Top 10 Nail Strengtheners

THE FORMULA
Deborah Lippmann's Hard Rock Nail Strengthener has a 21-free formula. That means it's completely free of the usual toxic suspects found in nail polish such as phthalates, formaldehyde resin, and silicones.

WHAT IT DOES
If you've recently had your nails destroyed by a gel manicure gone wrong, this strengthener can help return them to their former state. One reviewer says, "Before discovering this base coat, my nails would just break and be very brittle." 

THE FORMULA
Developed by dermatologists, this nail conditioner is the real deal. Its unique, patented technology binds cells together to create strong and stable nails, encouraging longer growth by controlling splitting, peeling, cracking, chipping, and breakage.

WHAT IT DOES
This is an excellent choice for those struggling with cosmetic nail problems caused by trauma or injury, such as onychomycosis and psoriasis.

THE FORMULA
Vitamin B7, also known as biotin, is the key ingredient behind this strengthener from Nail-Aid. Biotin helps improve the protein infrastructure of keratin (the main component of nails), making them stronger and less prone to splitting or breaking.

WHAT REVIEWERS ARE SAYING
"My nails used to be thin and weak. They would chip and crack often. I could never have long nails that were real. I’ve been using this consistently for a few weeks now and my nails are strong and growing! I just brush it on once a week when I have time and I’m finally getting the nails I’ve always wanted."

THE FORMULA
The Si-Nails Serum Nail Strengthener promises noticeable results in just 14 days. It was created to boost nail growth and reduce visible damage. Its formula contains hyaluronic acid, which helps keep cuticles moisturized and healthy. 

WHAT IT DOES
If your nails are peeling or splitting, this strengthener will infuse them with the hydration and nutrients needed to help them get their strength back.

THE FORMULA
This is technically a nail hardener, but it strengthens nails by creating a shield of micro diamonds and titanium. Use it as a base before applying a polish or gel or apply it on its own to put breakage to bed. 

WHAT REVIEWERS ARE SAYING
"I have always struggled with weak nails in the past. My nails would grow a bit, then chip within a matter of days. Now, I have long nails after just one application!"

THE FORMULA
Another option from Sally Hansen, the Hard As Nails Strengthener Solution only slightly differs from the Diamond Strength version. While the latter is used to create a long-lasting shatterproof shield, this version contains film formers that create a protective barrier over your nails. 

WHAT REVIEWERS ARE SAYING
"In terms of value, this a great budget-friendly product that effectively strengthens weak nails and helps prevent chipping. Overall, it's a reliable choice for maintaining nail health at a reasonable price point."

THE FORMULA
This nail strengthener features a formula packed with naturally derived ingredients. There's celery seed extract, an antioxidant known to improve nail thickness, and rosemary and lavender to provide a dose of nourishing hydration. 

WHAT IT DOES
Pretty bottle aside, shoppers love this nail strengthener for its lasting power. Unlike many formulas, you only need to use this one once a week to see results.
