Simply brush this lightweight, non-irritating formula on your lashes and brows twice a day for visibly healthier, less brittle looking lashes and brows. Nu Colour Lash + Brow Serum does not cause hair growth. Rather, the visible benefits to your lashes and brows result from improved nourishment and conditioning of the hair. After cleansing and drying the application area, apply a thin layer of the serum to the root of your eyebrows and along the root of your upper and lower lash line. Use daily, both morning and evening.
