This product is by far the best shampoo I have ever used. It cleaned my hair better than any other product I can find while only using half of the shampoo. It's worth every penny, and I might even buy some more when I'm done with this bottle. Effectiveness I used to have to massage my scalp for five minutes when shampooing my hair, but I've noticed that it only takes about a minute to get my hair and my scalp clean. Saving time in the shower is a plus when your a busy person. Scent The scent is pleasant and lasts throughout the entire day. I have become so used to the smell of my other shampoo that I didn't realize all the other great smelling shampoos there are. Kronos has made it perfect, it's not overpowering, but if you love great smelling hair that lasts all day long, then this is the product for you.
