Hair dietary supplements: which really work?

Chapter 1: Understanding the basics of hair health

1.1. Hair structure and its life cycle:

Healthy hair is the result of a complex interaction of internal and external factors. To understand what additives can be useful, it is necessary to understand the structure of the hair and its life cycle. The hair consists of three main layers:

• Cuticle: The outer layer formed by flat, overlapping each other, like a tile on the roof. A healthy cuticle is smooth, reflects light and protects the inner layers of the hair from damage. The damaged cuticle looks rough, dull and leads to brittleness and split ends.
• Cortex: The main layer that makes up the most part of the mass of the hair. It contains keratin, protein, which provides strength and elasticity. The cortex also determines the color of the hair due to the pigment of melanin.
• Medulla: The inner layer, which is not in all hair (often in thick hair). Its function has not been fully studied.

The life cycle of the hair consists of three phases:

• Anagen (growth phase): The longest phase that lasts from 2 to 7 years. During this period, the hair is actively growing. About 80-90% of the hair on the head are in the anagen phase.
• Katagen (transition phase): It lasts about 2-3 weeks. At this time, hair growth slows down, and the hair follicle decreases.
• Telogen (Phase Salm): It lasts about 3 months. During this period, the hair does not grow and remains in the hair follicle until it pushes a new growing hair. About 10-20% of the hair are in the bodyogen phase.

1.2. Hair health factors:

The health of the hair is affected by many factors, both internal and external:

• Genetics: A genetic predisposition plays an important role in determining the type of hair, their density and a tendency to loss.
• Hormonal background: Hormonal changes, such as pregnancy, childbirth, menopause, thyroid diseases, can significantly affect the height and condition of the hair.
• Nutrition: The disadvantage of nutrients, such as protein, iron, zinc, vitamins of group B, can lead to loss, brittleness and slowdown in hair growth.
• Stress: Chronic stress can negatively affect the health of the hair, causing their loss (heterogene alopecia).
• Diseases: Some diseases, such as autoimmune diseases, infections, diseases of the scalp, can lead to hair loss.
• Medication: Some drugs, such as anticoagulants, antidepressants, chemotherapeutic drugs, can cause hair loss.
• External factors: Excessive use of thermal tools (hair dryers, ironing, curling iron), chemical treatment (staining, curling), improper hair care can damage hair and lead to their fragility and loss.
• Age: With age, the hair becomes thinner, weaker and slower grows.

1.3. Signs of unhealthy hair:

Recognition of signs of unhealthy hair is the first step to solving the problem. The main features include:

• Hair loss: The loss of more than 100 hair per day is considered excessive.
• Grightness and dryness: Hair breaks easily, seize on the ends, becomes dry and dull.
• Slow growth: Hair grows slower than usual.
• Thinning of the hair: The hair becomes thinner and less thick.
