Lash extensions enhance natural eyelashes with individual lash fibers applied using a specialized adhesive. They are available in various lengths, thicknesses, and curls to achieve desired looks. These extensions typically last several weeks as natural lashes shed. Regular touch-up appointments are recommended for maintenance. Proper care, including avoiding rubbing or pulling and using oil-free makeup removers, helps prevent damage. Lash extensions are a popular, mascara-free option for longer, fuller, and more glamorous lashes.
