During the process of skin regeneration following a skin injury, de novo hair follicle regeneration is initiated after wounding; however, these regenerated hairs are mostly unpigmented. The activation of epidermal melanocyte stem cells and their differentiation into regenerating hair follicles have been shown to be necessary for the pigmented hair regeneration after wounding. To determine the role of flavonoids in the regeneration of pigmented hairs, we applied the candidate flavonoids to the regenerating hair follicles after wounding and identified the flavonoid species that maximally induced pigmented hair regeneration. Flavonoids with two OH groups in the B-ring, such as sterubin, luteolin, and hydroxygenkwanin, showed promising effects in regenerating black pigmented hairs, while those with one OH group in the B-ring showed no significant change. Thus, flavonoids with two OH groups in their B-ring could be studied further as potential wound healing agents with the ability to regenerate pigmented hair.
