Just like a normal nail polish, you have to wait for this product to dry. It does dry relatively quickly though. If you are looking for a product that will provide you some added strength to weak nails that break often, this product can help. The most effective way to use it, is to start by applying two coats (letting the coats dry in between) and follow up 2-3 days later with another coat. Repeat the process as long as needed, completely removing the product at least once a week. If you have very dry, brittle nails, I would suggest a different formula of Nail Envy that is geared more toward that specific problem, or use this product in conjunction with cuticle oil daily.
