An osteoporosis drug may offer a novel way to stop hair loss and help cure baldness.
Osteoporosis is a condition in which bones become weak and vulnerable to breaking.
WAY-316606 targets a protein called SFRP1, which suppresses hair growth.
Big questions remain, though, and it's still far from human use.
Currently, only minoxidil and finasteride are FDA approved medicines for hair loss.
