Most of the acquired non-scarring baldness can grow hair again after active diagnosis and treatment, congenital baldness and acquired scarring baldness, usually can not grow hair. Acquired non-scarring baldness caused by patchy baldness, androgenetic alopecia, etc. can be treated with drugs such as finasteride, spironolactone, minoxidil, and glucocorticosteroids (e.g., prednisone, betamethasone, prednisolone, etc.), and most of them can grow hair again after active treatment. Congenital baldness and acquired scarring baldness have no effective treatment because the hair follicles have been damaged, and thus generally cannot grow hair again. People with baldness need to develop good daily habits, pay attention to scalp cleanliness, pay attention to hair protection. At the same time, they should keep a good mindset and wear a wig to change their appearance and enhance their self-confidence.
