How vitamins affect hair growth: a comprehensive guide
Part 1: fundamental principles of hair growth and nutrition
Hair growth is a complex biological process that depends on genetics, hormonal balance and, importantly, on the receipt of the necessary nutrients. The hair follicle located in the dermis is a living microscopic factory producing the hair rod. This process includes cellular division, differentiation and keratinization – the transformation of cells into solid protein keratin, which is the main mass of the hair. The lack of key vitamins and minerals can directly affect these processes, leading to a slowdown in growth, thinning of hair, brittleness and even loss.
Hair growth phases:
- Anagen (growth phase): This is an active phase when the cells of the hair follicle are actively divided, and the hair grows. The duration of this phase determines the maximum hair length. Usually lasts from 2 to 7 years.
- Katagen (transition phase): This is a short transition period lasting about 2-3 weeks, when hair growth stops, and the follicle is reduced.
- Telogen (Phase Salm): The hair follicle is at rest, and the old hair remains in the follicle until the new hair begins to grow and pushes it. This phase lasts about 3 months.
- Exogen (falling phase): This is the phase when the hair falls out. Normally, about 50-100 hair falls daily.
It is important to understand that not all hair loss is associated with a deficiency of vitamins. Other factors, such as stress, hormonal changes (pregnancy, menopause), thyroid diseases, autoimmune diseases and some drugs can also affect hair growth. However, optimizing the consumption of vitamins and minerals can significantly improve hair health and maintain their normal growth.
Part 2: B vitamins: the key to a healthy hair growth
B vitamins play the central role in the metabolism of energy and the functioning of the nervous system. They are also important for the health of the skin, hair and nails. The disadvantage of any of the vitamins of group B can lead to problems with the hair.
- Biotin (Vitamin B7): Biotin, perhaps the most famous vitamin for hair growth. It is necessary for the metabolism of fats, carbohydrates and proteins, which are building blocks for healthy hair. Biotin helps strengthen hair, reduce brittleness and stimulate growth. Although the Biotin deficiency is relatively rare, it can manifest itself in the form of thinning of hair and dermatitis. Products rich in biotin: eggs (especially yolk), nuts (almonds, walnuts), seeds, avocados, salmon, sweet potatoes. It is important to note that excessive use of raw eggs can prevent the assimilation of biotin.
- Niacin (Vitamin B3): Niacin improves blood circulation, including in the scalp, which contributes to the delivery of oxygen and nutrients to hair follicles. This helps stimulate hair growth and improves their overall health. Niacin deficiency can lead to hair loss and dry scalp. Products rich in niacin: meat (especially bird and fish), mushrooms, peanuts, green vegetables.
- Pantotenic acid (vitamin B5): Pantotenic acid plays an important role in the metabolism of fats and carbohydrates, and also promotes hair growth. It helps to strengthen the hair follicles and reduce hair loss. Pantotenic acid can also help improve the texture of the hair and make it more shiny. Products rich in pantothenic acid: eggs, meat, milk, avocados, mushrooms, broccoli.
- Vitamin B12 (cobalamin): Vitamin B12 is necessary for the formation of red blood cells, which transfer oxygen to all cells of the body, including hair follicles. Vitamin B12 deficiency can lead to anemia, fatigue and hair loss. Vitamin B12 is mainly contained in animal products, such as meat, fish, eggs and dairy products. Vegetarians and vegans are recommended to take additives with vitamin B12.
- Folic acid (vitamin B9): Folic acid is necessary for cell division and growth, which makes it important for hair growth. It helps to form healthy red blood cells and transfer oxygen to hair follicles. Folic acid deficiency can lead to hair loss, as well as anemia and other health problems. Products rich in folic acid: green leafy vegetables (spinach, romain salad), legumes (lentils, beans), avocado, broccoli.
- Riboflavin (vitamin B2): Riboflavin is involved in energy metabolism and helps cells function correctly. Deficiency can lead to dry scalp, fragility of hair and deceleration of growth. Riboflavin is found in dairy products, meat, eggs and green vegetables.
- TIAMIN (VITAMIN B1): Tiamine is necessary for carbohydrate metabolism and helps cells receive energy. Deficiency can lead to stress, which, in turn, can adversely affect hair growth. Tiamine is found in pork, legumes and whole grains.
- Pyridoxine (vitamin B6): Pyridoxine plays a role in amino acid metabolism, which are building proteins, including keratin. Deficiency can lead to dermatitis and other scalp problems, indirectly affecting hair growth. Pyridoxine is contained in meat, fish, poultry and fruits.
