Honestly, since they are bangs... I mean you should be careful about heat damage, but you will be constantly cutting them to keep them short so you'll probably end up cutting off the heat damage anyway. I don't know, it's up to you. The worst that will happen is you'll have heat damage that will leave your hair kind of straightish/give you split ends, etc... and you'll have to cut the damage off, which will be fairly simple with bangs since you can grow them out easily. It's your call.
Mostly 3c and lovin' my curls

This is not a fashion trend, it's not a statement, it's pride for who we are and what we look like. And that is where our true beauty shines.
