Keto And Hair Growth: Does This Diet Help?

The keto diet is a popular weight loss strategy, but it can also lead to hair loss. This is often temporary and occurs within the first six months of starting the diet. The hair loss is likely due to a combination of factors, including reduced calorie intake, rapid weight loss, and nutritional deficiencies. Nutritional deficiencies, such as a lack of protein, vitamins, and minerals, can impact hair growth and health. However, hair loss on keto does not affect everyone, and there are steps that can be taken to mitigate it. These include ensuring adequate nutrient intake, reducing stress levels, and prioritizing sleep.

Calorie deficits

A calorie deficit can also affect the intake of essential vitamins and minerals, which are vital for hair health. For example, a study found that many people who followed a low-calorie diet had nutrient deficiencies after three months. This can include a lack of micronutrients, such as iron, zinc, and vitamin D, all of which are important for hair health.

Additionally, a calorie deficit can lead to reduced protein intake, which is essential for hair growth. Protein provides the body with amino acids, which are necessary for the production of keratin, the main structural protein of hair. Without adequate protein, hair growth may be affected, leading to hair thinning or hair loss.

To prevent hair loss caused by calorie deficits, it is important to ensure a balanced and nutritious diet that includes a variety of healthy proteins, whole grains, fruits, and vegetables. Taking a multivitamin can also help cover any potential deficiencies.

Nutritional deficiencies

Biotin (Vitamin B7)

Biotin is part of the B-complex vitamins and is essential for hair growth. It is present in many animal-based foods, such as eggs and salmon. However, the keto diet may lead to a biotin deficiency as it restricts the consumption of biotin-rich foods like fruits and legumes. A biotin deficiency can cause hair loss, brittle nails, and skin rashes.

Protein

The keto diet recommends moderate protein intake, which may not be sufficient for hair health. Hair follicles require adequate protein, vitamins, and minerals to maintain healthy hair. Insufficient protein intake can disrupt the growth phase of hair follicles, leading to hair loss.

Iron

Iron is crucial for creating hemoglobin, which delivers nutrients and oxygen to cells. During iron deficiency, the body prioritises delivering oxygen to vital organs, and hair follicles are not a priority. This can lead to hair thinning, stunted hair growth, and hair loss, especially in women.

Zinc

Zinc is a trace element vital for tissue growth and repair. It keeps the oil glands around hair follicles functioning optimally. A zinc deficiency is common in people consuming large amounts of cereal grains or those with eating disorders. Zinc deficiency can cause telogen effluvium or brittle hair.

Selenium

Selenium is another trace mineral that supports healthy hair growth. It has antioxidant properties that boost the body's metabolic functioning and help maintain hormonal balance. Selenium also plays a role in producing thyroid hormones, which regulate hair growth. A selenium deficiency can lead to hair loss and serious health issues.

Vitamin D

Vitamin D helps create new, healthy hair follicles, which are essential for hair growth. A vitamin D deficiency has been linked to hair loss, especially in patients with androgenetic alopecia, telogen effluvium, and alopecia areata.

Vitamin E

Vitamin E is an antioxidant that protects the cells in the body from damage. It helps create a protective barrier for the scalp, keeping hair hydrated and healthy. A vitamin E deficiency can lead to oxidative stress in the scalp, which is linked to hair loss.

Folic Acid (Vitamin B9)

Folic acid stimulates cell growth and boosts hair growth. It also helps prevent premature greying by normalising oxygen levels. A folic acid deficiency can cause hair loss.

Other Nutrients

Other nutrients that can impact hair health include essential fatty acids (Omega-3 and Omega-6), vitamin C, and amino acids. Deficiencies in these nutrients can lead to hair loss, thinning, and inflammation.

It is important to note that while the keto diet may lead to nutritional deficiencies, individual responses vary. Consulting a healthcare professional before starting or making significant changes to your diet is always recommended.

Stress

The keto diet is a low-carb, high-fat, and moderate-protein diet. The restrictive nature of the keto diet can lead to hair loss, as it may cause a shock to your body that results in the shutdown of less critical functions, like hair growth. This is especially true if you are not careful with your diet and miss out on important nutrients that fuel hair growth.

Telogen effluvium (TE) is the most common type of hair loss related to stress and dietary changes. It occurs when hair shifts from the growing phase to the resting phase and is often temporary. TE can be triggered by hormonal, autoimmune, or nutritional imbalances, as well as emotional stress and crash diets.

To prevent stress-related hair loss while on the keto diet, it is important to ensure you are getting adequate calories, protein, and key nutrients that contribute to healthy hair. Taking a multivitamin can help cover any potential deficiencies. Aim to get your protein from high-quality sources such as eggs, poultry, and salmon, which are also good sources of biotin.

Additionally, it is crucial to keep stress levels low in other areas of your life while making significant dietary changes. This can help minimize the overall stress your body is experiencing and potentially reduce the risk of stress-related hair loss.

