Hair loss is classified into physiological and pathological, and the common ones are baldness and seborrheic alopecia. The hair loss area is round or oval in size, the scalp is bright and free of inflammation, the color is normal, the pores are clearly visible, and the hair loss boundary is clear, the lighter the size of a soybean, the heavier the size of a silver dollar. Some eyebrows, beard, pubic hair, sweat hair, etc. can be lost, which is called general baldness. Seborrheic alopecia is mostly seen in men, so it is also called male pattern baldness or androgenic alopecia. This kind of alopecia mostly appears after puberty, and it is most common around the age of 40. Seborrheic alopecia is accompanied by scalp fat overflow, dandruff and itchy scalp. There are many causes of baldness, but an important one is the mental factor or emergency. Seborrheic alopecia is mostly thought to be related to androgen overproduction. Hair loss is annoying, not only affects the beauty, but also seriously affects work, study, marriage and family, etc. It really makes people have a sense of helplessness. In the end, whether hair loss can be cured, the answer is yes, but no matter what methods or drugs should be adhered to more than six months, the treatment of hair loss is most taboo three days to fish and two days to sunbathe. Here we would also like to say that there seems to be no need to treat physiological hair loss in those who are too old. The treatment of hair loss should be treated separately and chosen according to different situations such as: oral and topical medications, traditional Chinese medicine, acupuncture and physiotherapy, phototherapy, hair transplantation and psychotherapy.
