OP, I couldn't agree with you more. When I was relaxed, my hair THRIVED from rollersets. That was the only way I could dry my hair and get it silky. Airdrying and blowdrying caused breakage.
I'm type 4 natural now and I'm trying to get to MBL by the end of the year, so I'm getting ready to start rollersetting again. It won't be easy, but I'm committed.
