Thanks, Listy. I've found Matrix a reliable brand over the years so I shouldn't have been surprised that So Silver worked for me.
Marci, I don't know, sorry. I do a conditioner only wash every other day with just Paula's Choice conditioner. I must say the shampoo leaves my hair very soft, and I don't use conditioner when I shampoo. The reviews I read led me to expect it to be drying, but so far that hasn't been so. Perhaps a toner followed by a conditioner would be better for you. I know practically nothing about hair products though, so it's probably best to ignore me!
