Identification of titanium dioxide on the hair shaft of patients with and without frontal fibrosing alopecia: A pilot study of 20 patients

Abstract

Frontal fibrosing alopecia (FFA) has increased markedly in incidence since it was first reported in 1994. A possible role of cosmetic ingredients has been suspected, especially UV blockers, since these were added to products in the late 1980s. Daily, year‐round use of facial moisturizers, most of which contain a sunscreen, has been associated with FFA in both women and men, An additional large study has reported that the use of facial sunscreens is the only common risk factor for FFA in both males and females. Patch testing in FFA patients shows a high prevalence of sensitization to cosmetic ingredients but not to a specific culprit, possibly indicating that these patients utilize more cosmetic products than the general population.
