i used to have a problem with dry shampoo. i still had too much oil in my hair and my scalp was coated with powder. they make a wet shampoo that you don't need to wash out for in hospital and post hospital stays. it works really well. you just rub it in and brush or comb your hair. there are several on the market i know these work. i have had feedback at work. i work at a pharmacy, i have never used this myself though, so this is just from the feedback but all was positive.
