Detailed explanation-1: -White or Gray Hair Hair that lacks melanin pigments become white. Thus, white hairs completely lack both eumelanin and pheomelanin pigments. White-haired people reflect light due to the optical activity of the color.

Detailed explanation-2: -If the receptors are inactive or blocked, they produce pheomelanin, the pigment responsible for orange or red hair. Jet-black hair has large numbers of tightly packed eumelanin. Red hair has large numbers of tightly packed pheomelanin. Blonde hair has both types of melanin, but in very small amounts and loosely packed.

Detailed explanation-3: -Melanin deficiency is associated with vitamin deficiency. That’s why you need to increase your vitamin intake through your food or vitamin supplements. Vitamin A, C and B12 are the most needed vitamins to increase the melanin production in your hair.
