I wear two flat-twists as my protective style - they look like french twists.
I DC on Saturday/Sunday, moisturize, seal, then twist it up. I get my hair wet and 'moisturize' every day - I like to rub a bit of a leave in on the exposed parts, and mist with my mister (water, conditioner, homemade hair oil). I take it down, and condition it again on Wednesday, moisturize, seal, and twist it back up. Wash, rinse, repeat, for weeks on end.
