I voted every day, although ist's "only" 5-6 times a week. I'm lazy too but I found a simple routine that works OK for me.

My hair takes ab. 2 hours to dry, I'm kind of famous for leaving the house with wet hair.

2nd day hair means knots and tangles. Trying to get those out means cotton candy.
3 a/b wash with any cone-free conditioner, light gel or condish for styling

I'd rather have my hair a little bit frizzy than producty
