I am a cancer patient. When I was undergoing chemotherapy, I lost all of my lashes and all of my brows. As soon as I got past chemo, I started using the Brow Bond and the Lash Bond. Here are my brows 9 weeks post-chemo. My lashes are now back, longer and thicker than when I started chemo! I love this product, as it has helped me look and feel great!