Remember, the keto diet should be carefully planned and monitored to ensure you are getting the proper nutrients and calories your body needs. If you are experiencing hair loss or other side effects, consider consulting a healthcare professional or working with a dietitian to personalize your eating plan.

Weight loss

The keto diet is a popular weight loss strategy, but it can also lead to hair loss. This is because the diet is extremely restrictive, limiting the intake of carbohydrates, proteins, and healthy foods such as grains, beans, fruits, and vegetables. As a result, those on the keto diet may experience a deficiency in nutrients that are essential for hair growth, such as biotin, protein, and iron.

One of the main reasons for hair loss on the keto diet is rapid weight loss. When the body experiences rapid weight loss, it goes into a state of shock, and to conserve energy, it reduces the amount of energy spent on non-vital functions such as hair growth. This can lead to hair thinning or hair falling out.

Another reason for hair loss is a lack of protein in the diet. Protein is essential for hair growth as it provides the building blocks for healthy hair. On the keto diet, protein intake is limited to moderate amounts, and some people may not be getting enough protein in their daily intake.

Additionally, the keto diet can be stressful for the body as it involves a significant reduction in carbohydrate intake, which is the body's main source of energy. This stress can contribute to temporary hair loss.

To prevent hair loss while on the keto diet, it is important to ensure adequate nutrient intake. This includes consuming enough calories, protein, and micronutrients such as biotin and iron. Taking a multivitamin can help cover any potential deficiencies. It is also recommended to focus on slow to moderate weight loss, rather than rapid weight loss, to reduce the risk of hair loss.

While hair loss on the keto diet can be concerning, it is usually temporary and will resolve once the body adjusts to the new diet. However, if hair loss persists, it is important to consult with a doctor to rule out any other underlying health conditions.

Protein intake

Protein is essential for hair growth, as hair follicles rely on the adequate consumption of protein, vitamins, and minerals to maintain a healthy head of hair. The keto diet, which involves a significant reduction in carbohydrate intake, can lead to insufficient protein intake, potentially resulting in hair loss. Therefore, it is crucial to ensure optimal protein intake while following a keto diet to support hair growth and prevent hair loss.

Understanding the Keto Diet

The keto diet, short for the ketogenic diet, is a high-fat, low-carbohydrate diet that aims to shift the body into a state of ketosis. In ketosis, the body primarily uses fat, instead of carbohydrates, as its energy source. While this dietary approach can be effective for weight loss, it can also lead to potential side effects, including hair loss.

The Link Between Protein and Hair Growth

Hair is primarily composed of a protein called keratin. To support the growth and maintenance of hair, the body requires an adequate supply of protein, as well as other essential nutrients. When the body does not receive enough protein, it may prioritise critical functions, such as cell growth and organ function, over hair growth, leading to potential hair loss.

The keto diet's restriction on carbohydrates can make it challenging to consume enough protein. Animal-based foods, such as meat, poultry, and fish, are rich sources of protein. However, the keto diet's emphasis on high-fat foods can lead to reduced consumption of protein-rich options. Additionally, those following a vegan or vegetarian keto diet may find it particularly difficult to meet their protein needs.

Optimising Protein Intake for Hair Growth on Keto

To support hair growth while on the keto diet, it is crucial to focus on consuming sufficient protein from a variety of sources. Here are some strategies to optimise protein intake:

• Include a variety of protein-rich foods in your diet: Aim for high-quality protein sources such as eggs, poultry, red meat, and fish. These foods provide essential amino acids that support hair growth.
• Consider plant-based protein sources: If you follow a vegan or vegetarian keto diet, ensure you incorporate plenty of plant-based proteins like soybean products (tofu, edamame, tempeh), nuts and nut butters, and vegetables (broccoli, spinach, asparagus, Brussels sprouts).
• Calculate your protein needs: Use a keto calculator to determine your specific protein requirements based on your activity level and body composition. Aim for the higher end of the recommended protein intake range to support hair growth and maintain muscle mass.
• Track your protein intake: Utilise a keto-friendly tracking app to monitor your daily protein consumption and ensure you are meeting your protein goals.
• Prioritise micronutrient-rich keto foods: In addition to protein, focus on consuming a variety of micronutrient-rich keto-friendly foods, such as meat, organ meats, fish, shellfish, poultry, eggs, low-carb fruits and vegetables, low-carb nuts and seeds, and high-fat cheese. These foods provide essential vitamins and minerals that support hair growth, in addition to protein.
• Consider supplements: If you find it challenging to meet your protein needs through diet alone, consider adding protein supplements to your routine. Collagen supplements or bone broth can also support hair growth and improve skin and nail health.

In summary, while the keto diet can be effective for weight loss, it is crucial to prioritise adequate protein intake to support hair growth and prevent hair loss. By incorporating a variety of protein-rich foods into your diet and considering supplements, you can optimise your protein intake to support overall health, including the health of your hair.
