9 – Grey hair can be treated with medicines?
The hair follicle has two kinds of cell systems. One for creating new hair and second for supplying pigment to the growing hair follicle. Greying results when the pigment cells have died or stopped functioning due to UV exposure, pollution, accumulation of free radicals, stress, nutritional deficiencies and these cannot be regained with any known medicine to date. Many imperical treatments are tried. One is as ineffective as the other.