Part 3: Vitamin D: sunlight and hair health
Vitamin D, known as “solar vitamin”, plays an important role in the immune system, bone health and cell growth. Recent studies have shown that vitamin D can also play a role in hair growth. Vitamin D receptors are present in hair follicles, and it is believed that it is involved in the regulation of the hair growth cycle. Vitamin D deficiency is associated with hair loss, especially with an area of the area, an autoimmune disease causing focal hair loss. Regular stay in the sun (within reasonable limits and using sunscreen) is the best way to get vitamin D. Vitamin D is also contained in fatty fish (salmon, tuna, mackerel), egg yolks and enriched products (milk, orange juice). In the winter months or with limited stay in the sun, it is recommended to take additives with vitamin D.
Part 4: Vitamin A: Hair Moisturization Regulation and Moisturization
Vitamin A is necessary for the growth and differentiation of cells, including cells of hair follicles. It also plays a role in the production of skin fat, oily substance that moisturizes the scalp and helps maintain hair health. Vitamin A deficiency can lead to dry scalp, brittle hair and growth of growth. However, it is important to note that the excess of vitamin A can also be harmful and lead to hair loss. Therefore, it is important to observe moderation in the consumption of vitamin A. Vitamin A is contained in animal products, such as liver, eggs and dairy products. It is also found in plant products in the form of beta-carotene, which the body converts into vitamin A. products rich in beta-carotene: carrots, sweet potatoes, spinach, pumpkin.
Part 5: Vitamin C: antioxidant protection and collagen synthesis
Vitamin C is a powerful antioxidant that protects the cells from damage by free radicals. Free radicals can damage the hair follicles and slow down hair growth. Vitamin C is also necessary for the synthesis of collagen, protein, which makes up the structure of hair, skin and nails. Collagen gives hair strength and elasticity. Vitamin C also helps to absorb iron, which is necessary for hair growth. Vitamin C deficiency can lead to brittle hair, loss and dry skin. Vitamin C is found in citrus fruits (oranges, lemons, grapefruit), berries (strawberries, blueberries), kiwi, Bulgarian pepper and broccoli.
Part 6: Vitamin E: Improving blood circulation and damage protection
Vitamin E is another powerful antioxidant that protects the cells from damage by free radicals. It also improves blood circulation, including in the scalp, which contributes to the delivery of oxygen and nutrients to hair follicles. Vitamin E can help reduce the scalp inflammation, which can contribute to hair loss. Vitamin E deficiency is relatively rare, but can manifest itself in the form of dry skin and brittle hair. Vitamin E is found in vegetable oils (sunflower, olive, almond), nuts (almonds, hazelnuts), seeds (sunflower seeds) and green leafy vegetables.
Part 7: Minerals supporting hair growth: iron, zinc, selenium
In addition to vitamins, some minerals play an important role in hair growth.
- Iron: Iron is necessary for the formation of hemoglobin, which tolerates oxygen in the blood. Iron deficiency (iron deficiency anemia) is one of the most common causes of hair loss, especially in women. Iron deficiency anemia can lead to thinning of the hair, a slowdown in growth and diffuse hair loss (hair loss throughout the head). Iron is found in red meat, poultry, fish, legumes (lentils, beans), spinach and enriched products. To improve the absorption of iron, it is recommended to use it along with vitamin C. It is important to consult a doctor before taking iron additives, since an excess of iron can be harmful.
- Zinc: Zinc plays an important role in the growth and restoration of fabrics, as well as in the work of the immune system. It is also necessary for the normal functioning of the sebaceous glands of the scalp. Zinc deficiency can lead to hair loss, dry scalp, dandruff and deceleration of growth. Zinc is contained in oysters, red meat, poultry, nuts (cashews, almonds), seeds (pumpkin seeds) and legumes.
- Selenium: Selenium is an antioxidant that protects the cells from damage by free radicals. It is also necessary for the normal functioning of the thyroid gland, which plays an important role in hair growth. Selena deficiency can lead to hair loss and other health problems. Selenium is found in Brazilian nuts, tuna, salmon, eggs and mushrooms.
Part 8: diet and lifestyle for healthy hair
In addition to using a sufficient amount of vitamins and minerals, it is important to adhere to a balanced diet and lead a healthy lifestyle to maintain hair health.
