If you have your own eyebrow hairs and you're not tinting them, what are you waiting for? When I say your own eyebrows, I mean they aren't micro bladed.
Nothing wrong with that either, just no point in tinting your skin.
Eyebrows are the first part of your face that people see and the most influential part of your expression. They help accentuate your eyes and shape your face. With that said, don't go crazy tinting them either. If you have blonde hair, don't do black eyebrows. There are different shades of tint you can choose from.
