How do nail strengtheners work?

Similar to a hair masks, nail strengtheners contain proteins and vitamins and that help fortify your nails. They also add a layer of physical protection, so your nails won't dry out or break while they're healing. With that said, Hora notes that their formulas can only do so much: "Nail strengtheners will do the outside work, but essentially the diet will do the inner work of keeping nails thriving."

What ingredients should you look for in a nail strengthener?

Nail care isn't too different from skincare. Choi recommends a slew of ingredients that are often used in skin care products, like vitamin E, biotin, keratin, which all work to nourish and improve nail strength. Similarly to how vitamin C can brighten your complexion, it also adds a sheen and a level of protection to nails. If your nails are looking dull, opt for products with AHAs like glycolic and lactic acid to restore and rejuvenate the nail surface.

Will nail strengtheners help damage from gel manicures?

Your fingers literally can't get to Amazon quickly enough. Yes, if you're experiencing dry, thin, brittle or peeling nails from a too-long stint of gels or acrylics, give yourself a breather and stick to a strengthener. "I recommend applying nail strengtheners every other day for best results," Hora advises. With regular use over a few weeks, strengtheners will have your nails right back in the game.
