Keto Diet: Biotin and Hair Health
Unveiling the Connection
The ketogenic, often referred to as keto, diet is a high-fat, low-carbohydrate eating plan that has gained popularity for its potential benefits in weight loss and metabolic health. However, individuals adopting this diet sometimes report side effects, including changes in hair health. The alterations in nutritional intake that accompany the transition to a ketogenic diet can have an impact on hair growth, as the body adjusts to different sources of energy.
Biotin, also known as vitamin B7, plays a crucial role in maintaining healthy hair, skin, and nails. This water-soluble vitamin is essential for the body's keratin infrastructure—a protein that forms the structure of hair. While biotin deficiencies are relatively rare, the change in food choices on the keto diet could potentially affect the levels of biotin and the nutrients that support hair health.
Observations suggest that some individuals may experience hair thinning or loss when starting the keto diet, which could be attributed to factors such as caloric restriction, initial rapid weight loss, and potential nutrient deficiencies. Ensuring an adequate intake of biotin may help support hair health for those on a ketogenic diet. However, the connection between the keto diet, biotin, and hair health requires a deeper look to understand how these factors interact and what strategies can help maintain hair vitality within this lifestyle.
Understanding Biotin and Its Role in the Body
Biotin, a water-soluble B vitamin, is essential for the normal functioning of the body, particularly in supporting metabolic processes and the health of hair, skin, and nails.
Biotin's Function and Sources
Biotin acts as a crucial coenzyme for several enzymes involved in the metabolism of fats, carbohydrates, and proteins. It is necessary for the conversion of food into energy, playing a significant role in maintaining a steady metabolic rate. The body also requires biotin for the production of keratin, a protein that is fundamental for hair growth and health.
Dietary Sources of Biotin:
Egg yolks
Nuts and seeds
Liver and other meats
Dairy products
Some vegetables such as spinach and broccoli
In the context of a keto diet, where carbohydrate intake is drastically reduced to promote ketosis, biotin's role in metabolizing the increased intake of fats becomes particularly important.
The Impact of Biotin on Hair Growth
Biotin contributes significantly to cell growth, which in turn affects hair growth and health. Hair is composed of keratin, a form of protein that relies on biotin for its production.
Hair Growth Factors:
Biotin supports the hair's keratin infrastructure.
Biotin deficiencies can lead to hair thinning and hair loss.
Adequate biotin levels contribute to the strength and resilience of hair shafts.
For individuals on a keto diet, ensuring sufficient biotin intake is key to maintaining healthy hair despite the dietary restrictions, as it aids in combating potential hair issues related to changes in metabolism.
Basics of the Keto Diet
The keto diet revolves around a high-fat, low-carb regimen that aims to shift the body's primary energy source from carbohydrates to fats.
Principles of Ketogenic Dieting
The ketogenic diet, commonly known as the keto diet, is predicated on a nutritional plan that prioritizes fats and minimizes carbohydrates. The primary goal is to induce the body into a metabolic state known as ketosis, where fat, rather than glucose derived from carbohydrates, is the main source of energy. This approach typically requires that roughly 70-80% of daily caloric intake come from fat, 5-10% from carbohydrates, and the remainder from protein.
Ketosis and Energy Production
When carbohydrate consumption is drastically reduced, the body depletes its glucose reserves and begins to search for an alternative energy source. It enters a state called ketosis, wherein the liver converts fat into fatty acids and ketone bodies. Those ketones then become the main energy source for the body and brain. Achieving ketosis is a clear indicator that the body has switched from carb utilization to fat-burning for energy production.
Nutritional Considerations on Keto
While adhering to a ketogenic diet, individuals must pay meticulous attention to their intake of macronutrients and essential vitamins and minerals to maintain overall health and prevent hair loss.
Adequate Protein Intake
Protein is fundamental for hair health, and a moderate intake is important on a ketogenic diet. It supplies amino acids necessary for keratin production, vital for hair strength. Sources like chicken, beef, fish, and eggs should be regularly included. An intake of 1.0 to 1.5 grams of protein per kilogram of body weight may be advisable for most individuals.
Vitamin and Mineral Needs
The body demands a wide spectrum of vitamins and minerals to function properly. On keto, one must ensure they receive:
Electrolytes: Increased intake of potassium, sodium, and magnesium can be necessary to counterbalance electrolyte loss from reduced carbohydrate consumption.
Vitamin E: An antioxidant that can protect cells, including hair follicles, found in nuts and seeds.
