After treatment, baldness usually starts to grow new hair in about 1-2 months, depending on the individual.
Alopecia areata is a common skin disease that can manifest itself as limited hair loss in a round or round-like shape, varying in size in diameter from about 1 cm to several cm in size, with clear borders and a normal scalp at the hair loss area, with no self-perceived discomfort symptoms. In the active phase, the hair at the edge of the hair loss area can be pulled out by gentle tugging. The treatment is mainly localized, with topical application of strong corticosteroid ointment or subcutaneous injection of corticosteroid medication. For lighter patients with limited hair loss, new hair growth can start within 1 month, while for patients with larger hair loss areas, it may take up to 2 months or even longer to start growing hair.
In addition, patients with alopecia areata need to pay attention to maintain a good work and rest schedule and avoid excessive mental stress or overwork.
