I have extremely fine hair which gets really greasy and shiny as the day progresses, so I wanted something to mitigate that problem. This claims to matify, as well as add volume and texture, which is exactly what I wanted. Also, I was so pleased with Hanz de Fuko's Sponge Wax, so I decided to give this a try.
It works great, but the only problem is I can't get it to stop working. It's nearly impossible to wash this stuff out. I tried many different shampoos, including the Hanz de Fuko shampoo, but nothing works. Even after a few days of having NOT used the Quicksand, I can still feel the dry, "pumicey" texture in my hair. Conditioning after shampooing helps to bring some relief to the overwhelming amount of texture that this product creates, but not enough. After a couple weeks of continued use, my scalp started itching like crazy and the dandruff started. I guess that's why they call it Quicksand...because it sucks every bit of moisture out of your hair and scalp!
Depending on your hair type, YMMV, but I've had nothing but mostly annoying or even damaging effects to my hair and scalp from using this. I will be going back to the Sponge Wax which I think provides the same amount of hold and matte finish, only with less dryness.
