Dr. Oz: Does Hair Pigment Change From the Sun?

Doctor Oz was asked on Facebook why hair pigment changes over time and if it could be from sun exposure.

Dr. Oz said that your body will change and your hormones will change as you get older… and these same hormones change the pigments in your hair.  Also, the sun will bleach your hair in the short term, but in the long term the sun actually darkens the pigment of your hair!
