Hair cut

Scientists found a way to grow new hair. Method: "The researchers made relatively large wounds on the backs of adult mice, and found that if a wound reached a certain size new hairs formed at its center, with the skin undergoing changes mimicking stages of embryonic hair-follicle development." Theory: The wounds activate dormant embryonic mechanisms that reprogram skin stem cells to make hair follicles. The good news: We can cure baldness! The bad news: ... through head wounds.
