I have blond hair.  Blond hair lacks dark pigment eumelanin
I have dark hair (well, before it turned gray), so I guess that meant I had lots of eumelanin?
You're right BRown hair is characterized by higher levels of eumelanin and lower levels of pheomelanin.
I just know that now that I am gray, my stylist says I have "non-pigmented" hair.  I wonder why hair changes color for young kids.  My son born with red, now dirty blonde.
well, you're levels of melanin can vary over time.  Its possible to have hair folicles of different colors on the same person.
I guess my son has hair follicles of different colors then.  Does genetics play a part in hair color?
yes, and hair colors are also associated with ethnic groups.
