strengthen nails: Key takeaways
To strengthen nails, focus on both short-term remedies and identifying any underlying causes. Brittle nails can result from nutrient gaps, repeated chemical exposure, or medical conditions such as hypothyroidism, so treating the root cause often gives the best results.
Remedies that commonly help include taking a biotin supplement when appropriate, boosting nail hydration, eating a protein- and nutrient-rich diet, reducing frequent manicures, using nail oil and lotion, and protecting nails from harsh chemicals. If home care doesn’t improve your nails, consult a healthcare professional — especially before starting supplements or making major diet changes.
These practical nail care tips can be added to your routine to encourage healthy nail growth and stronger, less brittle nails.
12 tips to strengthen nails
1. Take a biotin supplement
Biotin (vitamin B7 or vitamin H) is a water-soluble B vitamin that supports nail and hair strength and helps the nervous system function. Because the body doesn’t store water-soluble vitamins, you need a regular dietary supply. Biotin is found in foods such as sardines, cooked eggs, and legumes, and many people choose a B-complex or biotin supplement for extra support.
Check with your healthcare professional before starting biotin for nails, especially if you take medications or have health conditions.
2. Minimize prolonged exposure to water
Frequent soaking softens the nail plate and can make nails more prone to splitting and peeling. Wear rubber or dishwashing gloves when washing dishes or cleaning, and try to avoid prolonged hand submersion during baths. These small changes reduce repeated water exposure that weakens nails over time.
3. Keep nails hydrated
Nail hydration matters. Dehydrated nails are more likely to break or flake, so drinking enough water and using topical moisturizers helps maintain flexibility. Apply a hand cream after washing hands and use nail oil and lotion on the cuticles and nail plate to lock in moisture regularly.
4. Eat a balanced, nutrient-dense diet
Diet plays a major role in healthy nail growth. Make sure you get adequate protein and key nutrients linked to nail health, such as zinc, iron, vitamin A, and vitamin B12. Collagen peptides and other protein-rich foods—lean beef, pork, eggs, lentils, peanuts, poultry, and black beans—can support nail strength.
Consider a multivitamin if your diet is limited, but consult a healthcare professional before starting new supplements.
5. Choose gentler nail products
Many polishes, removers, and treatments contain harsh chemicals that strip oils and weaken nails. Avoid acetone-based polish removers when possible and opt for acetone-free formulas. Seek out nontoxic nail polishes and gentler soaks.
Also be mindful of hand sanitizers and household cleaners. Alcohol-based sanitizers dry nails and skin, and cleaning products can damage nails; wear gloves during chores and use sanitizer in moderation to reduce drying effects.
6. Limit gel and acrylic nails
Gel and acrylic enhancements can give the appearance of long, strong nails but frequent use may cause peeling and thinning. If you use them, leave sufficient breaks between applications to let nails recover.
Also note that the UV light used to cure gel polish can accelerate skin aging on the hands; applying sunscreen before exposure is recommended.
7. Give nails a break from polish
Constantly covering nails with polish—even nontoxic formulas—can leave them brittle. After about a week of polish, remove it using an acetone-free remover and leave nails bare for at least a week to breathe and regain strength.
8. Keep nails short
Short nails are less likely to catch, chip, or break, which helps them stay stronger. Trim and shape nails to a practical length to reduce mechanical damage and promote even, healthy growth.
9. Stop using nails as tools
Using nails to open cans, scrape, or pry increases the chance of breakage and splitting. Use the pads of your fingers or small tools (like a paper clip) instead to protect the nail edges and maintain their integrity.
10. Moisturize with lotion and nail oils
Regularly applying hand cream and cuticle oil helps maintain nail hydration and elasticity. After removing polish or washing hands, massage a lotion into the nails and cuticles. Nail oil and lotion can reduce peeling and support smoother, stronger nails when used consistently.
11. File nails correctly
Filing back-and-forth can fray the nail edge. File in one direction with a fine-grit file and avoid over-filing the sides, which can thin and weaken the nail. Gentle shaping helps prevent splits and preserves strength.
12. See a dermatologist when needed
If you’ve tried multiple home remedies for several weeks without improvement, consult a dermatologist or other clinician. Persistent thinning, pronounced brittleness, or changes in nail color or texture may signal an underlying condition that requires medical evaluation. A professional can review your routine, check for nutritional or health-related causes, and prescribe stronger, targeted treatments if necessary.
The bottom line
Your nails reflect overall health and habits, and many useful changes can strengthen nails over time. Focus on nail hydration, avoid harsh chemicals like acetone when possible, follow nail care tips such as keeping them short and filing properly, and consider biotin for nails only after consulting your doctor. If home care doesn’t help, see a healthcare professional to rule out medical causes and get tailored treatment.
