Background and Objective: Hair whitening is among important cosmetic problems in both genders but more annoying between women which necessitates more research about hair repigmenting methods or probable therapeutic drugs. The objective of this research was to review the mechanisms of hair pigmentation as well as the drug-related hair repigmentation.

Methods: In this review article, we searched PubMed, Medline and Google scholar databases and reviewed all related articles in this area (hair repigmentation) since the reversal of canities has been an important cosmetic concern many years ago.

Results: No reports of changes of hair color have been identified with lamivudine in the present research. Herein can be reported as the first case of hair repigmentation following the use of lamivudine.

Conclusion: We reported a case of hair pigmentation with lamivudine for the first time that could be a desirable drug-induced side effect, also review all related articles about hair repigmention or reversal of canities. By research on probable mechanisms of drug-induced hair repigmentation, we may achieve a therapeutic strategy of hair graying as an important and highly prevalent cosmetic concern.
