The reviewer below me did an excellent review so I won't go into repeated details but I'll just highlight the things I love about this particular shampoo. I have pretty fine hair that's been through a lot of chemicals over the past years (perms, magic straight, highlights, at-home dyes, etc). I've done some decent amount of trimming but my ends are still dried with visible split ends (I hate having short hair so I refused to cut off all my dead ends). Anyway, my hair tends to feel worse during the winter and feels very dry. I also experience some flakes from dry scalp which is very unpleasant/embarrassing. I asked on the hairboard what I can do to remedy this problem and they recommended Denorex. I went to Wal-Mart and easily found it on the shelf next to head&shoulders and selsun blue (move over, denorex is so much better!) I have tried both h&s and s.blue and ended up disappointed. Today is only my second day of using denorex 2-1 extra strength anf I absolutely love it!!! (The cool things about this shampoo is that it is silicone and sulfate FREE! + there's a built in conditioner hence the name but I still use a separate conditioner after) There is no more static in my hair, my hair is not tangly, nor does it flake or dry!! This is a miracle product. After using this shampoo, I use my tresseme naturals volume conditioner and my hair is shiny, feels healthy, and slippery (in a good way). I purchased a decent sized bottle for 7 dollars at Wal-Mart. I will buy again and again.
