Im not waist length yet..........but i will post to bump.
Right now my hair is behavin! That ORS Pak
. I rollerset on Monday and it was a bit of a challenge, when your hair extends past the length of your arm, but i managed by wrapping the ends first. It came out nicely.
Flatironing was not bad at all, but somehow i cant seem to curl with it. Im fine now, but with 3 more inches I will be able to really answer your question.
