Annoying hair flips?

I naturally have thick, somewhat wavy/frizzy hair and I usually straighten it. For some reason, it likes to flip out / curl out at the ends like this, even after using a flat iron. (Not my picture.) It's stubborn and blunt-looking like in the picture.Any thoughts on types of haircuts, techniques, or products to avoid this? via /r/FancyFollicles https://ift.tt/2lCyCt0
