Whenever I style my hair, it just falls completely flat after an hour. I have 2b-2c loose curly to wavy hair, and I can usually style it anywhere from full curls down to a looser 2a wave. But I can never get that classic curtain wave to swoop out at the sides—it feels like my hair naturally grows backward. I’ve tried adapting to its natural pattern for a bunch of styles, but I'm bored with it. I want a totally new look. What should I do? (In case I couldn't explain it properly, here's a style I'm talking about)
(I have much longer hair than in this picture, but it's just a reference)
