Collagen may help age-linked hair loss

A team of researchers, including Japanese scientists, has discovered the mechanism behind hair loss associated with aging, a finding that could pave the way for new ways to treat baldness.

In the study led by Tokyo Medical and Dental University’s Emi Nishimura, the team determined that type XVII collagen, found near hair follicle stem cells beneath the scalp, is the key to thinning hair.

They identified this particular collagen as responsible for damaging the DNA of hair follicles. As the collagen disappears with age, the follicles shrink, causing hair loss.
