back combing works, but it's just one way to start sectioning hair. The problem with back combing verse tnr is that with combing you then have to palm roll them to get them to be flatter, cause they are just giant puff balls at the end. You will probably have t keep rolling them as they puff up again. Why waist time with that.
With tnr, they are sectioned, and you can just leave them be. They don't really puff out that much and all you have to do is separate them when you shower. Easy as that.
Plus with back combing you end up pulling out tons of hairs. Tnr leaves them be. It just tangles them up.
I'd leave your alone. People feel strongly about the way they grew their locks. When your are a year old and look great, you can look back and say you made the right choice. And when they look good in a month or 2, your friend wont be able to argue with you.
As for wrapping them up at night. Bad idea. What helps them lock is how they get to rub around and move freely at night. Some people put them up in a tam, but everyone agrees that it just falls off sometime at night. So why even bother.
