do you massage through your scalp when rinsing (going from the hair line to the back of the head)? and is the water warm enough to cut through the grease? i mean .. if you’re doing this everyday AND shampooing twice a week, it shouldn’t really be a problem. Do you come back home and then shower, or do you shower in the gym? If you’re coming home, then you can ofcourse use shikaki .. in the gym … you could just use baby shampoo .. but you have to be quick with the shampooing so that you arent OVER-cleaning it.
