Hair vitamins in dietary supplements

Hair vitamins in dietary supplements: deep analysis and practical guide

1. Understanding the nature of the problem: why hair needs vitamin support

Hair health, their strength, brilliance and density — a reflection of the general state of the body. Hair, although it seems simple structures, are biochemically active formations that require the constant intake of nutrients for normal growth and functioning. Hair problems, such as falling out, fragility, dryness, dullness, slow growth, split ends, often indicate a deficiency of vitamins and minerals.

Factors that negatively affect hair health and increase the need for nutrients include:

• Unstable nutrition: Deficiency of protein, fats, carbohydrates, vitamins and minerals necessary for the synthesis of keratin — the main building material of the hair.
• Stress: Chronic stress affects the hormonal background, worsens the blood supply to the hair follicles and disrupts the absorption of nutrients.
• Age changes: With age, the rate of metabolism decreases and the body’s ability to absorb nutrients is deteriorating, which leads to thinning and hair loss.
• Hormonal malfunctions: The imbalance of hormones, especially androgens (in men) and estrogen (in women), can cause hair loss.
• Diseases: Some diseases, such as thyroid diseases, autoimmune diseases, anemia, can negatively affect hair health.
• Medicines: Taking certain drugs, such as antidepressants, contraceptives, chemotherapeutic drugs, can cause hair loss.
• Aggressive effect of the external environment: Excessive exposure to ultraviolet radiation, contaminated air, chlorinated water damages the hair structure and leads to their dryness and brittleness.
• Incorrect care: Frequent use of a hair dryer, ironing, curling iron, aggressive styling products damage hair and leads to its thinning and brittleness.
• Diets: Restrictive diets, especially those that exclude important groups of products, can lead to a deficiency of nutrients and problems with hair.

In these cases, the addition of vitamins and minerals in the form of dietary supplements can provide significant support for hair health. However, it is important to understand which vitamins and minerals are necessary, in what dosages and how to take them correctly in order to get maximum benefit and avoid unwanted side effects.

2. Key vitamins and minerals for hair health: Scientific review

Various vitamins and minerals play a key role in maintaining hair health. Consider the most important of them:
