Nails may seem like a small detail, but they play an essential role in protecting fingers and toes. Keeping them healthy is part of good hygiene for kids of all ages. Whether your child is an infant, toddler, tween, or teen, here’s what parents need to know about nail care and strengthening.
Nail Basics
Fingernails and toenails are made of keratin, the same protein in hair and skin. Healthy nails are smooth, strong, and slightly curved. Nail problems—such as peeling, splitting, or brittleness—can result from injury, infection, or poor nutrition.
Daily Nail Care
Routine nail hygiene helps prevent infection and keeps nails looking their best.
Keep nails clean and trimmed. Short nails are less likely to trap dirt or bacteria. Use clean clippers or nail scissors and cut straight across to prevent ingrown nails.
Avoid biting or picking. These habits can damage the nail bed and introduce germs. Encourage kids to use a nail file instead.
Moisturize regularly. Dry nails break more easily. After washing hands or bathing, apply a gentle moisturizer to nails and cuticles.
Nail Strengthening Tips
Most healthy kids don’t need fancy nail treatments, but proper habits can keep nails strong:
Good nutrition matters. A balanced diet with plenty of protein, fruits, vegetables, and whole grains supports nail health. Biotin-rich foods like eggs, bananas, and nuts may help strengthen nails.
Limit harsh chemicals. Acetone-based nail polish removers and constant use of nail polish can dry out nails. Choose gentle products when possible.
Protect nails from damage. Well-fitting shoes can prevent ingrown toenails and injuries, while wearing gloves during chores or cold weather helps protect fingernails.
Nail Trauma
Kids are active; sometimes, fingers or toes get caught in doors, stubbed, or smashed. Mild bruising under the nail (a dark purple spot) is common and usually heals as the nail grows out.
Watch for pain and swelling. If your child can’t bend a finger or toe, or if the pain seems severe, have it checked by a doctor.
Don’t try to drain blood at home. This should only be done by a healthcare provider if necessary.
A loose or lifted nail may fall off. New nail growth will replace it over several weeks to months.
Common Nail Conditions
Several nail issues pop up frequently in kids:
Ingrown toenails. These can occur when nails are cut too short, or shoes are too tight. Soaking the foot and wearing roomy shoes can help.
Nail fungus. This is common in toenails and may cause thick, yellow, or brittle nails. Treatment typically requires a prescription.
Nail biting and thumb sucking. These activities can damage and change the nail’s appearance or growth. Talk to your pediatrician for advice on helping your child break these habits.
When to See a Doctor
Most nail issues resolve with basic care, but reach out to your child’s healthcare provider if you notice:
Redness, swelling, or pus around the nail
Persistent pain or a nail that lifts from the nail bed
Discoloration, thickening, or unusual shape that doesn’t go away
Final Thoughts
Healthy nails are more than cosmetic—they’re part of overall wellness. With daily care and attention, your child’s fingernails and toenails can stay strong, clean, and problem-free.
