The influence of a diet on hair growth and vitamins: detailed analysis

Part 1: Fundamentals of Hair Biology and Nutrient Biology

  1. Hair structure: key components and their role

    Hair is a complex structure consisting of two main parts: a hair follicle located in the skin and a hair rod, visible part. The hair rod consists of three layers:

    • Cuticle: The outer protective layer consisting of overlapping scales resembling tiles. It determines the shine and texture of the hair, protecting the inner layers from damage. Damage to the cuticle leads to dryness, brittleness and dullness.

    • Cortex: The main layer of the hair, which is up to 90% of its mass. It contains melanin, which determines the color of the hair, and consists of keratin fibers that provide strength and elasticity.

    • Medulla: The central layer of hair, which is not always the most noticeable in thick hair. Its function is not fully studied, but it is assumed that it promotes thermal insulation and flexibility of the hair.

    Hair follicle is a complex structure in which hair growth occurs. It consists of:

    • Hair onion: The expanded part of the follicle containing matrix cells responsible for the division and the formation of new hair cells.

    • Dermal papilla: A structure rich in blood vessels, providing nutrition of a hair follicle and playing a role in the regulation of hair growth.

    • Sebaceous glands: The glands that produce sebum, which moisturizes the scalp and hair, protecting them from dryness and damage.

    Understanding the structure of the hair is necessary to realize the effect of nutrition on its health and growth. Each hair layer requires certain nutrients to maintain its structure and functioning.

  2. Hair growth cycle: phases and factors of influence

    Hair growth occurs cyclically and consists of three main phases:

    • Anagen (growth phase): The longest phase lasts from 2 to 7 years. During this phase, the cells are active in the hair follicle, which leads to hair growth by about 1 cm per month. The duration of the anagen determines the maximum length of the hair.

    • Katagen (Phase of Transition): A short phase lasting about 2-3 weeks. During this phase, the hair growth ceases, the hair follicle is reduced and the hair is disconnected from the dermal papilla.

    • Telogen (Phase Salm): The resting phase lasts about 3 months. During this phase, the hair remains in the follicle, but does not grow. At the end of the heterogene, the hair falls out, and in its place the new hair in the anagen phase begins to grow.

    Many factors affect the cycle of hair growth, including genetics, hormonal background, age, stress and, of course, nutrition. The deficiency of certain nutrients can reduce the anagen phase, increase the heterogene phase and lead to hair loss.

  3. Key nutrients for hair health: proteins, fats, carbohydrates, vitamins and minerals

    Hair health directly depends on a balanced diet, including all the necessary macro- and trace elements.

    • Squirrels: Hair consists mainly of keratin, protein, so sufficient protein consumption is critical for hair growth and restoration. The lack of protein can lead to thinning, brittleness and hair loss. Good sources of protein: meat, poultry, fish, eggs, dairy products, legumes, nuts and seeds.

    • Fat: Fats are necessary to maintain the health of the scalp and ensure hair elasticity. Especially important are indispensable fatty acids, such as omega-3 and omega-6, which have anti-inflammatory properties and contribute to hair moisture. Good sources of fat: fatty fish (salmon, mackerel, sardines), avocados, olive oil, nuts and seeds.

    • Carbohydrates: Carbohydrates are the main source of energy for the body, including for hair growth. However, it is important to use complex carbohydrates, such as whole grain products, vegetables and fruits, which provide gradual release of energy and do not cause sharp jumps in blood sugar.

    • Vitamins and minerals: Vitamins and minerals play an important role in various processes necessary for hair health, including growth, strengthening and protection against damage. More information about the role of specific vitamins and minerals will be described in the following sections.

Part 2: Vitamins and minerals affecting the growth and health of hair

  1. Vitamin A: The role in the differentiation of cells and the production of sebum

    Vitamin A plays an important role in differentiation of cells, including hair follicle cells. It is necessary for the normal growth and development of hair. In addition, vitamin A contributes to the production of skin fat, which moisturizes the scalp and hair, protecting them from dryness and damage.

    However, excess vitamin A can lead to hair loss. Therefore, it is important to observe moderation in the consumption of products and additives containing vitamin A.

    Good sources of vitamin A: liver, eggs, dairy products, carrots, pumpkin, spinach and other dark green and orange vegetables and fruits.

