I have extremely thick hair that's neither straight nor curly nor particularly wavy. It's kind of a mix depending on the day and it's consistently coarse and dry, especially at the tips. After washing with this shampoo (I don't use conditioner really) my hair is really 100% softer. If your hair is thinner, I wouldn't recommend this shampoo as it is fairly heavy and creamy, but for thick-haired girls it works well. I find it is especially nice because I do only wash my hair twice a week, sometimes three if necessary. I'll wash my hair on a Tuesday and my natural oil will only start to be grimy by Saturday, and I'll then wash my hair. Even more, first-day hair tends to be fluffy and frizzy and this shampoo gives my hair some life and bounce without being overly crazy. To top it all off, it's a great bargain.
