We present the case of a patient in whom active new hair growth occurred around a wound after healing. This very rare phenomenon has not previously been reported in the literature. We postulate that, after the epidermis and hair follicles have been damaged by wounding, it is possible for them naturally to heal and repair if provided with an appropriate chemical and physical microenvironment. This hypothesis may inspire new thinking in the management of alopecia, tissue engineering and the regeneration of other organs.
