This is what I do if I want it real flat. After I take the rollers out, I use a straightening balm(I use KMS Flat out) before wrapping it and getting back under the dryer for 10 minutes. Or I will mist it lightly, rub in some jojoba oil or whatever you want instead of the KMS. A lot of times after getting from under the dryer the 2nd time I'll just leave it wrapped and go to bed. In the morning don't unwrap your hair until you are ready to walk out the door. The shower will steam it a little under the shower cap and keeping it wrapped until you walk out the door makes it flat. Also if the weather is misty or it is raining, I'll carefully remove the scarf, don't disturb the wrap itself, and pull a hat over my hair until I get to work...then I unwrap my hair.
