In our new collaboration with Babe Lash we are able to offer their brand new serum designed specifically for Brow Growth! 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 4-month supply.
