Review (5/5): Buy this NOW.
I absolutely LOVE this shampoo (and conditioner too)! This is the very best sulfate free shampoo on the market because it actually lathers. I have very thick and long hair that I dye regularly. I'm also allergic to synthetic fragrances. Since using this product, the itchy rashes have gone away, and my hair dresser was impressed by how baby soft my hair had become (again, conditioner too). It took only a month to go through this stuff, so save a few bucks where you can because it's sooooo worth it.
