I have a bit of a hair obsession, as you can tell. My hair is in rough shape, so I'm trying everything I can to help it. I'm confused about sulfates. Are they more damaging to hair, or not? Here http://thebeautybrains.com/2008/07/28/3-ways-to-protect-your-hair-from-heat/ you say, "You might also consider sulfate free shampoos that use milder surfactants, like decyl glucose, because they are less likely to dissolve the precious 18-MEA." So does that mean sulfates are more damaging? I had always had the opposite impression. I feel I need to use a shampoo for extra body (i.e., sulfate shampoo) because I have fine hair and moderate sebum production, and I also use conditioning styling products that can build up. My hair goes flat at the drop of a hat (sorry for the rhyme). But I also have damage from professional highlighting, and don't want to break down my hair any more. Should I worry about using sulfates, as long as I condition well?
