Most male pattern baldness is seborrheic alopecia or androgenetic alopecia. The clinical manifestation is a receding hairline and progressive thinning of the hair on top of the head, with oily scalp and itchy scalp discomfort in the early stages of hair loss. The cause of hair loss is mainly related to high androgen secretion or the patient’s hair follicles are sensitive to androgens. Because the hair follicle is a receptor for androgens, it is easy to cause hair loss under the action of androgens. In addition, the disease has a genetic tendency, and patients with hair loss have a higher chance of passing it on to the next generation. At the same time, people’s daily diet, such as like spicy and stimulating diet, stay up late, and people who are engaged in long-term mental work, are prone to hair loss.
