Question: if you exercise everyday how often should you wash your hair?
Answer: You don't have to shampoo every day. According to Redway, if you're doing heavy cardio daily, you should wash your hair two to three times a week. “Rinsing your scalp in between shampoos will help clean it. And if you have curly or textured hair, co-wash [with conditioner but not shampoo] in between.
