PROPERTIES Nail biting is an uncontrollable habit for many children and adults. To help them quit, Mavala laboratories have created Mavala Stop, a harmless, transparent product with a characteristic bitter taste. It can be applied alone or over nail polish. It helps stop putting their fingers in their mouths and biting their nails. It also prevents young children from sucking their fingers. HOW TO USE At night, before going to bed, apply a layer over the entire surface of the nail and let it dry for a minute. Repeat every two days until the nail biting habit has disappeared. After ten days, their nails will grow normally. They may need strengthening. In that case, we suggest Mavala Scientific and Cuticle Cream to complete the beauty of their new nails. Not recommended for children under 3 years old.
