Sally Hansen Miracle Nail Thickener strengthens soft, thin, and ridged nails with its Calcium and Ceramic Gel formula. It creates a protective shield that fills in ridges and imperfections, making nails thicker, harder, and stronger. Apply one coat to bare nails; for thinner nails, apply daily for up to four days. Use alone or as a base coat for added resilience. A must-have for any emergency manicure kit, it embodies Sally Hansen's commitment to salon-tested solutions and fashionable colors, empowering you to create salon-quality results at home.
