I don't know if American crew has helped me in any way but it sure feels good applying it to my scalp. It's green but it hasn't coloured my scalped, it dries quickly, it smells good, it's long lasting I bought two bottles a year ago and I'm just nearing the end of the second at the moment.
One thing I must say, if you use nizoral a couple of times a week your scalp is quite dry afterwards, but applying american crew folligen seems to get rid of the dryness and your scalp feels quite cool afterwards.
