First - BEAUTIFUL!!!
second-do you work at a fest or just like the garb? Hubby and I both grew up working MRF (minnesota's fest)
third- My Great-grandmother was a feww weeks shy of 90 when she passed, she had knee length silver and black hair, and she would only pull it up to cook, or when it was very windy. She looked fabulous, everyone complimented her on her hair, she loved it - granted it also took me two hours to brush and comb it for her, but I felt honored.
Fourth-with how black your hair is, it would have to be bleached out some for any color to lighten it up, please don't.
Woman can have whatever hair they choose whenever they choose, even if they have to go out and buy some!
