I'm huge on both Shampoo and Conditioner, but I've found that to really have my hair healthy and not super flat and super glossy looking, that I usually shower w/o shampoo and conditioner about 6/7 days a week.
At the cost of looking a little bit frizzy, and letting my hair dry naturally, it makes it nice and wavy and give that "Jesus look" which I'm kind of liking now.
