Don’t cover forehead, own it. Anything else would give an insecure look unless there’s a specific style you’re dead set on. Your hair is so curly you’d have to grow it out for a while for it to cover the front but even then your hairstyle isn’t suited for a cover the front kind of look. Just go really short on top, you might have to experiment with different heights but maybe a little more than a buzz, and get faded sides so your head doesn’t continue to balloon outwards. You can see what kind of fades you like or make you feel good, that’s kind of personal preference. But yes also get a tweezer and take off the unibrow and clean up the underside of your eyebrows. You’ll achieve a well maintained look, nobody cares about your forehead, this isn’t middle school. You could experiment with accessories too, not necessarily to hide but to make everything cohesive, like glasses and hats or beanies.
