In our collaboration with Babe Lash we are able to offer their Amplifying Brow Serum! Get brows that look thicker and bolder with this castor oil, vitamin, and antioxidant-infused serum. It's ideal for brows that are thin, over-plucked, or just need a little extra love. Plus, it protects against fall-out caused by environmental stressors. This bottle of serum is a 3-month supply.
