I have black Asian hair, and I must say I don't really have jet black hair but I still bought the black shade because I really love dark brows that have ashy tones. The black shade isn't completely black though, it still has some taupeness to it which is great because I don't really want to look like I use sharpie on my brows. Anyway to my real review: I tried this so many times just to make it work for me, but it just wouldn't on its own. The consistency is very dry and thick, so when you apply it on the brows you don't really have enough time to blend it, as it sets so freaking fast. I don't know if the product I got is just way too thick or it's just drying out or if this is really its consistency. If you can blend this well then I applaud you because I really can't. But hey, since I'm one of those people who hates wasting product and wants to make everything work, this is what I did: I took my old eyeliner gel (in a jar), cleaned it and put a few amount of the nyx eyebrow gel, and then I pour a little bit of argan oil and I mixed the two together. I don't know if this will work on other oils but since argan oil is what I have, I used that and it worked great. The consistency becomes very runny and oily, but good god it was so much better than its original state. I was able to apply this product on my eyebrows easier, smoother and much more natural but still thick and full. This hack is so much better because it's faster since it's already in the jar. If you're having the same problem as me then give this hack a try. PS the formula also didn't change at all, it just made it runnier and not thick, but it's still waterproof and smudgeproof once your eyebrows set, this will really just give you more time to blend your eyebrows. I will probably still buy this again once I run out because it's water/smudgeproof, but if not for argan oil I wouldn't anymore.
