Vitamins for hair growth: for women

Introduction to the world of vitamins for hair growth in women

Hair loss and slow growth are the common problems that many women face. There can be many reasons for this: stress, hormonal changes, malnutrition, lack of vitamins and minerals, genetic predisposition, aggressive cosmetic procedures and diseases. While eliminating the root cause is the key to the long -term solution, the inclusion of certain vitamins and nutrients in the diet and hair care can significantly stimulate growth, strengthen hair follicles and improve the overall condition of the hair. In this article, we will consider various vitamins and nutrients that play a key role in maintaining healthy hair growth in women, as well as ways to obtain them and potential risks. We will delve into scientific research on the effectiveness of each vitamin, and provide practical advice on their use to achieve optimal results.

Chapter 1: Vitamin A is the basis for healthy scalp and hair growth

Vitamin A is a fat -soluble vitamin necessary for the growth and differentiation of all body cells, including cells of hair follicles. It plays an important role in the production of skin fat – an oily substance secreted by the sebaceous glands of the scalp. The skin moisturizes the scalp and hair, preventing their dryness, brittleness and damage. The disadvantage of vitamin A can lead to dry scalp, itching, dandruff and, as a result, to a slowdown in hair growth and their loss. On the other hand, an excess of vitamin A can also be harmful and cause hair loss, so it is important to maintain balance.

• The mechanism of action: Vitamin A contributes to the division and growth of cells of hair follicles, thereby providing healthy hair growth. It also regulates the production of skin fat, supporting the moisture of the scalp and preventing dryness and peeling. In addition, vitamin A has antioxidant properties, protecting the hair follicles from damage to free radicals.
• Sources of vitamin A: There are two types of vitamin A: retinol (contained in animal products) and beta-carotene (contained in plant products, which the body converts into retinol). Good sources of retinol are: liver, fish oil, egg yolks, dairy products. Beta-carotene can be found in: carrots, sweet potatoes, spinach, cabbage, pumpkin and other orange and dark green vegetables and fruits.
• Recommended dosage: The recommended daily dose of vitamin A for women is 700 mcg (micrograms) of retinol equivalent (RAE). It is important to note that an excess of vitamin A can be toxic, so you should not exceed the upper permissible level of consumption, which is 3000 mcg RAE per day. Before taking the additives with vitamin A, it is recommended to consult a doctor.
• Research: Studies have shown that vitamin A deficiency can lead to dry scalp and hair loss. For example, a study published in the Journal of the American Academy of Dermatology showed that people with vitamin A deficiency are more likely to have dry scalp and hair loss. However, it is important to note that most studies are focused on the influence of vitamin A deficiency, and not on the effect of taking additional doses of hair growth in people with a sufficient level of vitamin A.
• Cautions: Pregnant women should be especially careful with the use of vitamin A, since its excess can cause congenital defects. Also, simultaneous intake of vitamin A should be avoided with certain drugs, such as retinoids used to treat acne.

Chapter 2: B vitamins – the key to energy and healthy hair follicles

B vitamins, also known as the B-complex, play a vital role in the metabolism of the energy necessary for the growth and functioning of all cells of the body, including the cells of the hair follicles. The deficiency of group B vitamins can lead to a slowdown in hair growth, their loss, as well as to other problems, such as dandruff and itching of the scalp. The most important vitamins of group B for hair health are:

• Biotin (Vitamin B7): Biotin, perhaps the most famous vitamin for hair health. It is necessary for the synthesis of keratin – the main protein of which the hair consists of. Biotin also plays an important role in the metabolism of fats and carbohydrates necessary to provide the energy of hair follicles.

  • The mechanism of action: Biotin is involved in carboxylation – the process necessary for the synthesis of fatty acids, which make up the structure of cells and provide energy. It is also important for the metabolism of amino acids, building blocks of proteins, such as keratin.
  • Sources of biotin: Biotin is found in various foods, such as egg yolks, liver, yeast, nuts, seeds, avocados, salmon and sweet potatoes.
  • Recommended dosage: The recommended daily dose of biotin for adults is 30 μg. Biotin is considered safe vitamin, and even with high doses, side effects rarely occur.
  • Research: Numerous studies have shown that taking biotin can improve the condition of hair in people with a deficiency of this vitamin. For example, a study published in the journal Journal of Clinical and Aesthetic Dermatology showed that taking biotin for several months improved the thickness and strength of hair in women with thinning. However, it is important to note that taking biotin will not have a significant effect on hair growth in people who do not have a deficiency of this vitamin. It is also important to take into account that biotin can affect the results of some laboratory tests, so before the tests it is necessary to inform the doctor about the biotin.
  • Cautions: In rare cases, biotin’s intake can cause side effects, such as nausea, diarrhea and skin rashes.

