how to cover hairline area?

I recently lost pretty much all my hair, and I have decided to wear a wig at school. It’s only a temporary solution as my hair is growing back so I plan to stop wearing the wig in a few months when (hopefully) my hair grows long enough. However, the wig I have is one of those ones with obnoxiously thick bangs so they cover the hairline area of the wig. The wig also doesn’t have full monofilament throughout, only in a small point further back. The hair is kinda thin towards the front and the cap is somewhat visible so I’m hoping to cover that area (from the front to around 3ish inches back) and tuck away the bangs somehow. My school has a uniform so I can’t wear things such as caps or beanies, but I’m pretty sure headbands and bandanas and the like are allowed. Right now, I’m planning to just wear those thick fabric headbands but I’m hoping to find an option that’s more subtle as I never wore accessories before I lost my hair and I personally don’t like it when my forehead is super exposed as it would be wearing a headband. Any help would be much appreciated!
