This by far is one of the best shampoo and conditioner duos I have ever used. I am a woman color and at times experience unruly hair. I often battle the frizzies, really dry, or dull looking mane. I have spent quite a lot of money on ethnic products- that work really well, but were not so convenient to obtain. I would either have to order online and wait for the items to ship or drive around to find them. The keratin ingredient in these products caught my eye, so I figured I'd try these out. These products tame my hair, leave it silky and smooth, make it manageable and easy to comb through, adds bounce, adds shine and leaves my hair smelling great. NO KIDDING. And the deliciously, chocolaty icing on the cake, is that I can find these at almost any drugstore.... so no more waiting on the fed ex-guy.
