Hair Structure

At this time, many young women in particular begin to think about how they can quickly remove the unwanted hair (hair) To understand the mechanisms of this depilation, one should first briefly consider the structure of the hair. The hair itself can be divided into hair shaft, the part that emerges from the skin, and the hair root within the skin. The hair root is surrounded by the so-called hair root sheath, which influences its growth.

The hair root originates from the hair bulb, into which blood vessels sprout, which supply the hair with all important nutrients and building materials for healthy growth. In addition, there are melanocytes. These are cells that produce the color pigment melanin, which is responsible for the color of our hair and also our skin.

This gives the visible hair its individual color. At the point where the hair emerges, the hair follicle becomes visible, which surrounds the hair shaft and further down the hair root. The secretions of glands flow into it.

These are mainly sebum and in some parts of the body also individual fragrances. The actual sweat glands are not closely associated with hair, which explains why people do not like to sweat any less on the hairless soles of their feet and palms than in the hairy armpits. The hair consists of cells that originate from skin cells.

These have lost a lot of water, but instead have long strands of certain proteins, the keratins, concentrated inside them. These give the hair stability. Certain chemical bonds, so-called disulfide bridges, give the hair its characteristic smooth or wavy shape (hair).

Hair Growth

The growth of the hairs proceeds in cycles. The first phase is the actual growth phase.First, a new hair root develops from the bulb, which spreads further upwards and finally becomes visible as a hair shaft. This phase depends on the body region and lasts longest for hair on the head with several years.

In the second phase, the transitional phase, the hair growth is interrupted by the hair follicle becoming narrower. The hair detaches itself from the bulb and moves to the surface. This is followed by the third phase, in which both the bulb and the bellows regenerate (hair).
