Achieving the best retention in lash applications requires both technique and product knowledge. One key factor is avoiding applying lash extensions directly on top of the natural lash, as this method has been shown to reduce retention effectiveness. Instead, properly positioning the extension on the natural lash without overlapping ensures better adhesion and longevity. The choice of lash glue is equally important. Using a glue with appropriate drying time that matches your skill level helps in securing lashes effectively. If the glue dries too quickly, it may be challenging to place lashes correctly, but if it dries too slowly, the extensions may not bond well. Proper lash isolation during application is also critical to prevent lashes from sticking together, which can cause early lash fallout. Holding the lash in place briefly after application helps the glue set more securely. For lash technicians aiming to provide clients with the longest-lasting extensions, mastering these application techniques and selecting the right products can drastically improve retention. Incorporating these best practices leads to healthier natural lashes and happier clients, ultimately boosting the reputation and success of your lash business.
