How often should I shampoo

Theres no harm in washing your hair every day, unless you start to see a lot of breakage, says Jeffrey J. Miller, M.D., assistant professor of dermatology at Pennsylvania State University College of Medicine. The evidence: lots of flyaways and little baby hairs at the crown. The entire wetting, drying, and styling process takes moisture out of your hair, so heres a rule of thumb: 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 (with dry ends and oily roots). Wash every few days if your hair is on the dry side (this includes curly or color treated hair) or if you live in a rural environment or dry climate.