• Niacin (Vitamin B3): Niacin helps to improve blood circulation in the scalp, ensuring the delivery of nutrients and oxygen to hair follicles. It also plays an important role in the production of energy and maintaining skin health.

  • The mechanism of action: Niacin expands blood vessels, improving blood flow in the scalp. This ensures the flow of more nutrients and oxygen to hair follicles, which stimulates hair growth and strengthens their roots.
  • Sources of Niacin: Niacin is contained in foods such as meat, fish, poultry, nuts, seeds, legumes and whole grains.
  • Recommended dosage: The recommended daily dose of niacin for women is 14 mg.
  • Research: Studies have shown that niacin can improve blood circulation in the scalp and stimulate hair growth. However, additional studies are needed to confirm these results.
  • Cautions: Reception of high doses of niacin can cause redness of the skin, itching and burning. People with liver diseases should avoid taking high doses of niacin.

• Pantotenic acid (vitamin B5): Pantotenic acid is necessary for the health of hair follicles and plays an important role in the metabolism of fats and carbohydrates. It also helps to moisturize the hair and prevents their dryness and brittleness.

  • The mechanism of action: Pantotenic acid is a component of Coenzyme A (COA), which is necessary for many metabolic processes, including the synthesis of fatty acids, cholesterol and hormones. It also helps to moisturize the hair, making it more elastic and resistant to damage.
  • Sources of pantothenic acid: Pantotenic acid is contained in many foods, such as meat, poultry, fish, eggs, dairy products, vegetables and whole grains.
  • Recommended dosage: The recommended daily dose of pantothenic acid for adults is 5 mg.
  • Research: Studies have shown that pantothenic acid can improve the condition of the hair and prevent their loss. However, additional studies are needed to confirm these results.
  • Cautions: Pantotenic acid is considered safe vitamin, and even with high doses, side effects rarely occur.

• Vitamin B12 (cobalamin): Vitamin B12 plays an important role in the formation of red blood cells, which cause oxygen and nutrients to hair follicles. Vitamin B12 deficiency can lead to anemia, which can cause hair loss.

  • The mechanism of action: Vitamin B12 is necessary for the synthesis of DNA and RNA, as well as for the formation of myelin – a protective shell of nerve fibers. It also plays an important role in the metabolism of homocysteine, the high level of which can negatively affect the health of the heart and blood vessels.
  • Sources of vitamin B12: Vitamin B12 is contained in animal products, such as meat, fish, poultry, eggs and dairy products. Vegetarians and vegans need to take additives with vitamin B12 to prevent a deficiency of this vitamin.
  • Recommended dosage: The recommended daily dose of vitamin B12 for adults is 2.4 μg.
  • Research: Studies have shown that vitamin B12 deficiency can lead to hair loss. Reception of additives with vitamin B12 can improve the condition of hair in people with a deficiency of this vitamin.
  • Cautions: Vitamin B12 is considered safe vitamin, and even with high doses, side effects rarely occur.

• Folic acid (vitamin B9): Folic acid is necessary for the division and growth of cells, including cells of hair follicles. It also plays an important role in the formation of red blood cells and prevents anemia.

  • The mechanism of action: Folic acid is involved in the synthesis of DNA and RNA, as well as in amino acid metabolism. It is also important to prevent congenital defects in the nervous tube in the fetus, so pregnant women are recommended for its use.
  • Folic acid sources: Folic acid is contained in foods such as dark green leafy vegetables, legumes, citrus fruits and enriched grain products.
  • Recommended dosage: The recommended daily dose of folic acid for adults is 400 mcg. Pregnant women are recommended to take 600 μg of folic acid per day.

Chapter 3: Vitamin C – A powerful antioxidant to protect hair follicles

Vitamin C is a powerful antioxidant that protects the cells of the body, including cells of hair follicles, from damage to free radicals. Free radicals are unstable molecules that can damage cells and DNA, which can lead to a slowdown in hair growth and their loss. Vitamin C is also necessary for the synthesis of collagen – a protein that provides the structure and strength of the hair.

