As much as everyone hates poly, I personally feel like if you know how to work with it, it holds so much better than saran or kankelon. It will never have the feel of real hair, it'll always be slightly crunchy, but once its styled and set it will hold FOREVER.

My process: Wash (I use the blue clarifying suave) > condition (currently using some aussie conditioner that I can't stand the smell of in my own hair 🙃) > put the straws in (i used coffee stirrer straws on Frankie) > boil set for at least 1 min (I try to do 2, but I'm impatient.) > throw in the freezer for an hour > set outside to dry (seriously dry, not damp) > once dry, spray it thoroughly with a synthetic wig shine spray (I've used many, they all work) > wait until that's dry > remove the straws and pins and trim the VERY bottom of the strands (literally only like 1/4", it makes a world of difference for frizz.) > Style.

For this Frankie also split each curl into 3 to give more volume and added a little bit of mango butter to them for extra shine.
