daniPro Nail Recovery Treatment is a new development in nail treatment that incorporates coconut, passiflora, apricot, avocado, and salicornia oils. The deep treatment is formulated to target dry, brittle nails to make them feel stronger and silkier. As with all daniPro products, Nail Recovery Treatment is infused with undecylenic acid to keep nails looking healthy, and it is toxin-free, steering clear of the top 10 toxins found in many nail treatments and polishes. The Nail Recovery Treatment can be used as a base coat for nail polish and should be applied twice a week for 3 weeks for optimal results. All daniPro nail polishes are vegan, cruelty free, and made in the US.
