I've avoided swimming in a chlorinated pool for oh, about 4-5 years now because my hair is always highlighted. It's naturally very dark brown, but I have dark-blonde/lighter brown highlights in it right now and I have to swim in a triathlon. I'm scared that my hair will turn green. My hairdresser recommended 2 products by Joico called Phine & Resolve, but when I went shopping, I could only find a chelating shampoo from Joico and an intensive masque, which were sold as a set. Apparently they replaced Phine & Resolve or something. Has anyone tried this stuff (the newer products)? Any other suggestions?
