How often do you shampoo?

I just want a fun discussion and see some of youre routines and schedules and how different things work for us. Like not just how often, but with what? Do you have a favorite shampoo off the shelf or are some of you one natural home remedy goddesses I wish I could be lol do you brush your hair in the shower like some ladies I know? Special oils? Do you look forward to wash day or do you dread it?
