My favorite brow product is from NYX Cosmetics South Africa.
When I first started doing my makeup this was the first product I used, and I still use it. It comes in many shades, includes a brow wax to keep those brows in place. Great for bushy brows that you want to control or a very defined brow. As well as having a brow brush and applicator to get that precise definition.
All in one convenient little case. A definite 10/10 for me.
