Accepted Answer

Hair color is determined by the type and amount of melanin produced by melanocytes located at the base or papilla of the hair follicle. Different variations in hair color reflect differences in the type and amount of melanin produced. Other factors such as age and air bubbles in the medulla of the hair shaft can also affect hair color, but they are not the primary determinant.
