Mavala Scientifique is a specialized nail hardener treatment that strengthens weak, brittle nails. This penetrating solution works by improving the cohesion between nail layers to prevent breaking and splitting, making it an effective solution for fragile nails. The product comes in a 5ml/.16 fl. oz bottle with a precision applicator. For best results, it should be applied to clean, polish-free nails, focusing on the nail tips where breakage commonly occurs. The formula is designed to penetrate the nail plate and should be allowed to dry completely before applying other nail products. This is a professional nail care treatment from Mavala Switzerland, known for their expertise in nail care solutions.
