If you don’t mind heat styling, Haley recommends starting with heat protection spray, followed by a curling iron or straightening iron (check out the video for her technique!). For a simple heat-free way to style curtain bangs, spray a little leave-in conditioner onto damp or second-day hair, twist and pin the bangs back. Let them air-dry for 30 minutes while you tackle other to-dos on your list.
