The primary reason to shampoo hair is to remove the excess oils, dirt and accumulated dry, dead skin cells exfoliating from the scalp. It's important and necessary to go beyond this simple reason, and Nick Chavez Beverly Hills Shampoos can take you there. One of the problems with shampooing is that, if the formula is too harsh, the natural, essential oils on the hair shafts and the scalp can be stripped away, drying out the skin and the hair strands. This not only causes the scalp to begin to flake (causing dandruff), but making the hair dry, brittle and lifeless. As a result, the hair can easily break, form split ends and become difficult to style.
