A lash lift is like a perm for your lashes. It is also an alternative to eyelash falsies and eyelash extensions to give you a curled look effect. Lash lifts set the shape of your natural lashes using a chemical solution that is safe for your eyes. It is also a replacement for your lash curler so you won't have to worry about pulling out your natural lashes. This lash lift lasts up to 6 weeks depending on your aftercare.
