I tried this while watching Kiwoo teacher's YouTube. Even though it was my first time, it was easy to do and I didn’t have to adjust the amount, which was convenient. My skin is a bit sensitive so it stung a little, but after applying calming cream it got better quickly! I have thick and dense eyebrows, and leaving it on for about 13 to 15 minutes dyed them a natural brown! I don’t think this would suit those looking for a lighter brown. Since it’s a dye, it has a bit of a smell. I haven’t tried other products so I can’t really compare pros and cons, but I was satisfied 😊
