Help me find the right at home brow tint please!

I would like to start tinting my brows for various reasons, but it’s not a service offered often in my neck of the woods. So, I plan on doing so at home (I’m no stranger to diy beauty services).

The issue I’m having is finding a good quality, henna free, long lasting brow tint in a very cool tone medium-dark brown. I have a neutral olive undertone, so anything with henna turns bright orange after a day & looks horrendous. I also have oily skin, so something that doesn’t fall apart easily would be preferred.

Which brands/products would you recommend? I don’t really care what the price is as long as it has good longevity, doesn’t have henna in it, & comes in a color I can work with.

Thanks for the help!!
