Hard to say... [SEP] So this is one review I have had to put a lot of thought into. Being that this is not something I'm familiar with using I wanted to give it a fair chance for me to learn how to use it first. To start off, unless you're already good at this type of application, it will take a few tries. Maybe watch some youtube videos, which I did. Secondly, once i did start to get it, I realized that this product isn't necessarily compatible with me. I'm Asian and blessed with the lovely genes of having very little eyebrow hair. I have an okay amount toward the center of my face and as it moves away, it decreases to where I rely on a few single hairs lining up. This does a GREAT job filling in where I do have hair. But it quickly turns to where it doesn't look nice if I try to draw in the hairs where I have nearly none. In the end, I can appreciate this product for what it's capable of, but it isn't for me. It doesn't last days, just until the next time I wash my face. But it might have something to do with my face being a little oily and using oil based cleansing soap.
