Here, we present a case of repigmentation of hair which developed during interferon 2a (IFN- 2a) and ribavirin treatment of hepatitis C. The most frequently encountered change in hair color related to IFNs is hypopigmentation [1–3]. We discuss this paradoxical situation of hyperpigmentation which has not been reported previously.eninfo:eu-repo/semantics/closedAccessHair PigmentationHepatitis CInterferonRibavirinArticle10.1159/0000864552112171172160881722-s2.0-23844518444Q1WOS:000231388900025Q2
