I tried the Infusium 23 shampoo quite a few months ago because I had a coupon and I like to try different products. I was shocked that this shampoo was still on the expensive side even with a coupon and though I really liked how well the product worked I have only bought a bottle a couple of times since. I did love how gentle yet effective this shampoo is but not very cost effective compared to other brands. Effectiveness The Infusium 23 shampoo worked very well with my oily hair and didn't seem to dry it out as other products have. This shampoo made my hair feel soft and luxurious as well as easy to brush out. The shampoo deep cleaned my hair down to the scalp without stripping my natural oils of neither my hair nor scalp. Scent I adored the scent of Infusium 23. It was neither a heavy scent or too light of one, the fresh, clean scented shampoo clung to every strand of my hair and lasted until the next time I washed my hair.
