The hair has a life cycle, it falls out so that a new one is born, but in many cases this step is not met.
This fact occurs in a higher percentage in men over 50 years, while in men of 30 years the percentage is lower.
When 50 to 150 hairs a day fall out, the loss is considered normal.
Alopecia and baldness are phenomena that refer to hair loss and can be partial or total.
Alopecia can vary in both degree and pattern, especially in the case of men. Most of them suffer from androgenic alopecia.