• The mechanism of action: Vitamin C neutralizes free radicals, protecting the hair follicles from damage. It also participates in the synthesis of collagen, which makes the hair more durable and elastic. In addition, vitamin C improves the absorption of iron from food, which is also important for hair health.
• Sources of vitamin C: Vitamin C is contained in various fruits and vegetables, such as citrus fruits (oranges, lemons, grapefruits), kiwi, strawberries, black currants, bell pepper, broccoli and spinach.
• Recommended dosage: The recommended daily dose of vitamin C for women is 75 mg. Smokers are recommended to take more vitamin C, as smoking increases the body’s need for this vitamin.
• Research: Studies have shown that vitamin C can improve the condition of the hair and prevent their loss. For example, a study published in the journal Journal of Investigative Dermatology showed that vitamin C protects hair follicles from damage to free radicals.
• Cautions: Vitamin C is considered safe vitamin, and even with high doses, side effects rarely occur. In rare cases, taking high doses of vitamin C can cause stomach disorder.

Chapter 4: Vitamin D – hair growth regulator and scalp health

Vitamin D plays an important role in the regulation of hair growth and maintaining the health of the scalp. It helps to regulate the hair growth cycle, stimulating the transition of hair follicles from the dormancy phase (bodyogen) to the growth phase (anagen). Vitamin D deficiency can lead to a slowdown in hair growth, their loss and other problems, such as dandruff and itching of the scalp.

• The mechanism of action: Vitamin D interacts with vitamin D (VDR) receptors, which are in hair follicles. Activation of VDR stimulates hair growth and differentiation of hair follicles cells. Vitamin D also has anti -inflammatory properties that can help reduce the scalp and improve its health.
• Sources of vitamin D: Vitamin D is produced in the skin under the influence of sunlight. It is also contained in some foods, such as fatty fish (salmon, tuna, mackerel), egg yolks and enriched products (milk, flakes).
• Recommended dosage: The recommended daily dose of vitamin D for adults is 600 IU (international units). People with vitamin D deficiency may require a higher dose.
• Research: Numerous studies have shown that vitamin D deficiency can lead to hair loss. For example, a study published in Dermatology Online Journal showed that women with hair loss (hair loss in the bodyogen phase) more often occurs a deficiency of vitamin D.
• Cautions: Taking high doses of vitamin D can be toxic and cause side effects such as nausea, vomiting, weakness and constipation. Before taking the additives with vitamin D, it is recommended to consult a doctor.

Chapter 5: Vitamin E – antioxidant to protect against damage and improve blood circulation

Vitamin E is a fat -soluble antioxidant that protects the body cells from damage by free radicals.

It also improves blood circulation in the scalp, expanding blood vessels and providing the flow of more nutrients and oxygen to hair follicles. In addition, vitamin E has anti -inflammatory properties that can help reduce scalp inflammation.
• Sources of vitamin E: Vitamin E is contained in foods such as vegetable oils (sunflower, olive, almond), nuts (almonds, hazelnuts, walnuts), seeds (sunflower, pumpkin), avocados and green leafy vegetables.
• Recommended dosage: The recommended daily dose of vitamin E for adults is 15 mg.
• Research: Studies have shown that vitamin E can improve the condition of the hair and prevent their loss. For example, a study published in the journal Tropical Life Sciences Research showed that taking additives with vitamin E has improved hair growth in people with hair loss.
• Cautions: Vitamin E is considered safe vitamin, and even with high doses, side effects rarely occur. In rare cases, taking high doses of vitamin E can cause stomach disorder.

Chapter 6: Minerals – necessary elements for hair health

In addition to vitamins, minerals play an important role in maintaining healthy hair growth. The lack of certain minerals can lead to a slowdown in hair growth, their loss and other problems.

• Iron: Iron is necessary for the formation of hemoglobin, which tolerates oxygen in the blood. Iron deficiency can lead to anemia, which can cause hair loss.

  • The mechanism of action: Iron is involved in the formation of red blood cells, which deliver oxygen to hair follicles. The lack of iron leads to a decrease in the amount of oxygen coming to the hair follicles, which can slow down their growth and lead to hair loss.
  • Iron sources: Iron is found in foods such as red meat, poultry, fish, legumes, dark green leafy vegetables and enriched grain products. There are two types of iron: hemic iron (contained in animal products) and non -meter iron (contained in plant products). Hemic iron is better absorbed than non -meter iron. To improve the absorption of a non -meter iron, it is recommended to use it along with products rich in vitamin C.
  • Recommended dosage: The recommended daily dose of iron for women aged 19 to 50 years is 18 mg. Pregnant women need 27 mg of iron per day.
  • Research: Numerous studies have shown that iron deficiency can lead to hair loss. For example, a study published in the journal Journal of the American Academy of Dermatology showed that women with hair loss are more often found in iron.
  • Cautions: The use of too much iron can be toxic and cause side effects such as constipation, nausea and vomiting. Before taking the additives with iron, it is recommended to consult a doctor.

