Eyebrow dye!!

I struggle with having blonde eyebrows when I’m brunette, I’ve been using henna dye but it is semi permanent and only lasts 2 weeks maximum, I don’t want the hassle of dying them constantly and hair falling out.

A friend recommended beard dye so please let me know if this works and what brands etc? I do not have lots of money so something that’s on the less pricey side would be the best! I don’t mind if it’s a good tint either as long as it’s long lasting. Any help/suggestions is appreciated 🫶
