Grey hair during ageing is the result of exhaustion and loss of melanocyte stem cells, says Sturm, so a similar mechanism could be at play with stress-related greying. “Certainly stress can affect the stem cells and one way to lose or go completely grey is to lose your stem cells quicker,” he says. The discovery could also lead to treatments for conditions such as vitiligo — depigmentation of the skin — and to prevent hyperpigmentation, which is too much pigment in the skin. “If we can know more about how melanocytes migrate from hair follicle area to the epidermis, we may get the ability to promote this process for the treatment of hypopigmentation disorders,” says Ito. “Our results suggest that melanocyte migration from the hair follicle to the epidermis may partly contribute to skin pigmentation, thus inhibition of this migration process may be a novel approach to prevent UV induced hyperpigmentation, or post-inflammatory hyperpigmentation commonly seen after surgery.
