I fared with this shampoo as well as another reviewer: I too have natural curls, at the first application they began to feel like straw (when wet!). After shampooing they were almost unkämmbar and very dry. Even after repeated use, this impression did not change. Have been for some time ceased to use shampoos with silicone (or initially even use a shampoo that is to rid the hair of residues), but a similar bad result I have ever experienced in any silicone-free product. Too bad, otherwise I'm actually a big fan of Alverde.
