Melanin in the skin makes it darker , and to quote my source:
" Hair contains pigments that are vulnerable to chemical
modification by a process called photobleaching. Rearrangements in the pigments molecular structure changes the way light is
absorbed and reflected. A similar effect can be caused by
chemical bleaching by the hair stylist or from chlorine in a
swimming pool by a process called chemical bleaching. The sunmay also change the water content of the hair and this can causesubtle color changes by changing the relative density of the
color pigments.

Your hair does not need this function, and so it does not have this pigment.
