Balding Hair Today It's thought that 50 million men and 30 million women suffer from complete balding or partial hair loss in the US alone. However, a promising new treatment looks set to offer a new way to spur regrowth.

They then grouped themselves into the form of polarized cysts, which in turn gave way to la
