Family genetic history is the direct factor leading to adolescent hair loss. Generally speaking, men are more likely to suffer from hereditary alopecia. Men are genetically dominant and women are negative. However, women do not have baldness, and most of them show sparse hair.

2. Drinking and smoking

Drinking and smoking is also the cause of adolescent hair loss, and it is easy to develop bad living habits, especially smoking and drinking too early. Liquor can easily cause teenagers' scalp to generate hot air and secrete too much oil. Scalp is prone to hair loss in humid environment, which is an important reason for adolescent hair loss.

3. Preference for heavy taste

Many hair friends like to eat sweet, salty, greasy and spicy food, all of which are acidic. Long-term diet will make acid toxins in food destroy hair follicles through blood, leading to hair follicle necrosis and hair loss in adolescents.

Step 4 go on a diet to lose weight

There are also many teenagers who go on a diet to lose weight in order to keep fit. What I want to tell you is that long-term dieting will lead to insufficient nutrition in hair follicles, which will lead to hair softening and eventually falling off.
