Vegan friendly products are my go to so I was happy to stumble across this brow tint from Hally. It's really easy to use, and it doesn't take long. The packaging says to do 10 minutes but for a darker effect do 15-20. I did 10 the first time and was happy with the result, but I'll probably try for 20 next time and see how it goes. I like that I don't have to fill my brows in when doing my makeup routine to make them look fuller, this substitutes having to do that. It stays on 3 or 4 days which is awesome.I also like that it has the spooly and the little cover for your finger to help wipe the tint off when you're done. The only thing I noticed that was kind of annoying is that the cover sheds easy and there were little black fuzzies. It was still effective though at wiping off and the fuzzies were easily wiped off.For reference, I have darker brown hair and my eye brows are a little lighter. I used this in the shade expresso.
