Hair dietary supplements: contraindications and side effects

I. Introduction to the world of hair dietary

Bades (biologically active additives) have become a popular way to combat loss, thinning and deterioration of hair quality. They promise to strengthen the roots, stimulate growth, give shine and restore the structure of the hair. However, like any other substance taken inside, dietary supplements can have contraindications and cause side effects. It is important to understand that dietary supplements are not medicines and do not go through the same strict clinical trials as drugs. Therefore, before starting to take any hair additives, it is necessary to carefully study their composition, possible risks and consult a doctor or a trichologist.

II. The main components of hair dietary supplements and their action

Most hair dietary supplements contain various vitamins, minerals, amino acids, plant extracts and other biologically active substances. Each component performs its own function aimed at improving hair health. Consider the most common ingredients:

• B vitamins B (B1, B2, B3, B5, B6, B7, B9, B12): These vitamins play a key role in cellular metabolism, growth and cell division, including cells of hair follicles.

  • Vitamin B1 (TIAMIN): Participates in energy metabolism, necessary for the normal functioning of the nervous system, which indirectly affects the health of the hair, since stress can cause hair loss.
  • Vitamin B2 (Riboflavin): Participates in redox processes, necessary for the health of the scalp and hair. Riboflavin deficiency can lead to dry skin, dandruff and hair loss.
  • Vitamin B3 (Niacin): Improves blood microcirculation in the scalp, providing hair follicles with the necessary nutrients. Niacin deficiency can cause dermatitis and hair loss.
  • Vitamin B5 (pantotenic acid): Participates in the synthesis of coenzyme A necessary for the metabolism of fats, carbohydrates and proteins. Helps strengthen the structure of the hair, gives it shine and prevents gray hair.
  • Vitamin B6 (Pyridoxin): Amino acids are necessary for the metabolism, which are building proteins, including keratin – the main protein of hair. Pyridoxine deficiency can lead to hair loss and dermatitis.
  • Vitamin B7 (Biotin): One of the most famous hair vitamins. Participates in the metabolism of fats, carbohydrates and proteins. Strengthens the hair, stimulates their growth and prevents fragility. Biotin deficiency can lead to hair loss, dry skin and fragility of nails.
  • Vitamin B9 (folic acid): It is necessary to divide and growth of cells, including cells of hair follicles. Folic acid deficiency can lead to hair loss and anemia.
  • Vitamin B12 (cobalamin): Participates in hematopoietic and necessary for the normal functioning of the nervous system. Cobalamin deficiency can lead to anemia, which, in turn, can cause hair loss.

• Vitamin A (Retinol): It is necessary for the growth and differentiation of cells, including cells of hair follicles. Participates in the production of sebum, which moisturizes the scalp and hair. However, excess vitamin A can lead to hair loss.

• Vitamin C (ascorbic acid): A powerful antioxidant that protects the cells from damage caused by free radicals. Participates in the synthesis of collagen necessary for the health of the skin and hair. Improves the absorption of iron, which is also important for hair growth.

• Vitamin D (calciferol): He plays a role in the regulation of hair growth and can affect the hair growth cycle. Vitamin D deficiency is associated with various types of hair loss, including focal alopecia.

• Vitamin E (Tokoferol): An antioxidant that protects the cells from damage caused by free radicals. Improves blood microcirculation in the scalp, providing hair follicles with the necessary nutrients.

• Minerals:

  • Iron: It is necessary to transfer oxygen to cells, including cells of hair follicles. Iron deficiency is one of the most common causes of hair loss, especially in women.

  • Selenium: An antioxidant that protects the cells from damage caused by free radicals. It is necessary for the normal function of the thyroid gland, which plays an important role in hair growth. Selena deficiency can lead to hair loss and other health problems.
  • Magnesium: Participates in more than 300 enzymatic reactions in the body, including the synthesis of proteins necessary for hair growth. Helps reduce stress that can cause hair loss. Magnesium deficiency can lead to hair loss, fragility of nails and muscle spasms.
  • Copper: It is necessary for the synthesis of melanin, pigment that determines the color of the hair. Participates in the formation of collagen necessary for the health of the skin and hair. The shortage of copper can lead to hair loss and premature gray hair.
  • Calcium: It is necessary for the health of bones and teeth, as well as for the normal functioning of the nervous system and muscles. Although calcium does not directly affect hair growth, it is important for the overall health of the body, which indirectly affects the health of the hair.
  • Silicon: Strengthens the structure of hair and nails, gives them shine and elasticity. Participates in collagen synthesis.

• Amino acids:

  • L-Cistein: The main amino acid that is part of keratin is the main protein of the hair. Strengthens the structure of the hair, gives them strength and elasticity.
  • L-Lisin: It is necessary for the synthesis of collagen, which strengthens the hair and scalp. Improves the absorption of iron.
  • Methionine: An antioxidant that protects the cells from damage caused by free radicals. Participates in the synthesis of keratin.

• Plant extracts:

  • SAW Palmetto palm extract: Blocks the action of digidrotestosterone (DGT), a hormone, which is the main cause of androgenic alopecia (male baldness).
