I received this in a Mystery Sample Pack.
First of all, let's talk about the smell. It is a very strong minty/citrus smell and it sticks to your hair way too well. I washed my hair with this, then a day later washed it again with another shampoo (twice!) and the mint smell was still present. So if you want your hair to smell like mint, this would be an amazing product for you.
Secondly, the whole "no-foam" idea is interesting in theory, but in practice I couldn't tell which areas of my hair had gotten the product on it since the foam is usually how I can tell. I have extremely thick and long hair that needs a thorough shampooing every few days. This product just weighed it down. It was so greasy feeling immediately after I tried to washed it out than I tried a few more times just to attempt to get rid of the greasy feeling. Didn't work.
On the whole, I couldn't stand this shampoo, and won't even use the rest of the sample up. Once was way more than enough.
