I started going gray at 16 (which was when I started dating my husband..should that have told me something). Now at 57 it is a silver/gray. I colored it at home for years. The last time (about 5 years ago) it turned several colors..purple..then orange and then pink.. I went to the hairdresser and she tried to fix it.. colored it 3 times to get it brown and then it two weeks it turned ash blonde which was the color it was supposed to be in the first place. Never again. Going to work with pink hair was the laugh of the office for quite some time. I guess I have earned each and every gray strand one of them, 40 years of marriage and 3 grown sons.
