As you know, with ethnic hair, in order for it to not get knotted up, it has to be washed in a downward motion by raking the hair with the hands. The tighter the coils, the more careful you need to be. White people generally don't have to do that. They can just vigorously scrub the cap out of their hair. That's what I'm referring to.
