Lash FX signature grade adhesive now features an improved formula. It offers high strength and is partly flexible with excellent resistance to humidity. This improved formula has a slightly faster setting than previous adhesives and has a very low odour. Formulated for maximum client comfort and long lasting eyelash extensions. It is recommended a patch test is carried out behind the ear before use. To further reduce any odour Lash FX advise to use an air blower.
