i would obviously shower in the morning and maybe wash your head or condition that way it will smell good.bc at night your hair gets all these chemicals from the pillow and stuff and then it will be very dirty so i suggest you wash your hair in the morning and at night if you want to.How to keep hair from smelling like oil in the morning?
