Dihydrotestosterone alopecia is mostly classified as androgenetic alopecia and is controlled by topical medication, oral medication, and surgery. Androgenetic alopecia is progressive baldness that occurs during and after puberty and usually leaves no scar. 1. Topical medication: Minoxidil application is a peripheral vasodilator, which can be used topically to promote hair growth; if there is fungal infection, it can also be treated with topical antifungal medication, such as ketoconazole lotion. 2. Oral drug treatment: male androgenetic alopecia patients, oral finasteride treatment; female androgenetic alopecia patients, oral cyproterone to fight against androgens, to alleviate the symptoms of hair loss, acne, hirsutism, etc.; female patients can also take oral spironolactone, to reduce the loss of hair. 3. Surgical treatment: For severe hair loss, hair transplantation can be performed to transplant hair follicles from areas that are inherently insensitive to androgens into bald areas to improve the appearance of hair loss. It is recommended that after diagnosis, patients should strictly follow the doctor’s instructions to use medication, and should not blindly use medication on their own to avoid adverse reactions and delay the condition.
