Apply your leave in.
Part hair down center, from hairline to crown.
Start to comb or brush around head, just like you would with a dry wrap.
Continue combing until all hair is wrapped around head completely.
Tie down with silk scarf.
I don't know how long you will need to leave your hair like that to dry. I can't do that method myself, as my hair is too thick, but my girlfriend used to use that method and she'd be dry by morning.
