Amway is an international brand where we dont get in market easily.coming to the stinique shampoo from Amway it is quite different.Its 100 ml cost is more and even the quantity is very less.when we compare with other shampoos , we dont feel satisfied as we dont find any difference after using it.Many of them dont know about this Amway shampoo. I think these amway products should be sold even in open markets so that people will know about it.thank you
