Kiehl's Amino Acid shampoo smells great because one of the main ingredients is coconut oil. If you're a bloke, don't let this put you off because the smell does not linger once you have washed the suds out. It is a mild shampoo and I use wax in my hair but have no problems with washing it out every morning and find that it lathers up really well. The good thing about this product is that, as with all Kiehl's products, it is made from all natural ingredients so does not contain strong detergents like some other cheaper products. Once again with all Kiehl's products, the Amino Acid shampoo is not cheap but I do find that a little goes a long way so don't have a problem with recommending to this to all.
