If your nails are constantly peeling, breaking or just refusing to grow past a certain point, you’re not alone—nail damage is incredibly common, especially if you regularly wear polish, gel or press-ons. What’s more confusing is that the solution seems simple. Use a nail strengthener, right?

But if you’ve ever actually tried one, you know it’s not that straightforward. Some formulas feel like they make your nails harder, but then they snap. Others promise repair but don’t seem to do much at all. And then there’s the bigger question: are nail strengtheners even doing anything, or are they just another step that sounds good in theory?

Part of the issue is that “weak nails” can mean a lot of different things. For some people, it’s peeling and flaking. For others, it’s bending, splitting or just never growing. And depending on what’s actually going on, the product that works for someone else might not work for you.

So, we spoke with celebrity manicurists to understand what actually makes a nail strengthener worth using. The biggest takeaway? These products can work—but only if you understand what they’re designed to do, and what your nails actually need. Some formulas reinforce, others hydrate and the best ones do both. And just as important as the product itself is how (and how consistently) you use it.

Ahead, everything to know before you buy—and the nail strengtheners that experts actually recommend.

Short answer: yes—but they’re not a quick fix. “Nail strengtheners do not repair instantly—they support new growth and protect,” says Jacqueline Pham, a celebrity manicurist who has worked with Jennifer Lopez and Halle Berry.

According to JinSoon Choi, whose clients include fashion week regulars, the most effective formulas don’t just harden the nail—they improve both strength and flexibility, which helps prevent breakage. That distinction matters. Overly hard nails can actually snap more easily, while overly soft nails can peel or bend—the goal is balance.

And in many cases, what people think is “weakness” is actually dehydration. “Many people think their nails are weak because they break easily, but often they’re actually just very dry,” Choi explains. “That lack of moisture causes cracking.”

Top Nail Strengtheners

The best nail strengtheners don’t rely on just one type of ingredient—they combine reinforcing and conditioning elements. Choi recommends looking for exfoliating acids like glycolic, lactic and malic acids to smooth the nail surface, along with vitamins C, E and panthenol to maintain flexibility.

Pham points to keratin as a key strengthening ingredient, since it reinforces the structure of the nail itself. Meanwhile, manicurist Nettie Davis—who has worked with Zendaya, Janelle Monáe and Gabrielle Union—highlights ingredients like calcium, biotin, glycerin and hydrolyzed wheat protein for long-term strength and flexibility.

The common theme: strong nails aren’t just hard—they’re hydrated.

What’s the Best Way To Apply Nail Strengtheners?

Application is where a lot of people go wrong. “You want to apply on clean, oil-free nails,” says Choi. “For weak or damaged nails, I recommend two coats on bare nails.”

Consistency matters just as much. Pham suggests removing and reapplying at least once a week, while Davis recommends adding a fresh coat every couple of days if you’re actively trying to repair damage. If you’re using it as maintenance, you can wear it under polish. But if you’re in recovery mode, simpler is better.

Yes—but it depends on your goal. If your nails are relatively healthy, strengtheners can double as a base coat and help your manicure last longer. Olivia Van Iderstine, Olive & June’s mani trend expert, notes that some formulas even improve polish adhesion.

But if your nails are damaged, layering too many products can work against you. Davis recommends letting the strengthener do its job on its own first: “A strengthener should focus on nourishing the nail. Treatment first, longevity second.”

12 Best Nail Strengtheners, Tested by Celebrity Manicurists

Best Overall: JINsoon HyperRepair Treatment Base Coat, $22

If you want a formula that does a little bit of everything well, this is the one experts consistently point to. It’s designed to strengthen while maintaining flexibility—something Choi emphasizes as essential to preventing breakage. “A good strengthener improves both strength and flexibility, so nails don’t become brittle,” she says.

She recommends this formula specifically because it reinforces the nail without making it overly hard, which can actually lead to snapping. It’s especially useful if your nails are recovering from gels or frequent polish removal and need to be brought back to a healthy baseline.

Best for Peeling Nails: essie Hard to Resist Nail Strengthener, $11

Ulta

Peeling nails usually aren’t just weak—they’re dehydrated and breaking down at the surface. This formula leans more into repair and conditioning, using strengthening technology alongside hydrating ingredients to help smooth layers and reduce flaking over time. According to Choi, it’s less about creating a hard shell and more about improving the overall condition of the nail so it stops splitting in the first place.Treatments like this work well for peeling specifically because they focus on flexibility and moisture—not just reinforcement—making them a better long-term fix for nails that won’t stop flaking.

