This ultra-strong, vegan nail hardener is literally an absolute power product. It forms a protective shield, seals the nail surface, strengthens the nails and makes them more resistant. 90% of the testers confirm that their nails are harder and stronger after application. They also state that their nails break off less as well as looking better and healthier. Apply the polish twice a week to achieve this. The transparent formula can also be worn as a base coat underneath colour nail polish.
