Detailed explanation-1: -The range of colors produced by melanins is limited to shades of yellow, brown, red, and black. Grey hairs contain only a few melanin granules, spread out through the hair. White hairs contain no melanin at all: their whiteness is an optical effect, due to the way they reflect the light.
Detailed explanation-2: -Studies suggest that upping your intake of certain nutrients could increase melanin levels. It might even increase the amount of melanin in people with fair skin types. There are no studies directly proving ways to increase melanin.
Detailed explanation-3: -Melanin is brown, non-refractile, and finely granular with individual granules having a diameter of less than 800 nanometers. This differentiates melanin from common blood breakdown pigments, which are larger, chunky, and refractile, and range in color from green to yellow or red-brown.
