You can use an iron that straightens the hair. Slide it thru your hair to the bottom then curl it up for 30-60 seconds. I have never did it but i have seen someone do it and came out really nice. Good Luck!!
I have a friend who is in seminary now in E”Y who is very good at doing make up, hair and stuff like that and she doesn’t charge a lot. She used me as her model for her website, she used a more professional like hair curler, where there isn’t that clipping part of the curler.
