Oily hair very quickly becomes “oily” after washing , i.e. look dirty and messy, dull and fall out more intensely than normal hair. Oily hair often goes side by side with oily skin , because both are a consequence of the increased activity of the sebaceous glands of the skin.
The cause of increased fat content of hair can be not only a violation of the normal activity of the sebaceous glands, but also improper care of hair, for example, excessively frequent and excessive rubbing of various oily and nourishing masks .
Mixed hair is usually understood as a hair type , in which at the roots they oily quickly and at the ends remain dry, split.
This type is most characteristic of long hair : the natural fatty grease produced by the sebaceous glands of the scalp is simply not enough for the entire length of the hair.
