Hi, loss of hair colour is due to a gradual decline in the production of a pigment, melanin, in the hair bulb. White hair has no pigment, and gray hair has some pigment left. 200 mg of PABA or 200 mg of
calcium pantothenate are proven to give benefit in prevention of premature greying.. kindly consult your physician before u start medication..
