Looking for a do-it-all product that can be used as a top coat, base coat or on its own? The search ends here. Duri Rejuvacote’s versatile formula features two types of protein, keratin and calcium, which work in tandem to stimulate growth and seal in moisture.

2. Opi Nail Envy Nail Strengthener Treatment

Best After Gel Removal

This formula uses pure science to treat your nails; Hydrolyzed wheat protein and calcium chemically react with the protein in your nails to make them harder. Neat, right? We love this formula for its focus on sensitivity and peeling, an unfortunate side effect that sometimes occurs when you remove gels, acrylics or dip manicures. Bonus: It can be used as a standalone treatment or a base coat alternative.

4. Reserveage Nutrition Tres Beauty 3, Beauty Supplement For Hair, Skin And Nails

Best Supplement

If you can barely remember to wash your face and don’t want to add another step to your beauty routine, consider trying a supplement in your morning multivitamin lineup. This daily pill targets nail growth and strength from the inside out with collagen, keratin and elastin, but it also benefits hair and skin, too. One PureWow editor took these to grow out her bob while in quarantine, but noticed that her usually brittle nails also grew rapidly and became super strong.

But it’s also made with a host of other antioxidant-rich botanicals (like grape extract and sunflower seed oil) and keratin to deliver five key benefits: nourishing, hardening, hydrating, growth stimulating and breakage prevention. And don’t let the minty green hue fool you—it goes on totally clear, so it can be worn alone or as a base coat as intended.

Instead, apply this fortifying base coat before nail polish to add moisture back to dry, cracking nails to keep them from breaking.
