The hair is a flexible, about 0.1 mm thin horn thread of great strength and elasticity. It is formed in the hair bulb.
The hair shaft is the part of the hair that is visible from the outside, i.e. what we generally call „hair“. The structural structure of the hair shaft remains stable.
The sebaceous gland supplies the hair shaft with sebum and thus gives the hair its healthy shine.
The hair follicle is a tubular bulge of the skin, the place where the hair is formed.
The hair bulb is the lowest part of the hair follicle. There the hair is created by the formation of new cells. The hair is pressed upwards out of the skin piece by piece – it grows.
The nutrients that are important for hair growth reach the hair bulb directly through the blood vessels.
