Stronger nails start with everyday habits

Why nails get weak

A nail is made of layers of keratin held together with a little water and oil. Each time your hands get wet, those layers swell, and each time they dry, the layers shrink. Repeat that dozens of times a week and they begin to loosen.

Dish soap, household cleaners and hand sanitizer make things worse by stripping away oil. Thin nails can also run in families, and most people's nails get drier and more brittle with age.

Weak nails come in two main kinds, and they need slightly different care. Soft, bendy nails usually spend too much time in water, so gloves and shorter soaks matter most. Hard, brittle nails that snap are usually short on moisture, so oil and cream do the heavy lifting.

Daily habits that add up

None of these is dramatic, and that is why they get skipped. Consistency over a few months is what shows results.

Swimmers have one more job. Chlorine and salt water both pull moisture out of the nail, so in South Florida, a rinse and a little oil after the pool or the beach is worth making routine.

• Pull on gloves before doing dishes or scrubbing anything
• Rub oil or thick cream into your nails at bedtime and after washing
• Keep nails short and rounded so corners do not catch
• File in one direction with a fine file, never sawing back and forth
• Use a coin or a tool to open things, never a fingernail
• Follow hand sanitizer with hand cream
• Dry your hands fully after washing, including around each nail

Food, biotin and strengthening polishes

Nails are built from what you eat, so regular protein and iron-rich foods are a sensible base. Biotin has small studies behind it for brittle nails, with mixed results. High doses can interfere with some blood tests, so tell your doctor before starting it. A crash diet or a serious illness can show up in your nails months later, because new growth records what your body was going through when it formed.

Over-the-counter hardeners can feel helpful at first. With long use, some make nails stiff enough to snap, and some cause irritation around the nail. Treat them as a short-term aid, and stop if the skin reddens.

How salon services can help or hurt

Heavy filing, peeling off old product and back-to-back sets with no care in between all thin the nail. Whatever you wear, gentle removal matters more than the product. Take off with a service starts at $10 at Element and adds about 15 minutes.

Builder gel is a thicker gel layer that keeps nails from bending, which gives a weak tip a chance to grow past the fingertip. Think of it as protection while your own nail grows, since the nail underneath stays the same. A Builder Gel Fill starts at $60 and takes about 60 minutes when it needs refreshing.

When to see a doctor

Sudden or unusual changes deserve a medical opinion, because they can be linked to things that no manicure can address. A dark streak is worth a prompt visit. Hold off on polish and enhancements until a doctor or dermatologist has had a look, since color can hide what they need to see.

• A nail lifting away from the skin
• Pits, deep ridges or new lines across the nail
• Yellow, green, dark or streaked color
• A nail curving like a spoon or thickening quickly
• Pain, swelling or pus
• No improvement after a few months of careful habits

Questions guests ask

How long does it take to strengthen nails?

Expect two or three months before you notice a change at the tip. Fingernails grow only about three millimeters a month, so the stronger nail you are building takes its time to reach the edge.

Does gel polish make nails stronger?

Ordinary gel color adds a little rigidity but very little real strength. Builder gel is thicker and gives far more support. Neither changes the nail underneath, and both can leave it weaker if they are peeled off.

Should I take a break from manicures?

There is no set schedule. A break makes sense if your nails feel sore, thin or bendy. If they feel fine and your removals are careful, you may not need one.
