Androgenetic alopecia is reversible after regular treatment, but it is a progressive aggravation process. Early treatment is recommended, and treatments include systemic treatment, topical medication, hair transplantation, and other methods. 1. Systemic treatment: oral finasteride is suitable for male patients. Oral spironolactone and cyproterone are suitable for female patients, especially for patients with acne and hirsutism. 2. Topical medication: common topical medication is minoxidil, which has adverse effects such as hirsutism and contact dermatitis. 3. Hair transplantation: Separate out the hair follicles from the androgen-insensitive area (usually from the back of the occipital scalp) and transplant them to the bald area, follicular unit hair transplantation technique is one of the common methods. 4. Other: low energy laser treatment can improve the microenvironment around the hair follicle, as an auxiliary treatment means, when other treatment means are ineffective, the patient can use wigs, hair pieces, etc. to cover. Patients with androgenetic alopecia should not use medication on their own, and should go to the hospital in time and standardize the treatment under the guidance of the doctor.
