My hairdresser and a waitress where we eat asked if I'd put something on my hair to lighten it. Well, my hairdresser should know as she would have put it on. I suggested that I'm getting grayer but neither of them thought it was that. I guess it's exposure to the summer sun. I seriously try to avoid that because of the melanoma I had several years ago as well as the brown spots on my hands, arms, and legs.
