Causes of Gray hair


While a few ladies gladly sport a silver mane, numerous others face the appearance of new silver hairs with fear. The uplifting news in the event that you fall into the last class: Scientists are working diligently on the best way to forestall them. Things being what they are, what do scientists realize that you don't? 


Alright, nothing unexpected here. Dermatologists call this the 50-50-50 principle. "50% of the populace has about half silver hair at age 50," says Dr. Anthony Orb, educator of dermatology at Stanford University. Also, similar to skin, hair changes its surface with age, says Dr. Heather Foolery Lloyd, chief of ethnic healthy skin at the University of Miami School of Medicine.
