I've definitely had my fair share of brow waxing accidents. I would suggest taking a Phytophanere Dietary Supplement - Hair & Nails. These vitamins are specifically designed to promote hair growth (including brow hair). I would recommend taking two caplets daily (during the mornings and evenings) for 2-3 months or until you see your brow hair replenish. In the meantime, I'd recommend a brow filling powder. Too Faced's Brow Envy Brow Shaping & Defining Kit includes everything you'll need to define your brows including two different brow powders which can be used in conjunction to create your preferred brow color. This kit also includes brow stencils for perfectly defined arches.
