Dad rating for rapid hair growth

Section 1: Scientific foundations of hair growth and key nutrients

1. Hair growth phases and their regulation:

   • Anagen (growth phase): This phase, which determines the length of the hair, can last from 2 to 7 years. The active division of cells in a hair follicle leads to elongation of the hair. The growth rate and duration of anagen is influenced by genetics, hormones, age and general health. The deficiency of nutrients can reduce the anagen phase, leading to a slower growth and thinning of the hair.

   • Katagen (transition phase): This phase lasts about 2-3 weeks. Hair growth stops, and the hair follicle is compressed. The blood supply to the hair follicle decreases.

   • Telogen (Phase Salm): This phase lasts about 3 months. The hair remains in the follicle, but does not grow. At the end of the heterogene, the hair falls out, and the follicle returns to the anagen phase to start a new growth cycle.

   • Exogen (falling phase): The phase in which the hair falls. This can happen during a heterogene or immediately after it. Littleing from 50 to 100 hair per day is considered normal.

   • Hormones regulation: Dihydrotestosterone (DGT) is an androgenic hormone, which can be associated with receptors in hair follicles, especially in genetically predisposed people, leading to their miniaturization and hair loss (androgenic alopecia). Estrogens, on the contrary, contribute to hair growth and prolong the anagen phase. Hormonal vibrations, such as during pregnancy or menopause, can affect the hair growth cycle.

   • Growth factors: Growth factors, such as the growth factor of vascular endothelium (VEGF) and the growth factor of fibroblasts (FGF), play a role in stimulating hair growth, improving the blood supply of hair follicles and proliferation of cells.

2. Key nutrients for hair growth:

   • Proteins (amino acids): Hair consists mainly of keratin, fibrillar protein. Sufficient protein consumption is necessary for the production of keratin and maintaining hair structure. Amino acids, such as cysteine, lysine and methionine, are key components of keratin. Protein deficiency can lead to a slowdown in growth, thinning and hair loss.
   • Iron: Iron is necessary for transferring oxygen to hair follicles. Iron deficiency (iron deficiency anemia) is a common cause of hair loss, especially in women. Iron helps the enzymes involved in the production of DNA and RNA necessary for cell growth, including the cells of the hair follicles.
   • Zinc: Zinc is involved in the synthesis of protein, cell division and functioning of the immune system. He also plays a role in maintaining the health of the sebaceous glands around the hair follicles. Zinc deficiency can lead to hair loss, dry scalp and a slowdown in hair growth.
   • Biotin (Vitamin B7): Biotin is necessary for the metabolism of fats, carbohydrates and proteins. It plays a role in the synthesis of keratin and maintaining the health of hair, skin and nails. Biotin deficiency is rare, but can lead to hair loss, fragility of nails and skin problems.
   • Vitamin D: Vitamin D plays a role in the regulation of the hair growth cycle. Studies show that vitamin D deficiency can be associated with hair loss, including focal alopecia. Vitamin D can also contribute to the proliferation of keratinocytes, skin cells, which make up the hair follicle.
   • Vitamin C: Vitamin C is an antioxidant that protects hair follicles from damage to free radicals. It is also necessary for the synthesis of collagen, protein, which provides the structure and elasticity of the skin and hair. Vitamin C also helps the body absorb iron.
   • Vitamin E: Vitamin E is another antioxidant that protects the hair follicles from damage. It can also improve blood circulation in the scalp, contributing to the growth of hair.
   • Omega-3 fatty acids: Omega-3 fatty acids contained in fish oil, flax seeds and walnuts can help reduce inflammation in the scalp and improve the health of hair follicles. They can also help moisturize the hair and scalp.
   • Other trace elements: Selenium, silicon and magnesium also play a role in maintaining hair health, although their influence is less studied than the influence of the main vitamins and minerals.

Section 2: Review of popular dietary supplements for hair growth and their composition

1. Bado -based dietary supplements:

   • The mechanism of action: Biotin improves the metabolism of keratin, the main protein, of which the hair consists of. It also participates in the synthesis of fatty acids necessary for the health of the scalp.
   • Dosage: It is usually recommended a dosage of 2.5-5 mg per day.
   • Efficiency: The most effective in people with a deficiency of biotin. Clinical trials have shown that additives with biotin can improve hair growth, hair thickness and nail strength in people with deficiency.

   • Types of collagen: Various types of collagen (type I, type III) are contained in various body tissues. Type I and III collagen are often used in additions for hair, skin and nails. Sea collagen (obtained from fish) is considered easily digestible.
   • Dosage: It is usually recommended a dosage of 5-10 grams per day.
   • Efficiency: Some studies show that additives with collagen can improve skin hydration, skin elasticity and hair thickness. Additional studies are needed to confirm the effectiveness of collagen for hair growth.
   • Side effects: Usually well tolerated. In rare cases, digestive problems can cause, such as bloating or heartburn.
   • Examples of brands: Vital Proteins Collagen Peptides, Neocell Super Collagen, Ancient Nutrition Multi Collagen Protein.

3. Bades based on vitamins and minerals (multivitamins for hair):

   • Composition: They usually contain a combination of vitamins A, C, D, E, B vitamins (including biotin, folic acid, niacin), iron, zinc, selenium and other trace elements.
   • The mechanism of action: Provide the body with the necessary nutrients that can be scarce in the diet. Vitamins and minerals are involved in various processes necessary for the growth and health of hair, including protein synthesis, energy metabolism, antioxidant protection and functioning of the immune system.
   • Dosage: Follow the instructions on the packaging.
   • Efficiency: Effective for people with a deficiency of nutrients. They can help improve hair growth, hair thickness, shine of hair and the general condition of the scalp.
   • Side effects: They can cause side effects if taken in large doses. For example, an excess of vitamin A can be toxic. Iron can cause constipation.