  2. B vitamins B (Biotin, B12, Folic Acid): Energy exchange and formation of red blood cells

    B vitamins play an important role in the energy exchange and formation of red blood cells, which cause oxygen and nutrients to hair follicles.

    • Biotin (Vitamin B7): One of the most famous hair vitamins. It is involved in the metabolism of amino acids necessary for the formation of keratin. Biotin deficiency can lead to hair loss, fragility of nails and dermatitis. However, the biotin deficiency is relatively rare, and the intake of biotin additives is not always effective if there is no real deficiency.

    • Vitamin B12: It is necessary for the formation of red blood cells and the normal operation of the nervous system. Vitamin B12 deficiency can lead to anemia, which, in turn, can cause hair loss. People who adhere to the vegan or vegetarian diet are especially at risk, since vitamin B12 is mainly found in animal products.

    • Folic acid (vitamin B9): It is necessary for dividing cells and tissue growth, including hair. Folic acid deficiency can lead to a slowdown in hair growth and loss.

    Good sources of group B vitamins: meat, poultry, fish, eggs, dairy products, whole grain products, legumes, nuts, seeds and dark green leafy vegetables.

  3. Vitamin C: antioxidant protection and collagen synthesis

    Vitamin C is a powerful antioxidant that protects the hair follicles from damage caused by free radicals. In addition, vitamin C is necessary for the synthesis of collagen, a protein that strengthens the structure of the hair and scalp.

    Good sources of vitamin C: citrus fruits, berries, kiwi, pepper, broccoli and other fruits and vegetables.

  4. Vitamin D: role in the growth of hair follicles and immune regulation

    Vitamin D plays an important role in the growth of hair follicles and immune regulation. Studies show that vitamin D deficiency can be associated with hair loss, especially with alopecia.

    Vitamin D is synthesized in the skin under the influence of sunlight. However, in the winter months and in regions with low insolation, an additional intake of vitamin D may be required in the form of additives.

    Good sources of vitamin D: fatty fish, eggs, dairy products enriched with vitamin D, and sunlight.

  5. Vitamin E: antioxidant protection and improving blood circulation in the scalp

    Vitamin E is another powerful antioxidant that protects the hair follicles from damage caused by free radicals. In addition, vitamin E can improve blood circulation in the scalp, which contributes to better nutrition of hair follicles.

    Good sources of vitamin E: vegetable oils, nuts, seeds, green leafy vegetables.

  6. Iron: oxygen transport and role in hair growth

    Iron is necessary for the transport of oxygen to the cells of the body, including hair follicles. Iron deficiency can lead to anemia, which, in turn, can cause hair loss. Women are especially at risk during menstruation, pregnant and lactating women.

    Good sources of iron: red meat, poultry, fish, legumes, dark green leafy vegetables. It is important to use products rich in vitamin C, along with products containing iron, since vitamin C improves iron absorption.

  7. Zinc: role in tissue growth and restoration

    Zinc plays an important role in the growth and restoration of fabrics, including hair. He also participates in the regulation of the sebaceous glands. Zinc deficiency can lead to hair loss, dry scalp and dandruff.

    Good sources of zinc: meat, poultry, seafood, nuts, seeds, legumes and whole grains.

  8. Selenium: antioxidant protection and regulation of thyroid hormones

    Selenium is an antioxidant that protects the cells from damage caused by free radicals. In addition, selenium plays an important role in the regulation of thyroid hormones that affect hair growth.

    Good sources of Selena: Brazilian nuts, fish, seafood, meat and eggs.

  9. Magnesium: participation in energy exchange and stress reduction

    Magnesium is involved in energy metabolism, protein and DNA synthesis. It also helps to reduce stress, which can cause hair loss.

    Good sources of magnesium: green leafy vegetables, nuts, seeds, whole grain products and legumes.

  10. Other important minerals: copper, silicon, iodine

    • Copper: It is necessary for the formation of collagen and elastin, which support the structure of the hair and scalp.

    • Silicon: Strengthens the structure of the hair and contributes to their growth.

    • Iodine: It is necessary for the normal functioning of the thyroid gland, which affects hair growth.

