With Gel-X Prep, you can ensure maximum adhesion and strength without the trouble of etching the inside of the tip. No more dust, no more extra time! With a good scrub of our non-acid Gel-X Prep, the inside of the Gel-X tip will be properly chemically etched and ready for Extend Gel application. Gel-X Prep also works to prep the surface of the Gel-X tip after tip application, buffing and texturizing the surface to create the perfect base for color application. We’re not kidding around when we named this one Gel-X Prep! With one product, get ready to be able to perfectly prep the tip for Extend Gel AND perfectly prep the tip for color.
