Shampooing your hair every day will cause excessive drying—even if you use the very best, salon recommended shampoos. The chemicals in shampoo strip the natural oils from your hair, and the effects can be worse if you have hard water. Start washing your hair just twice per week and using dry shampoo in between until your natural hair and scalp oils balance.
You should also use only warm water on your hair—never hot. Coldwater is even better if your hair is colored or bleached. When you are washing your hair, you should focus on the roots and not saturate your entire hair in the shampoo.
