Washing your hair every day does strip the scalp of natural oils, no matter what your ethnicity is. Many black women have perms, weaves or extensions that can be kept clean and tidy with daily maintenance and a scarf to sleep in at night. I know many white women with long, thick curls who don’t wash their hair every day because it is too much to deal with, also. As a black woman, I know that most black women (particularly with thick, tight curls) do not wash their hair every day for the same reasons. I wash my locs once a week. Your hair shouldn’t get ‘dirty’ unless you are rolling around in dirt on a regular basis.
