Vitamin’s diet for optimal hair growth: deep immersion
Hair growth is a complex biological process that depends on many factors, including genetics, hormones and, of course, nutrition. The lack of certain vitamins and minerals can lead to a slowdown in growth, loss, brittleness and dullness of hair. Understanding the role of key vitamins and minerals, as well as ways to include them in the diet, is crucial for achieving healthy and lush hair. This article offers a comprehensive analysis of the vitamins necessary for hair growth, with a detailed description of their functions, the best food sources and the consequences of the deficit.
1. Vitamin A: Cellular growth regulator and sebum production
Vitamin A is a fat -soluble vitamin that plays an important role in various physiological processes, including vision, immune function and cell growth. In the context of hair health, vitamin A is necessary to maintain healthy scalp and optimal hair growth.
- The mechanism of action: Vitamin A stimulates cell growth, including hair follicles, providing a continuous hair growth cycle. It also contributes to the production of sebum, natural skin, which moisturizes the scalp and nourishes hair, preventing dryness and brittleness.
- The consequences of the deficit: Vitamin A deficiency can lead to dry scalp, dandruff, itching and slowing down hair growth. In severe cases, hair loss may be observed.
- Sources of vitamin A:
- Retinol (active form): Liver, fish oil, egg yolks, dairy products.
- Beta-carotene (provitamin A): Carrots, sweet potatoes, spinach, cabbage, pumpkin, mango, apricots.
Important: Excessive consumption of vitamin A can be toxic and lead to hair loss. It is recommended to receive vitamin A mainly from food sources, and not from additives, and observe the recommended daily dose.
2. B vitamins B: Energy for hair follicles
B vitamins are a group of water -soluble vitamins necessary for the metabolism of energy, the function of the nervous system and the health of cells. Several vitamins of group B play a key role in hair growth, including biotin (B7), niacin (B3), pantothenic acid (B5) and folic acid (B9).
- 2.1. BIOTIN (vitamin B7): Fortress and elasticity of hair
Biotin is probably the most famous vitamin for hair growth, often added to shampoos, air conditioners and food supplements. It plays an important role in the synthesis of keratin, the main protein, of which the hair consists of.

It also stimulates the production of collagen, which strengthens the hair and makes it more resistant to damage. In addition, vitamin C helps the body absorb iron, mineral necessary for hair growth.
- The consequences of the deficit: Vitamin C deficiency can lead to dryness, brittleness and split ends. It can also lead to scurvy, a state characterized by bleeding gums, weakness and hair loss.
- Sources of vitamin C: Citrus fruits (oranges, lemons, grapefruits), strawberries, kiwi, pepper, broccoli, cabbage.
4. Vitamin D: growth of hair follicles and phase of anagen
Vitamin D is a fat -soluble vitamin that plays an important role in various physiological processes, including bone health, immune function and cell growth. Studies show that vitamin D also plays a role in hair growth.
- The mechanism of action: Vitamin D stimulates the growth of new hair follicles and helps to maintain the anagen phase, the phase of active hair growth. Studies have shown the relationship between vitamin D deficiency and hair loss, especially with alopecia.
- The consequences of the deficit: Vitamin D deficiency can lead to hair loss, especially with focal alopecia.
- Sources of vitamin D: Sunlight (the best source), fatty fish (salmon, tuna, sardines), egg yolks, enriched dairy products, vitamin D.
Important: The amount of vitamin D, which the body can synthesize under the influence of sunlight, depends on many factors, including the geographical position, season, skin color and the use of sunscreen. Therefore, many people need an additional intake of vitamin D in the form of additives, especially in the winter months.
5. Vitamin E: antioxidant protection and improving blood circulation
Vitamin E is a powerful antioxidant that protects the cells from damage by free radicals. It also improves blood circulation in the scalp, providing hair follicles with the necessary nutrients and oxygen.
- The mechanism of action: Vitamin E neutralizes free radicals that can damage the hair follicles and slow down hair growth. It also improves blood circulation in the scalp, providing hair follicles with the necessary nutrients and oxygen.
- The consequences of the deficit: Vitamin E deficiency is rare, but can lead to dry hair, brittle hair and hair loss.
