In many cases women (and men) suffer from brittle, soft and chipping nail plates. And the natural nails can be extremely stressed and weakened. In addition, grooves and uneven nail surfaces don’t offer themselves as a perfect polishing surface. Natural Nail Boost Gel with Keratin contains Keratin which provides protection and nourishment to natural nails as well as more strength and resilience. It functions as a protective shield and prepares the nail surface optimally for the application of nail polish.
