The 12 Best Clean Nail Strengtheners Of 2022 For Brittle, Flimsy Nails
Nail strengtheners have come a long way: In fact, clean- and natural-leaning experts used to advise against them in general—Nadine Abramcyk, co-founder of clean salon tenoverten, once told us—since traditional nail strengtheners and hardeners typically contain formaldehyde. Fast-forward, and you can find tons of natural-leaning nail-strengtheners commanding the market (also advertised as nail serums, treatments, or base coats) that boast plant-based ingredients, like vitamin E, olive oil, garlic, and tea tree, to effectively bulk up the nails.
Before filling you in on our list of favorites, we should note that strengthening your nails is not, by any means, a quick fix. Ultimately, it takes more than a single swipe of base coat—it may require both standard nail care practices (like hydrating the cuticles, monthly maintenance, UV protection) and internal strategies (like collagen and biotin supplements) to help the nails truly bounce back.
In other words, the best "nail strengthener" is actually a holistic, inside-out approach to feed the nails with healthy ingredients. But if you've followed all the to-do's for brittle nails and need a little superficial strength? Totally understandable—see our selects below.
sundays B.04 Ridge Filler Base Coat
A long-lasting base coat that fills in any vertical nail ridges while it primes the nails for polish. Your lacquer of choice will look even on the surface (no grooves or bumps), and it simultaneously repairs the nail plate.

Paintbox Like Glass Nail Lacquer
Seal painted tips with this shiny top coat, or use the glossy formula on natural nails for a protective sheen. Part of strengthening your nails is sticking to polishes with nourishing, conditioning ingredients, and this number provides a patent-leather finish without sacrificing the health of your nails.

Orly Nail Armor
A win-win scenario with this ridge filler: On its own, the formula coaxes soft, brittle nails back to life—and when you apply it under polish, you'll have a flawless color payoff.
Nail Armor, Orly ($12)
This super-nourishing nail treatment is filled to the brim with nail-healthy actives: There's glycolic acid (which research has shown can help with restoring nail strength), malic acid, and lactic acid, to gently exfoliate and rejuvenate the nail plate; then there's a host of antioxidants—vitamins C, E, and B5—to hydrate and protect. Swipe it on whenever your nails need some extra love.
HyperRepair, JinSoon ($22)
Rooted Woman Foundation
A base coat formulated with prickly pear water, coconut, and castor oil that's deeply hydrating and replenishing. White spots, where?

Côte Growth with Garlic Base Coat
Remember when we mentioned garlic as a clean nail-strengthening ingredient? That's because it has antifungal and antibacterial properties that experts have claimed can help aid nail-growth. As Mary Lennon, co-founder of Côte, once told us, "Garlic is naturally fortified with selenium... This protects the body from damage caused by free radicals and infection and basically assists in improving nail growth and health."

tenoverten The Rehab Reparative Base Coat
This strengthening base coat contains celery seed extract, which may have antioxidant properties, according to one study, tea tree oil (a natural antiseptic), and horsetail extract—which has been found to help manage nail psoriasis. If you're in the market for some major recovery (you're doing some damage control from gel or acrylics, perhaps), this is your go-to.

Butter London Victoria Plum Jelly Preserve Strengthening Treatment
This treatment dries down to a sheer plum color, for those in need of some nail repair who can’t bear the thought of leaving nails, well, bare. Along with the jelly-like hue, it has hydrolyzed keratin, tea tree oil, antioxidant-rich açai berry, and vitamin E to replenish, moisturize, and protect.

ella + mila Damage Control Nail Strengthener
Another number with horsetail, which as we mentioned has some nail-healing properties. The ingredient also is antimicrobial, rich in antioxidants, and a potent anti-inflammatory—a clear winner in nail care.

Zoya Get Even Ridge Filler Base Coat
This ridge filler evens out texture with ease, and it even helps bind flakes on the free edge (bye, peeling nails). A mainstream clean classic that doesn't disappoint.
