In daily life, we find that some people’s hair is curved like a wave, but some people’s hair is firm and straight. People are accustomed to distinguishing according to some characteristics and standards of hair.
For example, according to the intuitive appearance of the hair, the hair can be divided into three types: straight hair, wavy hair and curly hair.
- Straight hair, including hard straight hair, straight hair and shallow wave hair, etc.;
- Wave hair, including wide wave hair, narrow wave, hair waves;
- Curly hair, including 5 kinds of curly hair, curly hair, tight curly hair, loose spiral and tight spiral hair.
The color of hair is diverse, black, brown, yellow, white and red, etc. It is affected by the amount of melanin contained in the pigment cells of the hair follicle matrix, the presence or absence of bubbles and the structure of the hair epidermis. When it contains many melanins, it is black, when it contains less melanin, it is gray. When there is no melanin, it is red when it contains iron pigment. When there is bubble, it is lighter. If there is no bubble, it is darker. The difference between these hairs is determined by heredity and race. Caucasians are in the form of straight hair, spiral hair, wavy hair and curly hair. The color ranges from light yellow to black, and the cross-section is oval. The black hair is curled, black, and has an oblate cross-section. The yellow man’s hair is straight and not curled, and the hair has a round cross-section, black, and is a cylinder.
