Inverse androgenic alopecia.

A man in his 50s presented to our clinic with obvious progressive hair thinning in the occipital area below the creeping alopecia crown vertex accompanied by the typical Hamilton-Norwood pattern of male androgenetic alopecia (MAGA) hair loss. Based on his clinical features, trichoscopy findings and histological features, as well as his good response to conventional anti-MAGA therapeutic drugs, such as finasteride and minoxidil, a novel isotype of MAGA, named inverse-MAGA, was first identified, and this isotype should be widely evaluated in future studies.
