Am J Contact Dermat. 1997 Sep;8(3):177-8. doi: 10.1016/s1046-199x(97)90103-2.


Koilonychia is a nail disorder well known to accompany certain systemic diseases, but it can also be caused by external factors. We report two cases of occupational koilonychia in hairdressers caused by the toxic effect of chemicals used in permanent wave. Hairdresser's koilonychia has been seldom reported, but may be common.
