This shit works WONDERS. Never used to use base coats but now that I started using this stuff I will never stop! My nails grow so fast and are hard as, well, rock plus my nail polish chips a thousand times slower. <3
If you are tired of nails thin, fragile, or if you bite your nails and want to change their appearance, you need gelatin. Gelatin is a cure cheap, easy to find in many stores, and the effects of such treatment done at home will delight you.
