TOP Ingredients in Dietary Dietary Bades for Hair Growth: A Comprehensive Guide

Section 1: Vitamins – the foundation of healthy hair growth

Vitamins play a key role in maintaining the health of hair follicles and stimulating hair growth. The deficiency of certain vitamins can lead to hair loss, a slowdown in growth and a deterioration in their quality.

  • Vitamin A (Retinol):

    • The mechanism of action: Vitamin A is necessary for the growth and differentiation of all cells of the body, including cells of hair follicles. It contributes to the production of sebum, which moisturizes the scalp and hair, preventing their dryness and brittleness. Retinoids derivatives of vitamin A regulate the expression of genes involved in the growth and differentiation of cells.
    • Hair benefits: Improves the health of the scalp, promotes hair growth, prevents dryness and brittleness. Supports the optimal condition of the sebaceous glands.
    • Recommended dosage: 900 mcg per day for men and 700 mcg per day for women.
    • Sources: Fish oil, liver, dairy products, eggs, green and yellow vegetables (carrots, pumpkin, spinach).
    • Cautions: Excess vitamin A can be toxic and lead to hair loss, headaches, nausea and liver damage. Pregnant women should avoid high doses of vitamin A due to the risk of congenital defects.

  • B vitamins B:

    • Biotin (Vitamin B7):
      • The mechanism of action: Biotin is a cooferment involved in the metabolism of carbohydrates, fats and proteins. It plays an important role in the synthesis of keratin, the main protein that makes up hair, skin and nails. Biotin also helps to improve blood circulation in the scalp, which ensures the flow of the necessary nutrients to hair follicles.
      • Hair benefits: Strengthens hair, reduces loss, stimulates growth, improves hair structure, gives shine. Especially effective in case of biotin deficiency.
      • Recommended dosage: 30 mcg per day.
      • Sources: Eggs, liver, yeast, nuts, seeds, salmon, avocados, sweet potatoes.
      • Cautions: In rare cases, biotin can interact with some drugs. High doses of biotin can distort the results of some laboratory tests (for example, tests for thyroid hormones).
    • Niacin (Vitamin B3):
      • The mechanism of action: Niacin improves blood circulation, expanding blood vessels, which helps the delivery of oxygen and nutrients to hair follicles. He also plays a role in the metabolism of energy and the synthesis of hormones.
