What Is a Nail Strengthener?
Think of a nail strengthener as a personal trainer for your nails. It’s a targeted treatment—usually a polish, serum, or base coat—designed to reinforce weak, damaged, or thin nails. Unlike regular polish, these formulas are packed with powerhouse ingredients (hello, keratin and biotin!) that help rebuild, hydrate, and protect. The result? Nails that are less likely to split, peel, or break—so you can rock your next mani with confidence.
How Do Nail Strengtheners Work?
They penetrate the nail plate to:
✔️ Repair cracks and splits (goodbye, peeling layers!)
✔️ Lock in moisture (dry, brittle nails don’t stand a chance)
✔️ Protect against future damage (from polish removers, water exposure, etc.)
Key Ingredients to Look For
- Keratin: The building block of strong nails.
- Biotin: Supports growth and resilience.
- Argan Oil: Deeply hydrates and nourishes.
- Hydrolyzed Wheat Protein: Repairs and strengthens.
- Calcium: Adds density to thin nails.
Nail Strengthener vs. Nail Hardener: What’s the Difference?
It’s easy to mix these up, but here’s the scoop:
- Nail Hardeners stiffen the nail plate, making it less bendy—but sometimes too brittle.
- Nail Strengtheners focus on nourishing and building flexibility, which helps prevent breakage in the long run.
| Strengthener | Hardener | |
|---|---|---|
| Best For | Weak, peeling nails | Soft, bendy nails |
| Effect | Flexible strength | Rigid firmness |
| Long-Term? | Yes (nourishes) | No (temporary fix) |
Who Should Use a Nail Strengthener?
✔️ You if…
- Your nails peel or split easily
- You’re recovering from gel/acrylic damage
- You want longer natural nails (without extensions)
❌ Skip if…
- Your nails are already strong (lucky you!)
- You need instant rigidity (e.g., for guitar players)
How to Use Nail Strengtheners for Best Results
1️⃣ Prep nails (remove polish, lightly buff).
2️⃣ Apply 1-2 thin coats (let dry between layers).
3️⃣ Reapply every 2-3 days for 2 weeks.
4️⃣ Follow up with cuticle oil (try jojoba + vitamin E).
💡 When will you see results? Most clients notice less peeling in 1 week—full strength takes 4-6 weeks.
DIY Nail Strengthening Treatments

1. Homemade Cuticle Oil: Nourish Your Nails Naturally
Making your own cuticle oil is easy, affordable, and incredibly effective for keeping nails and cuticles healthy. Here’s a simple, salon-worthy recipe you can whip up at home—plus tips on why it works and how to use it for the best results.
Why Use Cuticle Oil?
Cuticle oil isn’t just a luxury—it’s a nail health essential. Regular use helps:
- Hydrate and soften dry, cracked cuticles
- Strengthen brittle nails and prevent breakage
- Create a protective barrier against environmental damage
- Support healthy nail growth by stimulating blood flow
As Formula Botanica notes, “Cuticle oils are the most popular nail care treatments. They are moisturizing products typically derived from vegetable oils, plant extracts, vitamins, and some aromatherapeutic compounds such as essential oils. Regular nail treatment may bring long-term benefits in the quality and visual appearance of the nail and surrounding skin.”
Salon 1150’s DIY Cuticle Oil Recipe
You’ll need:
- 1 tablespoon jojoba oil (deeply hydrating and absorbs quickly)
- 3 drops vitamin E oil (antioxidant and nail strengthener)
- 1 drop lavender essential oil (soothes and adds a relaxing scent)
Optional swaps:
Try hemp seed, sweet almond, or grapeseed oil as a base. You can also add a drop of tea tree oil for extra antimicrobial benefits, or a dash of calendula extract for soothing sensitive skin.
How to use:
- Mix all ingredients in a small glass bottle or roller.
- Apply a drop to each nail and cuticle.
- Massage gently for 1–2 minutes to boost absorption and blood flow.
- Use nightly (or after every hand wash in dry weather) for best results.
Bottom line:
DIY cuticle oil is a simple, natural way to keep your nails and cuticles looking their best—no salon visit required!
2 Eat for Stronger Nails: A Simple, Science-Backed Method
According to the American Academy of Dermatology, what you eat can make a real difference in nail health. Here’s how to build a nail-strengthening meal plan:
- Prioritize Protein
Nails are made of keratin—a tough protein. Without enough protein, nails can become weak and slow to grow.
- Try: grilled salmon, lentil soups, Greek yogurt, or a handful of almonds.
- Boost Your Biotin
Biotin (vitamin B7) is famous for supporting nail growth and strength.
- Snack on: eggs, almonds, sweet potatoes, or sunflower seeds.
- Don’t Forget Zinc
Zinc helps your body build healthy new cells—including nail cells.
- Add: spinach to your salads, oysters to your dinner, or pumpkin seeds to your breakfast bowl.
Pro tip:
Pair these nutrients with plenty of water for hydration—dehydration is a sneaky culprit behind brittle nails
Quick Recap:
- Protein = building block
- Biotin = growth booster
- Zinc = repair and renewal
- Water = flexibility and shine
Eat well, and your nails will show it—inside and out!
FAQs About Nail Strengtheners
Can I use nail strengthener under regular nail polish?
Yes, you can absolutely use a nail strengthener under regular nail polish—and it’s actually a smart move for most people looking to protect and fortify their nails. As professional nail artist Daring Lily explains, “Using a nail strengthener as a base coat can be an excellent way to protect your nails and prevent them from becoming brittle or discolored. By applying a nail strengthener before your regular nail polish, you create a protective barrier that can prevent staining, chipping, and peeling”.
Reddit user @juleznailedit echoes this approach, sharing:
“I always use a nail strengthener as my base before color. It really helps prevent peeling and makes my polish last longer.”
Just be sure to let the strengthener dry completely before applying your color polish. This simple step can help you maintain both a gorgeous manicure and healthy, resilient nails.
How often should I apply a nail strengthener?
Start with every 2–3 days for 2 weeks. After that, weekly touch-ups can help maintain strength.
Why do my nails still peel after using a strengthener?
Peeling can stem from internal factors (diet, hydration) or external habits (like using nails as tools!). Try:
✔️ Adding a biotin supplement (10,000 mcg/day).
✔️ Wearing gloves when washing dishes.
✔️ Scheduling a hydrating nail treatment at our salon.
How long does it take for nail strengtheners to work?
You’ll typically start to see improvements in nail strength and appearance within 2 to 4 weeks of consistent use, but the most significant results often appear after 8 to 12 weeks of regular application. For example, a clinical study found that after 28 days, participants experienced about a 16% improvement in nail hardness, which increased to nearly 27% after 84 days of daily use.
Reddit user shares,
“You’re looking at 4–6 months of consistent care and maintenance, and that’s just to grow out the damage. After that, you can decide if you want to keep using it.” reference
Similarly, beauty editors at Byrdie note that most testers saw visible improvements in nail strength and reduced splitting after about 12 weeks of regular use, with some noticing changes in as little as a few weeks
What’s the #1 mistake people make with nail strengtheners?
Over-applying. Too many layers can lead to buildup and peeling. Stick to thin coats and give nails a breather every 10 days.
