How to choose a dietary supplement for hair growth: expert tips

I. Understanding the basics: what is dietary supplements and how they affect the hair

Dietary supplements, or biologically active additives, are concentrates of biologically active substances designed for direct intake with food or introduction into food products. They are not drugs and are not intended for the treatment of diseases. However, with proper use, they can have a positive effect on the general state of health, including the condition of the hair.

Hair, like any other organs and tissues of the body, needs certain nutrients for normal growth and development. The deficiency of these substances can lead to various problems, such as hair loss, growth, dryness, brittleness and dullness. Bades can help make up for the lack of these substances and improve the condition of the hair.

A. The structure of the hair and its life cycle

To understand how dietary supplements can affect hair growth, it is important to know the structure of the hair and its life cycle. The hair consists of two main parts:

  1. Hair rod: The visible part of the hair, which consists of three layers:
    • Cuticle: The outer layer consisting of flat flakes that overlap each other. The cuticle protects the hair from damage and gives it shine.
    • Cortex: The middle layer, which is the main mass of the hair. Cortex contains melanin, which is responsible for hair color.
    • Medulla: The inner layer, which is not present in all hair. The function of the medulla is not fully studied.
  2. Hair follicle: A bulb located in the scalp from which the hair grows. In a hair follicle, cell division processes occur, which provide hair growth.

The life cycle of the hair consists of three phases:

  1. Anagen (growth phase): It lasts from 2 to 7 years. During this phase, the cells are active in the hairline follicle, and the hair grows.
  2. Katagen (recression phase): It lasts about 2-3 weeks. During this phase, hair growth stops, and the hair follicle is compressed.
  3. Telogen (Phase Salm): It lasts about 3 months. During this phase of the hair, it stops growing and is held in a hair follicle. At the end of this phase, the hair falls out, and in its place new hair begins to grow.

Normally, about 90% of the hair are in the anagen phase, 1% in the catagen phase and 9% in the heterogene phase. Violation of this ratio can lead to hair loss.

B. Causes of hair problems that dietary supplements can affect

There are many reasons that can lead to problems with hair. Some of them:

  1. Genetic predisposition: Heredity plays an important role in determining the type of hair, their density and a tendency to fall out.
  2. Hormonal changes: Hormonal changes, such as pregnancy, childbirth, menopause or thyroid disease, can affect the height and condition of the hair.
  3. Inal meals: The deficiency of vitamins, minerals and other nutrients can lead to hair loss, deceleration of growth and deterioration of their condition.
  4. Stress: Chronic stress can negatively affect hair health.
  5. Incorrect hair care: Excessive use of thermal instruments, aggressive chemicals and tight hairstyles can damage the hair and lead to its loss.
  6. Scalp diseases: Some diseases of the scalp, such as seborrheic dermatitis, psoriasis and fungal infections, can lead to hair loss.
  7. Medicines: Some drugs, such as antidepressants, anticoagulants and chemotherapeutic drugs, can cause hair loss.

Bades can be useful in cases where hair problems are associated with malnutrition, stress or hormonal changes. They can help make up for a lack of nutrients, reduce stress and normalize hormonal balance. However, it is important to understand that dietary supplements cannot cure a genetic predisposition to hair loss or scalp disease. In these cases, you must consult a trichologist.
