We HIGHLY recommend this Primer.... Used to prep the lashes before lash application, our primer is very unique. It removes oil, proteins, and makeup from the lashes to secure a strong bond/stronger hold for the adhesive therefore extending the lash retention. 
 
Best if used on clean/shampooed lashes. Apply ONE drop each on two flocked applicators, then go through the base of the lashes and clean thoroughly. 
 
Again, to get great retention we highly recommend cleansing the lashes first (at least within the hour of appointment and no rinsing with saline!), then using the primer. 
 
Great retention comes from clean lashes!