- Balanced diet: Use a variety of foods rich in nutrients, such as fruits, vegetables, whole grain products, low -fat meat, poultry, fish, nuts and seeds. Limit the consumption of processed products, sugar and unhealthy fats.
- Sufficient amount of protein: Protein is a building block for hair. Make sure you consume a sufficient amount of protein, about 0.8 grams per kilogram of body weight.
- Hydration: Drink enough water to maintain hydration of the body and scalp.
- Reducing stress: Stress can adversely affect hair growth. Practice stress management methods such as yoga, meditation or walking in nature.
- Correct hair care: Use soft shampoos and air conditioners, avoid frequent hair hairdressed and ironing, as well as avoid tight hairstyles that can damage the hair follicles.
- Regular physical exercises: Physical exercises improve blood circulation, including in the scalp, which contributes to the delivery of oxygen and nutrients to hair follicles.
Part 9: Addresses for hair growth: when and how to accept
Addresses for hair growth can be useful if you have a deficiency of certain vitamins or minerals. However, it is important to consult a doctor or nutritionist before starting to take any additives. They will help to determine if you have a shortage, and recommend a suitable dosage. Some additives can interact with medicines, so it is important to inform the doctor about all the additives that you accept.
- Before taking additives: Make a blood test to check the level of vitamins and minerals.
- Do not exceed the recommended dosage: Excessive consumption of some vitamins and minerals can be harmful.
- Be patient: The results from taking additives may not be visible immediately. It usually takes several months to see significant changes in hair growth.
- Combine additives with a healthy lifestyle: Additives will not replace a balanced diet and a healthy lifestyle.
Part 10: When to see a doctor
If you experience significant hair loss or other hair problems, it is important to consult a doctor or a trichologist (hair specialist). They will conduct an examination and determine the cause of hair loss. In some cases, hair loss may be a sign of a serious disease. The doctor may prescribe treatment that includes medicines, additives or other procedures.
- Significant hair loss: If more hair falls than usual.
- Sudden hair loss: If the hair began to fall out suddenly and quickly.
- Focal hair loss: If hair falls in certain areas of the head.
- Related symptoms: If hair loss is accompanied by other symptoms such as itching, redness or peeling of the scalp.
- Family history of hair loss: If your family has cases of hair loss.
Part 11: Folk remedies to stimulate hair growth (with caution)
Some folk remedies can help stimulate hair growth, but it is important to use it with caution and consult a doctor, especially if you have sensitive scalp or allergies.
- Scalp massage: Scalp massage improves blood circulation and helps the delivery of nutrients to hair follicles. You can use your fingers for soft scalp massage in a circular motion for a few minutes a day.
- Hair oils: Some oils, such as coconut oil, olive oil, castor oil and argan oil, can help moisturize the hair and scalp, strengthen the hair and reduce fragility. Apply oil to the scalp and hair, massage and leave for several hours or at night, then rinse with shampoo.
- Onion juice: Onion juice contains sulfur, which can help stimulate hair growth. Apply onion juice to the scalp, leave for 30 minutes, then rinse with shampoo. However, onion juice can cause scalp irritation in some people.
- Rice water: Rice water contains inositol, which can help strengthen the hair and make it more shiny. Soak the rice in water for 30 minutes, then strain the water and use it to rinse the hair after washing with shampoo.
It is important to remember that the effectiveness of folk remedies is not always scientifically proven, and the results can vary from person to person.
Part 12: Myths about hair growth and vitamins
There are many myths about hair growth and vitamins that do not have a scientific justification.
- Myth: taking a large number of vitamins will necessarily lead to rapid hair growth. Fact: taking a large number of vitamins will not lead to rapid hair growth if you have no shortage of these vitamins. Moreover, excessive consumption of some vitamins can be harmful.
- Myth: Hair haircut makes them faster growing. Fact: Hair haircut does not affect hair growth rate. Hair growth occurs in hair follicles, not at the end of the hair. A haircut helps to get rid of split ends and makes the hair more healthy in appearance.
- Myth: Hair growth shampoos really stimulate hair growth. Fact: most shampoos for hair growth contain ingredients that can improve blood circulation of the scalp or strengthen hair, but they do not stimulate hair growth directly.
- Myth: hair loss is an irreversible process. Fact: In some cases, hair loss can be reversible, especially if it is caused by a deficiency of vitamins or minerals, stress or hormonal changes. Treatment can help restore hair growth.
