Our Prep & Prime is unique as it will remove oil, proteins, and makeup from the lashes to secure a strong bond while adding nutrients to the natural lashes. Use to prep the lashes before lash application providing a stronger hold for the adhesive extending the lash retention. Use one drop of Prep & Prime on one prep brush per client pushing a second prep brush into the wet one, then gently pulling outwards from the root to the end of the natural lash.
