Hair follicular keratinocyte stem cells (HFKSC) which provide a functional niche for melanocyte stem cells (MSC) are the primary target of hair graying. However, little research has been done on anti-hair graying medicines targeting HFKSC. We focused on Eriodictyon angustifolium (Ea), which reduces human hair graying when applied topically. To investigate the protective effect of dietary Ea tea (EaT) on hair pigmentation, we used an acute mouse model of hair graying that mimics X-ray-induced DNA damage associated with age-related hair graying. Our results suggest that dietary EaT maintained the niche HFKSC function against X-ray-induced DNA damage and hair graying. These results indicate that dietary EaT may prevent age-related hair graying and serve as an anti-hair graying herbal medicine.
