I saw shampoo and Jamie Lee Curtis both mentioned in this thread and just thought I'd throw it out there that in a magazine interview I read a while ago she said she used Phytargent Whitening Shampoo. She raved about it. I looked into it as I had stopped coloring and was letting my grey show through. It's a bit pricey, but I never ended up buying it since shortly thereafter my youngest son was getting upset that I was getting "old hair"!
