This is pretty thick stuff and you probably won't like it if your hair is thin or if you're looking to add volume. But it's great for me - my hair is not quite curly but not all the way straight, so I have long fought with it to get it smooth and straight rather than just kind of "puffy." I just started using this shampoo and conditioner but noticed a major difference within the first few days. It really changes my hair's texture and makes it a lot easier to get the smooth, straight look that was such a struggle for me to achieve before. I find that I don't even need really need straightening cream anymore. It also makes my hair really soft, and I love the smell. I do follow the directions to keep the conditioner in for 3 mins, so try it after doing the same. Good luck!
