One of the keys for me is going to bed right
after applying products. Then it's more like plopping. One person PMed me about this and said that wrapping her hair in a microfiber towel worked better so the friction of rolling during sleep wouldn't muss it up.
My hair is too thick to be dry in the am if I wrapped it.
Yes, my hair isn't crunchy in the morning, but it has definition and actually much more curl than if I let it dry while vertical.
Oh, there was one product I couldn't sleep on... Curlisto Structura Lotion
... had to air dry completely bone dry and then could sleep on it.
