In humans a patient suffering from hair loss would give scientists their own progenitor cells, and the hair follicles would be grown in a lab. Once fully grown, they could be transplanted directly onto the patient. Cheng-Ming Chuong, senior author of the research, said: “Normally, many aging individuals do not grow hair well, because adult cells gradually lose their regenerative ability.“With our new findings, we are able to make adult mouse cells produce hair again. In the future, this work can inspire a strategy for stimulating hair growth in patients with conditions ranging from alopecia to baldness.”

The general term for hair loss is alopecia. There are many types of hair loss, including male and female pattern baldness, scarring alopecia and alopecia areata. Pattern baldness affects about half of all men by 50 years old. It starts with a receding hairline, and then progresses to a thinning on the crown and temples.Scarring alopecia is normally caused by other conditions. The condition involves the hair follicles becoming completely destroyed.

Coin-sized patches of baldness is usually a sign of alopecia aerate. It’s caused by problems with the immune system.