• Zinc: Zinc is necessary for the growth and restoration of tissues, including cells of hair follicles. It also plays an important role in maintaining the health of the scalp and prevents its inflammation.

  • The mechanism of action: Zinc is involved in the synthesis of proteins necessary for hair growth. It also regulates the production of skin fat and prevents inflammation of the scalp.
  • Sources of zinc: Zinc is contained in foods such as oysters, red meat, poultry, nuts, seeds, legumes and whole grain products.
  • Recommended dosage: The recommended daily zinc dose for women is 8 mg.
  • Research: Studies have shown that zinc deficiency can lead to hair loss. For example, a study published in the journal Annals of Dermatology showed that taking the supplements with zinc improved hair growth in people with a deficiency of this mineral.
  • Cautions: Taking too much zinc can cause such side effects as nausea, vomiting and stomach disorder. He can also reduce the absorption of other minerals such as copper. Before taking the additives with zinc, it is recommended to consult a doctor.

• Selenium: Selenium is an antioxidant that protects the body cells from damage by free radicals. It is also necessary for the health of the thyroid gland, which plays an important role in regulatory regulation, including hair growth.

  • The mechanism of action: Selenium is involved in the synthesis of selenoproteins, which have antioxidant properties and protect the cells from damage to free radicals. It is also necessary for the production of thyroid hormones, which regulate the metabolism and hair growth.
  • Sources of Selena: Selenium is found in foods such as Brazilian nuts, fish, seafood, meat, poultry and whole grain products.
  • Recommended dosage: The recommended daily dose of selenium for adults is 55 μg.
  • Research: Studies have shown that selenium deficiency can lead to hair loss. Reception of additives with selenium can improve the condition of hair in people with a deficiency of this mineral.
  • Cautions: Acceptance of too much selenium can be toxic and cause side effects such as nausea, vomiting, diarrhea, hair loss and damage to the nervous system. Before taking the additives with selenium, it is recommended to consult a doctor.

Chapter 7: Other nutrients that contribute to hair growth

In addition to vitamins and minerals, there are other nutrients that can contribute to hair growth:

• Omega-3 fatty acids: Omega-3 fatty acids are indispensable fatty acids that are necessary for the health of the heart, brain and skin. They can also contribute to hair growth, reducing the scalp and improving blood circulation.

  • The mechanism of action: Omega-3 fatty acids have anti-inflammatory properties that can help reduce scalp inflammation and improve its health. They also help improve blood circulation in the scalp, ensuring the delivery of nutrients and oxygen to hair follicles.
  • Sources of omega-3 fatty acids: Omega-3 fatty acids are found in fatty fish (salmon, tuna, mackerel), linseed seeds, chia seeds, walnuts and vegetable oils (linen, rapeseed).
  • Recommended dosage: The recommended daily dose of omega-3 fatty acids varies depending on the source. To maintain health, it is recommended to use at least 250-500 mg EPA (eicopascentenic acid) and DHA (non-zahyxaic acid) per day.
  • Research: Studies have shown that the intake of omega-3 fatty acids can improve the condition of the hair and prevent their loss. For example, a study published in Journal of Cosmetic Dermatology showed that taking additives with omega-3 and omega-6 fatty acids improved hair density in women with hair loss.
  • Cautions: Omega-3 fatty acids are considered safe for most people. However, when taking high doses, side effects can occur, such as stomach disorder and bleeding.

• Protein: Protein is the main building material for hair. Hair consists mainly of keratin, which is a protein. The lack of protein in the diet can lead to a slowdown in hair growth, their thinning and brittleness.

  • The mechanism of action: The protein provides the building blocks necessary for the synthesis of keratin – the main protein from which the hair consists of. The lack of protein leads to a decrease in keratin synthesis, which can slow down hair growth and make it weaker and brittle.
  • Springs of protein: Protein is found in foods such as meat, poultry, fish, eggs, dairy products, legumes, nuts and seeds.
  • Recommended dosage: The recommended daily dose of adult protein is 0.8 grams per kilogram of body weight.
  • Research: Studies have shown that the lack of protein can lead to hair loss. Reception of a sufficient amount of protein can improve the condition of the hair and stimulate their growth.
  • Cautions: Acceptance of too much protein can be harmful to health, especially for people with kidney diseases.
