Solar protection by hair: More complex than it seems to be

摘要

To the Editor We read with great interest the article by Agi and Cohen1 recently published in JAMA Pediatrics. It offers a simple explanation of hair as a form of barrier occluding the skin to prevent solar damage; however, this article may be misinterpreted that long hair offers better solar protection than short hair. This is especially so because this article follows studies by Lesage et al,2 Chevalier et al,3 and Green et al4 that show epidemiologi-cal evidence of different incidences of melanoma in anatomical positions in girls and boys.
