The sensation you feel when washing your hair with the shampoo is like it goes to the scalp and penetrates to your hair roots. The conditioner I just wanted to spa my hair in, The tingle of menthol is superb and I don't usually use scalp treatments because of my sensitive scalp,but this one is very gentle even combined with hairfood. I do weaves a lot and my hair is thin, but for the week I had no weave my hair is really fuller. I haven't used this product long enough to say there is a big difference, but there is a definite change in my hair texture. I'll be able to tell in another month.
