The ketogenic diet, commonly known as the keto diet, has become a popular weight-loss method. However, it may come with several side effects, including hair loss. While the keto diet is effective for weight loss, it is restrictive in nature, often leading to nutritional deficiencies that can cause hair thinning or loss. This is especially true during the initial stages of the diet when the body is still adjusting to the new eating pattern. In addition to nutritional deficiencies, other factors such as rapid weight loss, stress, and protein intake can also contribute to hair loss in individuals following a keto diet.

What You'll Learn
Nutritional deficiencies
The keto diet restricts many healthy foods, including grains, beans, fruits, and vegetables. As a result, it may lead to a deficiency in specific nutrients, such as biotin, a B vitamin known for promoting hair growth. Biotin-rich foods, such as fruits and legumes, are often avoided or consumed in small portions on a keto diet. Similarly, the keto diet may not provide adequate protein, which is essential for hair growth. A lack of protein can slow the hair growth cycle, as protein is required to keep hair follicles in the growth phase.
In addition to biotin and protein deficiencies, the keto diet may also lead to a deficiency in the mineral zinc, which is associated with hair loss and very dry skin. Restrictive diets like keto can also disrupt the balance of good bacteria in the gut, affecting digestion and the body's ability to absorb nutrients.
To prevent nutritional deficiencies and hair loss while on a keto diet, it is important to ensure adequate intake of nutrients through diet or supplements. Probiotics can help restore gut bacteria balance, improving digestion and nutrient absorption. Taking a multivitamin can also help cover any potential deficiencies. Consulting a doctor or dietitian before starting a keto diet is recommended to ensure it is appropriate and to address any concerns regarding nutrient deficiencies.

Reduced calorie intake
A ketogenic diet is a very low-calorie diet that restricts carbohydrates, forcing the body to burn fat for energy instead of glucose. This metabolic state is called ketosis. The keto diet has been advertised as a weight-loss wonder, but it is actually a medical diet that comes with serious risks.
The keto diet is associated with a high intake of saturated fats, which can lead to an increase in "bad" LDL cholesterol, linked to heart disease. The diet may also cause nutrient deficiencies, as many nutrient-rich foods such as whole grains, fruits, and vegetables are restricted. This can result in deficiencies of micronutrients like selenium, magnesium, phosphorus, and vitamins B and C.
The keto diet can also lead to reduced calorie intake, as it suppresses appetite and decreases hunger. This is due to changes in appetite hormones such as ghrelin and leptin, as well as the increased production of ketone bodies. Ketone bodies are produced by the liver when the body breaks down fat, and they become the main source of energy for the body and brain during ketosis.
When the body does not receive enough calories, it can affect hair follicle function and impact hair growth and structure. This can lead to hair loss, which is often seen after significant weight loss or extreme diets that do not provide adequate calories or nutrients. Therefore, it is important to ensure that a keto diet is properly planned and monitored to prevent reduced calorie intake and potential hair loss. Consulting with a healthcare professional can help ensure that the diet is followed safely and effectively.

Lack of protein
A ketogenic diet is a low-carb, high-fat diet that can lead to hair loss. This is because the diet is restrictive in nature and may not provide the essential vitamins, minerals, and macronutrients required for hair growth.
Protein is essential for hair growth and repair, and a lack of protein has been found to cause hair loss. On a keto diet, protein is kept to a small percentage, as it is believed that too much protein will stop the process of ketosis. However, this can result in not getting adequate protein, which can slow the hair growth cycle and lead to hair loss.
Eggs, poultry, and meat are high-quality sources of protein that can help promote healthy hair growth. They are also good sources of biotin, which is essential for the production of a hair protein called keratin. Other sources of biotin include liver and salmon. If you are vegan or vegetarian, plant-based protein sources such as nuts and seeds can also help ensure adequate protein intake.
It is important to ensure that your diet includes enough protein to support hair growth. If you are experiencing hair loss, you may need to consider liberalizing your diet or working with a professional to personalize your eating plan to meet your health goals. Taking a multivitamin can also help cover any potential deficiencies and promote healthy hair growth.

Biotin deficiency
Biotin, also known as vitamin B7, is a water-soluble vitamin that is naturally produced in the body by gut bacteria and can also be found in small amounts in certain foods. It is needed to help convert fat, protein, and carbohydrates into energy. Biotin is important for hair health, and a deficiency can lead to hair loss.
A biotin deficiency can cause thinning hair, dry skin, brittle nails, scaly rashes, conjunctivitis, depression, fatigue, numbness and tingling in the arms and legs. It can also lead to dermatitis, a common skin condition thought to be a consequence of impaired fatty acid metabolism. Biotin plays a crucial role in the metabolism of fatty acids, so a deficiency can have a negative impact on skin health.
The ketogenic diet, a low-carbohydrate, high-fat diet, has been found to increase biotin consumption and bioavailability, which can result in exaggerated biotin deficiency in those who are already deficient. Studies in mice have shown that a ketogenic diet can lead to biotin deficiency and subsequent hair loss. In addition, the infant version of the ketogenic diet, known as the "ketone formula," has been found to contain insufficient amounts of biotin, which can lead to biotin deficiency in infants.
However, it is important to note that biotin deficiency is not exclusive to those on a ketogenic diet, and there are other factors that can contribute to low biotin levels. For example, raw egg whites contain a compound called avidin, which binds to biotin and can lead to a deficiency over time if consumed in excess. Inflammatory bowel diseases, such as Crohn's disease, can also impact the body's ability to absorb biotin properly.
To prevent or correct biotin deficiency while on a ketogenic diet, it is recommended to include biotin-rich foods in your diet, such as liver, egg yolks, meat, salmon, avocados, and cauliflower. Additionally, taking a biotin supplement can help ensure adequate intake.

Zinc deficiency
The keto diet is a low-carb, high-fat eating plan that has become popular for its weight loss benefits. However, some people who follow the keto diet experience hair loss within a few months of starting the diet. While hair loss can be caused by various factors, one potential contributor is zinc deficiency.
Zinc is an essential mineral that plays a crucial role in many bodily functions, including thyroid health. The keto diet can lead to nutrient deficiencies, as it restricts certain food groups, such as fruits and carbohydrates. As a result, individuals following the keto diet may not be consuming enough vitamins and minerals, including zinc.
To prevent zinc deficiency and support healthy hair growth, it is important to ensure adequate intake of zinc-rich foods or supplements. However, it is important to note that supplementation should be approached with caution, as excessive zinc intake can also have negative effects. Therefore, individuals experiencing hair loss should consult with a healthcare professional to determine the appropriate course of action.
In summary, while the keto diet may not directly cause hair loss, it can contribute to zinc deficiency, which is a known factor in hair loss. By ensuring adequate zinc intake and maintaining a well-formulated ketogenic diet, individuals can help mitigate hair loss and support overall health.
