There are many reasons for hair loss, such as heredity, spirit, stimulation, seasonal climate, long-term lack of vitamins in the body, malnutrition, endocrine disorders, work and study pressure, lack of sleep, environment and so on.

If you don't lose a lot of hair, this is normal. Everyone loses about 40 hairs every day, just like animals lose their hair. If the number of alopecia exceeds 100, and for how long, check and treat it as soon as possible.

I suggest you choose a professional hair hospital first to check the subcutaneous hair follicles in the hair loss area. If there are subcutaneous hair follicles, you can use drugs to improve your hair. If the subcutaneous hair follicle is severely atrophied to necrosis, the hair loss area can only be improved by hair transplantation.
