Let’s first talk about how to fill in your eyebrows. I start with a brow brush and I hold it against the side of my nose vertically. On the brow bone where the brush hits, is where your brow should start. Next you are going to take the same brush against the side of your nose again, but going over the middle of your eye. This is where the the peak of the arch should be. Lastly you are going to take the brush against the outer end of your eye. That’s where the “tail” of the brow should end.
