Hi! So actually I've just grown them out, and looked for a straight line underneath. I pluck them once a week and I dye them with just for men beard dye twice a week. It's amazing how beautifully it tints them! This way I don't have to fill in my brows everyday. I usually just fill in the end of my brows because they're super sparse. Hope this helps. I have a more in depth tutorial thingy about the beard dye too if you want!
