If I'm applying RU twice a day, do I need to wash my scalp before each use? Or, for example, can I wash my hair and apply it before bed, then wake up in the morning and re-apply it without washing? I don't want to waste any. Thanks!
I ran out of RU a few weeks ago. I'm not sure if it really did anything or not. If I start losing ground I'll probably hop back on. But yeah I was also washing twice a day just to make sure I wasn't wasting any product.
