Whether hair can still grow on the top of the head with alopecia areata, the first step is to clarify the diagnosis.
Commonly, androgenetic baldness, or seborrhoeic alopecia, is manifested by unconscious thinning and thinning of the hair on top, which gradually worsens, and men also experience a receding frontal hairline. If treated promptly, the density of the hair can be increased to varying degrees. The second is patch baldness, which can occur suddenly as a round or oval bald spot in any area, including the crown of the head.
Alopecia areata can heal spontaneously, but usually after more than 3 months; even those with severe hair loss can return to full normal after appropriate medication. However, there are also many scarring alopecia that occur on the crown of the head, such as flat hair moss, discoid lupus erythematosus and central centrifugal scarring baldness, where the hair cannot regrow if not treated promptly.