B Vitamins: Particularly biotin, for maintaining healthy skin, nails, and hair, among other functions.
Essential minerals like iron and zinc, which support hair growth and repair, are found in meats, seeds, and nuts.
Fat-soluble vitamins such as vitamin A, vitamin D, and vitamin K, which are found in high-fat keto-friendly foods.
Balancing Macronutrients and Calories
For optimal health and hair maintenance, understanding and balancing fats, protein, and a small amount of carbohydrates is key. Consuming sufficient calories to meet metabolic needs without excessive restriction supports both energy levels and hair growth. The typical macronutrient distribution on a ketogenic diet might look like this:
Fats: 70-80% of daily calories
Protein: 15-20% of daily calories
Carbohydrates: 5-10% of daily calories
Monitoring calorie intake ensures that the body does not go into a state of calorie deficit which may lead to hair loss.
The Relationship Between Hair Health and Diet
Diet plays a significant role in maintaining hair health, with nutrient deficiencies often leading to hair loss and thinning hair. The ketogenic diet, in particular, has been associated with hair loss, warranting a closer examination of its impact on hair health.

Nutrient deficiencies can cause hair to become weak, brittle, and prone to shedding. Each of the following nutrients is critical for hair health:
Biotin (Vitamin B7): Biotin's role in keratin production makes it a vital nutrient for hair strength and growth. A deficiency in biotin can lead to hair thinning and loss.
Iron: Essential for the production of hemoglobin, iron deficiency can reduce oxygen supply to hair follicles, causing hair loss.
Zinc: Zinc plays an important part in hair tissue growth and repair. Without sufficient zinc, one might experience hair shedding.
Protein: Hair is primarily made of protein; a low intake can result in weakened hair strands and loss.
Fatty acids: Omega-3 and omega-6 fatty acids are crucial for healthy hair. Their lack can lead to a dry scalp and dull hair.
Restricted diets, especially those that cut out multiple food groups, may lead to inadequate intake of these essential nutrients.
Keto Diet and Hair Loss: Understanding the Connection
The ketogenic diet is a high-fat, moderate-protein, and low-carbohydrate regimen. Keto hair loss can occur due to several factors linked to this specific diet:
Calorie Restriction: Rapid weight loss from a significant caloric deficit can shift the body's focus from non-essential functions, like hair growth, to more vital ones.
Biotin Deficiency: Since the keto diet restricts certain foods, individuals may not get enough biotin, exacerbating the risk of hair loss.
Initial Phases of Keto: During the early stages of the diet, the body experiences stress from drastic dietary changes, which can lead to increased hair shedding.
By understanding the dietary elements that are essential for hair health and identifying how the keto diet alters these elements, individuals can take steps to counteract potential negative effects on hair health.

Medical and Genetic Factors in Hair Health
Healthy hair growth is influenced by a complex interplay of medical and genetic factors. It is essential to understand the stages of hair growth and how medications and underlying conditions can impact hair health.
Understanding Hair Growth Phases
Hair development undergoes three primary phases: the anagen phase, catagen phase, and telogen phase. During the anagen phase, hair follicles are actively growing, which can last for years. This phase is crucial as it determines the length of hair. The catagen phase is a transitional period that lasts for a few weeks, where hair growth slows and the hair follicle shrinks. Lastly, the telogen phase is a resting phase that culminates in hair shedding.
Alopecia, or hair loss, can occur when these phases are disrupted. Telogen effluvium, for example, is a condition where an increased number of hairs enter the telogen phase, leading to noticeable thinning. In some genetic forms of alopecia, hair follicles prematurely enter the telogen phase, resulting in hair thinning and loss.
Medications and Conditions Affecting Hair
Various medications and health conditions can interfere with normal hair growth. Medicinal compounds, particularly those used for chemotherapy, are known to cause temporary to permanent hair loss by abruptly halting cell division in hair follicles. Other drugs, such as antiepileptics and antibiotics, may also contribute to hair thinning.
Certain medical conditions, such as hormonal imbalances or autoimmune diseases where the body attacks hair follicles, can lead to hair loss. Furthermore, diet changes like the induction of ketosis on a ketogenic diet can stress the body. A study has linked this diet-related stress to telogen effluvium, exacerbating hair loss. During ketosis, the body may prioritize essential functions over hair growth, making the intake of adequate nutrients, including biotin, paramount for maintaining hair health.