Best for Growth: Olive & June Advanced Nail Strengthener, $15

Amazon

If your goal is longer nails—not just stronger ones—this upgraded version is worth considering. It’s designed to protect against chipping and breakage while supporting growth, which makes a difference if your nails tend to break before you see real length.

Van Iderstine notes that this is ideal “when you want to achieve your longest, strongest nails,” with many users seeing improvement quickly. It layers easily under polish, so you can keep your routine intact while still treating your nails.

Best for Damaged Nails: Color Street Nail Strengthener, $13

Color Street

When nails feel compromised—whether from over-filing, gel removal or general wear—this formula focuses on rebuilding strength. It’s packed with keratin and vitamins, which help reinforce the nail structure and support healthier regrowth over time.

Pham recommends keratin-based formulas like this one because they directly strengthen the nail itself. It’s a good option if your nails feel thin, weak or easily damaged.

Best for Thin Nails: Nailtiques Formula 2, $18

Amazon

This is one of those “if you know, you know” products that professionals swear by. It’s especially effective for thin, peeling nails, helping to gradually rebuild strength without making them feel heavy or stiff.

Davis calls this one of the “gold standards,” adding, “The secret to strong nails is sticking to the legends.” If your nails won’t grow past a certain point, this is often the one that makes the biggest difference.

Best for Weak Nails: Nail Tek Intensive Therapy 2, $13

Amazon

Soft, bendy nails require a slightly different approach, and this formula is designed with that in mind. It helps reinforce the nail structure while reducing peeling and splitting, making nails feel more stable over time. Davis recommends this alongside Nailtiques as a tried-and-true option. It’s particularly helpful if your nails feel flexible but fragile, rather than dry or brittle.

Best Base Coat: OPI Nail Envy Original, $20

Amazon

If you want a strengthener that fits seamlessly into your existing routine, this is one of the easiest options, says Natalie Minerva, celebrity nail artist who has worked with Demi Lovato. It doubles as a base coat, using hydrolyzed wheat protein and calcium to reinforce nails while prepping them for polish. You can use it under any manicure, which makes it easier to stay consistent.

Best Budget: Sally Hansen Hard As Nails Strengthener, $3

Amazon

This is the classic drugstore pick that’s been around for years—and for good reason. It focuses on strengthening and protecting against everyday wear, making it a reliable option if your nails are generally healthy, but prone to occasional breakage, says Davis. If you’re new to nail treatments or just want something affordable to start with, this is an easy entry point.

Best With Color: Essie Treat Love & Color, $9

Amazon

If you don’t want to go fully bare while treating your nails, this is a great compromise. It combines strengthening ingredients with a sheer wash of color, so your nails look polished while still improving over time. This is especially useful if you’re trying to repair damage but still want your nails to look finished day-to-day, says Davis.

Best Hydrating Formula: Butter London Nail Rescue Basecoat, $15

Amazon

Not all “weak” nails are actually weak—sometimes they’re just dry. This formula focuses on hydration, helping improve flexibility and reduce brittleness so nails are less likely to crack. As Choi points out, dryness is often the real issue behind breakage. If your nails feel rough or dehydrated, a formula like this addresses the root cause instead of just reinforcing the surface.

Best for Splitting Nails: Orly Nail Defense, $11

Sally Hansen

If your nails tend to split or peel at the edges, this formula creates a protective layer that helps prevent further damage. It reinforces the nail without making it feel thick or heavy, which makes it easy to wear consistently. According to celebrity nail artist Elle Gerstein who has worked with Julianne Moore, it’s a solid option if your nails are mostly healthy but prone to breaking from everyday wear.

Best Luxury: Dior Nail Glow, $34

Sephora

This is less of a heavy-duty treatment and more of a polished, elevated option. According to celebrity nail artist Ami Streets who has worked with Ella Purnell, it enhances your natural nail color with a subtle pink tint while offering light strengthening benefits, so your nails look better instantly. If you want something that feels more like a beauty product than a treatment step, this delivers both aesthetics and a bit of care.
