Specific features:
The hair is greasy, and oil stains have appeared on the roots of the hair the next day after shampooing, and the scalp accumulates on the roots like thick scales, which is easy to itch. Because of excessive sebum secretion and greasy hair, it is mostly related to hormone secretion disorder, heredity, mental stress, excessive combing and frequent eating of high-fat foods. These factors will increase oil secretion.
People with sparse hair are more likely to have oily hair, because each sparse hair has smaller circumference, more hair follicles per unit area and more sebaceous glands, so it secretes more sebum.

Solve the problem of hair oil:
1, clean correctly
The scalp itself is constantly secreting oil, but different people have different degrees. Don't worry, the more you wash your hair, the more oily it gets. In fact, if you don't wash your hair, it will get more and more oily. Excessive oil accumulation may also block hair follicles, causing more serious consequences such as hair loss.
Don't touch your hair with your hands.
Especially after eating greasy food or cooking. Remember to put your hair behind your head when putting on makeup to avoid greasy cosmetics sticking to your hair. In the process of makeup, your hands are usually covered with cosmetics. Don't touch your hair with your hands at this time. Comb your hair with a clean comb, not your fingers.
3, light diet
When the human body ingests too much oil, it has to secrete some oil from the skin because of its limited digestive function. The most common places are scalp and face. Therefore, reducing the intake of oil properly has a positive effect on reducing the oil secretion of scalp and face.
