cause of weight loss and hair loss. When the body's immune system attacks healthy cells, it can lead to a variety of symptoms, including hair loss.
Alopecia areata is an autoimmune disorder that causes patchy hair loss. This hair loss is often temporary but can lead to permanent hair loss if the condition is not treated. Other autoimmune disorders that can cause weight loss and hair loss include lupus, Hashimoto's disease, and Crohn's disease.
Autoimmune disorders can be challenging to diagnose and treat. Suppose you are experiencing unexplained weight loss or hair loss. In that case, you must consult a doctor to rule out other potential causes.
Medications:
Certain medications can cause weight loss and hair loss as side effects. Some of the most common medications that can cause these side effects to include chemotherapy drugs, beta-blockers, and antidepressants.
Suppose you take any medications and experience unexplained weight loss or hair loss. In that case, it is vital to speak to your doctor to rule out other potential causes.
Stress:
Stress is another common cause of weight loss and hair loss. When the body is under stress, it can lead to various health problems, including rapid weight loss.
When the body is under stress, the body cannot properly absorb nutrients, leading to nutrient deficiencies. Nutrient deficiencies can cause losing weight, hair falling, and a variety of other health problems.
In addition, psychological stress can cause your hair follicles to go into a resting phase, which can lead to diffuse hair loss. Suppose you are experiencing unexplained weight loss or hair loss. In that case, it is vital to speak to a doctor to rule out other potential causes.
Thyroid problems:
Thyroid problems are another common cause of weight loss and hair loss. The thyroid is a gland that helps regulate the body's metabolism. When the thyroid is not functioning properly, it can lead to a variety of health problems, including weight loss and hair loss.
Hypothyroidism is the most common type of thyroid disorder and can cause diffuse hair loss. Hashimoto's disease is another type of thyroid disorder that can cause diffuse hair loss.
Thyroid disorders can be challenging to diagnose and treat. If you are experiencing unexplained weight loss or hair loss, you must speak to a doctor to rule out other potential causes.
Celiac disease:
Celiac disease is another possible cause of weight loss and hair loss. Celiac disease is a condition that causes damage to the small intestine when certain foods are eaten.
This damage can lead to nutrient deficiencies, which can cause rapid weight loss and hair loss because the body cannot absorb nutrients properly.
Hair loss after weight loss can also be a symptom of celiac disease. If you are experiencing unexplained weight loss or hair loss, you must speak to a doctor to rule out other potential causes.
Celiac disease can be challenging to diagnose and treat. However, following a gluten-free diet is the best way to manage the condition and prevent further damage to the intestine.
Eating disorders:
Eating disorders are another possible cause of weight loss resulting in hair loss. Eating disorders such as anorexia nervosa and bulimia nervosa can lead to rapid weight loss, resulting in hair loss.
Nutrient deficiencies are common in people with eating disorders, which can lead to a variety of health problems, including hair loss.
Eating disorders are severe mental health conditions that require treatment. The best way to treat an eating disorder is with professional help from a doctor or therapist.
Anemia:
Anemia is a condition that can cause a variety of symptoms, including weight loss and hair loss. The most common cause of anemia is iron deficiency, which can occur for various reasons, including blood loss, poor absorption of iron, or inadequate iron intake.
When iron levels are low, the body cannot produce enough hemoglobin, the protein that carries oxygen in the blood. As a result, cells and tissues do not receive the oxygen they need to function properly. Iron deficiency anemia can lead to fatigue, weakness, and weight loss.
In addition, low iron levels can affect the production of keratin. This protein helps to make hair strong and healthy. As a result, people with anemia may experience thinning hair or excessive hair shedding. If you are experiencing these symptoms, it is crucial to see a doctor so that you can receive treatment.
Cancer:
Cancer cells have a high metabolism rate and burn more energy than healthy cells. As a result, cancer patients often experience weight loss, as their bodies are unable to keep up with the energy demands of the cancer cells.
Hair loss is another common cancer symptom, and several factors can cause it. Cancer treatment, such as chemotherapy and radiation therapy, can damage the hair follicles and prevent new hair from growing.
