I used a travel size sample of this shampoo visiting my sister and I took the rest of the bottle home. It left my hair feeling soft and silky without feeling weighed down or greasy. I almost felt like I didn't need conditioner, which I always do because my hair is long and fine. My hair looked shiny and healthy even though it is color treated often. I spent the weekend outside, in the summer sun, so it passed the humidity test. I haven't used it for more than a couple days in a row, but for 2-3 days, my hair felt amazing.
