I color my own hair (non permanent color from loreal nutrise something) and use shampoo and conditioner for color treated hair. I've been using Herbal Essences Color me happy though I've used tresseme, suave, salon selectives and Redkin (that was a Christmas present from my mom) all for color treated hair, so far, but I was at target and looked at the ingredients on the shampoo bottles> I read that sulfates are bad for colored hair, they strip the hair down or the color out. But every shampoo has it, even the ones for color treated hair. So unless I'm missing something, does it really matter what shampoo ya use for hair that is colored? Is it all just an advertisement gimmick to get people to buy it? Seems confusing to me.
