Lash lifts enhance your natural lashes by adding curl and definition, offering a natural, easy-to-maintain look that lasts 6-8 weeks. Lash extensions, however, involve attaching individual fibers to each lash for a fuller and longer appearance, requiring upkeep every 2-4 weeks for those desiring a more dramatic effect. Choose a Lash Lift for a natural enhancement or Lash Extensions for customizable volume and length.
