THINKING ABOUT THE "AFTER" TREATMENT - Keep the lashes and brows dry for 24 / 48h - Avoid oil & mascara for 24 / 48h - Do not rub the lashes and brows -After 24 / 48h, it is good to rinse them with cold water - Brush brows and daily & moisturize the lashes daily with our setting solution that is available for purchase at the studio. This is super important & keeping the lashes and brows moisturized makes the lashes and brows look freshly made, stay moisturized, and minimize frizz when they grow out. As with all treatments, you can of course be allergic, but it is not so common, contact us before if you want to do a free allergy test. If this is not taken care of, it can lead to the lash and brows permanently dropping and the lashes regaining their original shape.
