I need wide headbands that actually stay in place.

I have hair loss at the crown of my head and need assistance covering it up.

I got these ones (from Temu), and they do not pinch behind my ears (a first for me) which is amazing in itself. On top of that, they are cute, especially IMO the red one!

All I do lately is shop there. My goodness, I should stop already, so a lot of my recs lately are from there (sorry if not allowed, please let me know!). I have the navy one and the red one, because to me those were the prettiest in my hair (I have dark hair).

I have a somewhat high forehead and a sparse hairline naturally (fine hair) and on days that I'm feeling self-conscious about it, I wear tube (Buff) scarves to cover it. They can be folded into as narrow or as wide headband shape as you want, they come in myriad colors and patterns and they can be as cheap as 1€ if you are not buying the original Buff (those start around 16 € and more, at least where I live).

Last week I wore a dutch braid, started braiding from the hairline (forehead), fluffed it up, then put on a pretty tube scarf rolled into a head band and it was a great look, if I say so myself.

The best headbands that really stay put are velvet wig grips. They aren’t wide necessarily but you can put anything on top of them: scarves you already have, etc.

What if you got really long bandanas/headscarves (if you live in a place with access to Indian or African fashion, you should be able to find them pretty easily) and fold them to your desired width and then tie them back? I think that would be really cute and conceal your hairloss at the same time.
