Hi , im going gym daily, I spend 2 hrs in gym in evening hrs, after gym I taking cold water bath & daily im using shampoo for my hair, from last week onwards im observing my hair color is slightly changed & feeling itchy on scalp, is it because of daily wash of my hair or any thing else, I apply weekly twice conditioners & oil on different days. Is it normal to use shampoo daily after gym or not. Please suggest me.