In addition, the high rate of metabolism associated with cancer can lead to a deficiency in nutrients, which can also cause hair loss. Cancer cells may sometimes attack the hair follicles, leading to hair loss.
While cancer can cause both weight loss and hair loss, it is essential to remember that these symptoms can also be caused by other factors, such as stress or malnutrition. Suppose you are experiencing either of these symptoms. In that case, it is crucial to speak to your doctor so that they can rule out any other potential causes.
Weight loss surgery:
Weight loss surgery, such as gastric bypass surgery, can lead to hair loss. The surgery can cause a nutrient deficiency, leading to various health problems, including hair loss.
In addition, weight loss surgery can cause stress to the body and lead to hair loss. Speaking to your doctor about the potential risks of hair loss before undergoing any weight loss surgery is essential.
Laparoscopic sleeve gastrectomy is a type of weight loss surgery that has been linked to an increased risk of hair loss. The surgery can cause a nutrient deficiency, leading to various health problems, including hair loss.
Hair loss after weight loss surgery is usually temporary. It will typically grow back once your body has adjusted to the surgery.
Restrictive diet:
Restrictive dieting can also lead to hair loss. A restrictive diet can cause nutrient deficiencies, leading to various health problems, including hair loss.
When you follow crash diets or other restrictive diets, you may lose a lot of weight quickly. However, this weight loss is usually not sustainable, and you will likely regain the weight once you stop dieting.
Crash diets affect hair growth by causing temporary hair loss called telogen effluvium. This is a condition that causes the hair follicles to enter a resting phase and stop growing new hair.
Once you resume eating a normal diet, the hair follicles will typically start growing new hair within a few months. However, it can take up to a year for the hair to return to its pre-diet thickness.
In addition, restrictive dieting can lead to stress and trigger hair loss. If you are considering crash diets, it is essential to speak to your doctor first so that they can check for any potential risks and give you a treatment plan.
What to do about hair loss caused by weight loss?
There are many possible causes of hair loss, including genetics, illness, and stress. However, one of the most common causes of hair loss is sudden weight loss.
When you lose a significant amount of weight, your body enters into a " starvation mode." To conserve energy, your body begins to shut down non-essential functions, such as hair growth.
As a result, you may notice that your hair is thinning or falling out. If you are concerned about hair loss caused by weight loss, there are several things you can do.
First, try to lose weight instead of crash dieting gradually. This will give your body time to adjust and may help to prevent hair loss.
Secondly, ensure you get enough protein and other vitamins and minerals. This will help to keep your hair healthy and prevent further breakage.
Biotin supplements are also helpful for preventing hair loss. Biotin is a water-soluble vitamin that helps support skin, nails, and hair health. In addition, amino acids are also crucial for hair health. Amino acids are protein's building blocks and can help promote hair growth.
Try to reduce the amount of stress in your life. Stress can trigger hair loss, so finding ways to relax and manage your stress levels is crucial.
Finally, consider using a mild shampoo or conditioner for people with thinning hair. These products can help to make your hair look fuller and healthier.
If you are still concerned about hair loss, talk to your doctor or a dermatologist. They can provide further guidance and recommendations based on your situation.
Does hair loss from weight loss grow back?
Many people experience hair loss when they lose weight. While it can be alarming, it is usually not a cause for concern. In most cases, the hair will grow back once the person has stabilized their weight and followed a balanced diet.
However, there are some exceptions. People experiencing severe or sudden weight loss may have a more serious form of hair loss called telogen effluvium. This hair loss is often temporary and can be caused by stress or hormonal changes.
However, it can also be a sign of an underlying health condition, so it is vital to see a doctor if you experience sudden or severe hair loss.
In rare cases, hair loss can be permanent. This is most likely to occur in people who experience severe and prolonged weight loss, such as those with eating disorders. If you are concerned about hair loss, talk to your doctor, and they can help to determine the cause and recommend treatment options.
Final Thoughts
Losing weight can be a great way to improve your health and appearance. However, it is vital to know that sudden or severe weight loss can cause hair loss.
If you are concerned about hair loss, talk to your doctor, and they can help to determine the cause and recommend treatment options. In most cases, the hair will grow back once the person has stabilized their weight and followed a balanced diet.
