Overview of the main components of dietary supplements for hair growth

The effectiveness of dietary supplement for hair growth is largely determined by its composition. The key ingredients that are often found in such additives are vitamins, minerals, amino acids, plant extracts and other biologically active substances. Each of these components plays a certain role in maintaining hair health and stimulating their growth.

• Vitamins: Vitamins are indispensable nutrients necessary for the normal functioning of the body, including for hair health.

  • Vitamin A: This vitamin is necessary for the growth and differentiation of cells, including cells of hair follicles. Vitamin A deficiency can lead to dry hair. However, excessive consumption of vitamin and can also be harmful and cause hair loss.
  • B vitamins B: This group of vitamins plays an important role in energy metabolism and DNA synthesis, which are necessary for hair growth.
    • Biotin (Vitamin B7): Biotin is perhaps the most famous hair vitamin. It is involved in the metabolism of fats, carbohydrates and proteins that are necessary for building keratin – the main structural component of the hair. Biotin deficiency can lead to hair loss, fragility of nails and skin problems. However, a biotin deficiency is relatively rare, and in most cases, an additional intake of biotin does not have a significant effect on hair growth in people without deficiency.
    • Niacin (Vitamin B3): Niacin improves blood circulation, which can contribute to better nutrition of hair follicles.
    • Pantotenic acid (vitamin B5): Pantotenic acid is involved in cell metabolism and helps to moisturize the hair.
    • Vitamin B12: Vitamin B12 is necessary for the formation of red blood cells, which cause oxygen and nutrients to hair follicles. Vitamin B12 deficiency can lead to anemia and, as a result, to hair loss.
  • Vitamin C: This vitamin is a powerful antioxidant that protects the hair follicles from damage to free radicals. In addition, vitamin C is necessary for the synthesis of collagen, which gives hair strength and elasticity.
  • Vitamin D: Vitamin D plays an important role in the regulation of hair growth. Studies show that vitamin D deficiency can be associated with hair loss, especially with focal alopecia.
  • Vitamin E: This vitamin is also an antioxidant and helps to improve blood circulation in the scalp.

• Minerals: Minerals are no less important for hair health than vitamins.

  • Iron: Iron is necessary for the formation of hemoglobin, which transfers oxygen to the cells of the body, including hair follicles. Iron deficiency is one of the most common causes of hair loss, especially in women.
  • Zinc: Zinc is involved in many biochemical processes in the body, including protein synthesis and cell division. Zinc deficiency can lead to hair loss, slowing down their growth and dry scalp.
  • Selenium: Selenium is an antioxidant that protects the hair follicles from damage. It is also necessary for the normal function of the thyroid gland, which plays an important role in the regulation of hair growth.
  • Magnesium: Magnesium is involved in many enzymatic reactions necessary for hair growth. It also helps to reduce stress, which can be a factor contributing to hair loss.

• Amino acids: Amino acids are construction blocks of proteins, including keratin, the main structural component of the hair.

  • L-Cistein: L-cysteine ​​is a sulfur-containing amino acid that plays an important role in the formation of disulfide bonds that ensure the strength and stability of keratin.
  • L-Lisin: L-lysine is an indispensable amino acid that is necessary for the synthesis of collagen and the absorption of iron. L-lyzine deficiency can lead to hair loss.
  • L-metionine: L-metionine is another sulfur-containing amino acid that is involved in the synthesis of keratin.

• Plant extracts: Many dietary supplements for hair growth contain plant extracts, which are believed to have useful properties for hair.

  • SAW Palmetto palm extract: This extract blocks the action of digidrotestosterone (DGT), a hormone that plays an important role in the development of androgenetic alopecia (baldness according to the male type).
  • Horsetail extract of field (Horsetail Extract): Field horsetail is rich in silicon, which is believed to strengthens the hair and stimulates their growth.
  • Green Tea Extract (Green Tea Extract): Green tea extract contains antioxidants that protect hair follicles from damage.

  • GINSENG EXTRACT Extract): Ginseng can stimulate blood circulation in the scalp, which can contribute to better nutrition of hair follicles.

• Other biologically active substances:

  • Collagen: Collagen is a structural protein that gives hair strength and elasticity.
  • Hyaluronic acid: Hyaluronic acid moisturizes the hair and scalp.
  • Omega-3 fatty acids: Omega-3 fatty acids have anti-inflammatory properties and can help improve the health of the scalp.

Mechanisms for the action of dietary supplements for hair growth

• Protection against oxidative stress: The antioxidants contained in some dietary supplements can protect hair follicles from damage to free radicals caused by oxidative stress.
• Blocking the action of dihydrotestosterone (DGT): Some dietary supplements contain ingredients, such as the extract of the cuts of serenia, which can block the action of DGT, a hormone, which plays an important role in the development of androgenetic alopecia.
• Keratin synthesis stimulation: Some dietary supplements contain ingredients such as L-cysteine, which can stimulate the synthesis of keratin, the main structural component of the hair.
• Reducing inflammation: Some dietary supplements contain ingredients such as omega-3 fatty acids that have anti-inflammatory properties and can help improve the health of the scalp.

Evidence base for the effectiveness of dietary supplements for hair growth

It is important to note that the evidence base of the effectiveness of dietary supplements for hair growth is often limited. Many studies are small, short -lived and have methodological disadvantages. Therefore, the results of these studies should be interpreted with caution.

Biotin deficiency is relatively rare, and in most cases, an additional intake of biotin does not have a significant effect on hair growth in people without deficiency.
• Vitamin D: Some studies show that vitamin D deficiency can be associated with hair loss, especially with focal alopecia. In such cases, taking additives with vitamin D can be useful.
• Iron: Iron deficiency is one of the most common causes of hair loss, especially in women. In such cases, taking iron additives can be effective for restoring hair growth.

• Serene palm extract: Some studies show that the extract of the palm palm can be effective for the treatment of androgenetic alopecia in men, since it blocks the action of DGT.
• Other ingredients: Evidence of the effectiveness of other ingredients often found in dietary supplements for hair growth, such as horsetail extract, green tea extract, nettle extract, ginseng extract, collagen, hyaluronic acid and omega-3 fatty acids are limited and require additional studies.