Part 3: Dietary strategies to improve hair health

  1. Balanced diet: the key to healthy hair

    The most important principle for hair health is a balanced diet, including all the necessary macro- and microelements. This means the use of various foods rich in proteins, fats, carbohydrates, vitamins and minerals.

    Try to include products from all food groups in your diet:

    • Carrot: Rich Vitamin A.
    • Greek yogurt: It is rich in protein and probiotics, which are useful for the health of the intestines and, therefore, for the health of the hair.

  3. Products that are harmful to the health of hair: what should be avoided

    Some products can negatively affect hair health:

    • Sweet drinks and products: High sugar consumption can lead to inflammation and insulin resistance, which can adversely affect hair growth.
    • Processed products: They contain few nutrients and many harmful additives that can negatively affect hair health.
    • Fast-Food: It contains many saturated and trans fats that can worsen blood circulation in the scalp and make it difficult to enter the nutrients to hair follicles.
    • Alcohol: Excessive drinking of alcohol can lead to a deficiency of nutrients and dehydration, which can adversely affect the health of the hair.
    • Diets with very low calories: They can lead to a deficiency of nutrients and cause hair loss.

  4. The role of hydration: sufficient water consumption for healthy hair

    Hydration plays an important role in maintaining hair health. Water is necessary for the normal functioning of all cells of the body, including cells of hair follicles. The lack of water can lead to dryness, brittleness and dullness of the hair.

    It is recommended to drink at least 8 glasses of water per day.

  5. Food supplements: when and which should be taken

    In most cases, a balanced diet is enough to provide the body with all the necessary nutrients. However, in some cases, you may take food additives:

    • Nutrient deficiency: If you have a diagnosed deficiency of any nutrient, the doctor may prescribe you to take the appropriate additives.
    • Certain health states: Some diseases or conditions, such as pregnancy, lactation or autoimmune diseases, can increase the need for certain nutrients.
    • Vegan or vegetarian diet: People who adhere to a vegan or vegetarian diet may need an additional technique of vitamin B12, iron, zinc and omega-3 fatty acids.

    Before taking any nutritional supplements, it is necessary to consult a doctor or nutritionist.

Part 4: The connection between the diet and various types of hair loss

  1. Telegnum alopecia: connection with the diet and stress

    Telegnum alopecia is a type of hair loss in which a large number of hair follicles prematurely passes into the heterogene phase (peace). This can be caused by various factors, including stress, illness, hormonal changes and a deficiency of nutrients.

    The deficiency of iron, zinc, protein and other nutrients can contribute to the development of telogen alopecia. In addition, sharp weight loss or strict diets can also provoke this condition.

    Treatment of heterogene alopecia includes eliminating the cause of hair loss and providing the body with all the necessary nutrients.

  2. Androgenetic alopecia: the role of diet and hormonal balance

    Androgenetic alopecia (male or female baldness) is a genetically determined state characterized by gradual thinning of the hair. Although genetics plays the main role in the development of this type of hair loss, the diet can also affect hormonal balance and inflammation that can aggravate the situation.

    Some studies show that a diet rich in sugar and processed products can contribute to insulin resistance and an increase in the level of androgens, which can accelerate the development of androgenetic alopecia.

    Diet, rich in antioxidants, anti -inflammatory products and nutrients necessary for the health of hair, can help slow down the progression of androgenetic alopecia.

  3. Focal alopecia: connection with autoimmune diseases and diet

    Focal alopecia is an autoimmune disease in which the immune system attacks the hair follicles, which leads to hair loss in certain areas of the scalp.

    Although the cause of focal alopecia has not been fully studied, some studies show that a diet can play a role in modulating the immune system and inflammation.

    Some people with focal alopecia note an improvement in the condition after excluding certain products from the diet, such as gluten or dairy products. However, additional studies are needed to confirm these results.

  4. Other types of hair loss: the influence of the diet and general recommendations

    There are other types of hair loss, such as trichothylomania (pulled hair) and cicatricial alopecia (hair loss, leading to the formation of scars on the scalp). Although the diet is not the main cause of these conditions, it can play a role in the general health of hair and scalp.

    In general, for all types of hair loss, a balanced diet, rich in proteins, fats, carbohydrates, vitamins and minerals is recommended. It is also important to avoid products that can contribute to inflammation and worsening of the intestinal health.
