How open should I use shampoo?
There's no harm in washing your hair every day, unless you start to see a lot of breakage. The entire wetting, drying, and styling process takes moisture out of your hair. Wash every day if you have oily hair, live in a polluted city or humid environment, or work out daily. Wash every other day if your hair is normal or combination. Wash every few days if your hair is on the dry side (this includes curly or color-treated hair, as well as the hair of most African Americans) or if you live in a rural environment or dry climate (hair stays cleaner longer when there's less pollution and humidity)
