Nanolash Step 1 Lift is the first of the three key formulas that guarantee satisfactory results. Used as the first step, it works by opening the hair cuticles and creates lash-lifting effects. Eyelashes become more manageable, and are prepped for next steps. The activator for lash lift and lamination is made out of carefully-selected substances for lash-conditioning properties and smoother, shinier lash appearance. Lashes also become more flexible and resilient.
