Hey there? are you talking about wrapping 4B hair that has not been pressed or flat-ironed?! Let me know how that works out.
My hair is 3c-4a. Now that you brought this up I will try to do it like relaxed heads do: after washing and DCing, apply leave-in and setting lotion or what ever and wrap using my denman to keep things in order. BUT since I am pretty sure that my hair will try to spring back, I am going to quickly tie a silk scarf around the hair and then sit under the dryer. THink that'll work?
When I want to wear my hair straight I usually just flat iron and wrap it to maintain during that week. I too would like to hear from some responses from ladies who wet-wrap kinky-curly hair.
