This shampoo is quite effective at cleaning and maintaining the hair. It is also cheaper than the leading name-brand equivalent alternatives on the market today. If one is looking for a color protecting shampoo, then I would recommend this product for its combination of effectiveness and low cost. Effectiveness In my experience, this shampoo does work well. It works quite well at removing dirt and grease from the hair, and it leaves the hair feeling fresh and clean. This shampoo is also effective at maintaining color in the hair, at least from as much as I have used it. Those types of results certainly can vary from person to person, so it may not be for everyone. But for me personally, it has worked well. Scent This shampoo is unscented, which I actually prefer over the scented kinds. This one gives a clean and fresh scent that is very pleasant without being overpowering in any way.
