TLDR Sunlight worsens hair loss; protect scalp.
This article from 20 years ago explores the relationship between androgenetic alopecia (AGA) and ultraviolet radiation (UVR). The authors suggest that AGA is a photoaggravated dermatosis that requires photoprotection. They also discuss the effects of UVR on hair loss, including acute telogen effluvium and follicular microinflammation. The authors propose that exposure to sunlight exacerbates AGA and other scalp disorders, and call for adequate photoprotection. The article highlights the importance of recognizing these disorders and properly diagnosing them, as they can often be confused with other scalp conditions.
