Answer:
I really don't think there's a fast, quick way to straighten your hair especially since its thick but what I usually do since mine is also straight, is I-
Do layers......take some hair, and put it up in a clip or something that would hold it up and straighten the other hair left down and keep on doing that with letting other hair down. Then when you finished all your layers, go over it all.
I hope that helped. Any other help, email me at kateluzecky@yahoo.com
