Some hair tends to get greasy more quickly than others. People with oily hair often have the reflex to regularly shampoo their hair to degrease it. However, this can have the opposite effect! Indeed, hair damaged by over-frequent shampooing will dry out and the scalp will produce more sebum. You are then in a vicious circle with hair that gets greasy too quickly! We recommend spacing out your shampoos and using our DIY recipe for oily hair. It will help slow down sebum production between washes.
