London: Scientists have identified a hair-loss protein that could potentially pave the way for a cure for male baldness.
Tests were carried out on tissue from the scalps of a group of men with male pattern baldness, known as androgenic alopecia (AGA).
The results showed bald areas had levels of the protein PGD2 three times higher than hairy areas, the journal Science Translational Medicine reports.
There are already 10 drugs available that can block the receptor that allowed PGD2 to work, which could help researchers develop a treatment in the form of a cream or ointment, according to the Telegraph.
George Cotsarelis, professor at the University of Pennsylvania, who led the study, said: “Our findings should lead directly to new treatments for the most common cause of hair loss in men, AGA.
“The potential for developing these compounds into topical formulations for treating AGA should elicit great interest moving forward.”
