How to Keep Your Nails Healthy: A Simple Guide

Healthy nails don't need an elaborate routine — they need protection from the everyday things that damage them, plus a few good habits. Most nail problems people bring to a dermatologist come down to over-treatment, harsh products, or water exposure, all of which are avoidable. Here's the simple version.

Keep them clean and dry

Nails and the skin around them do best clean and dry. Prolonged moisture is a leading cause of brittle, peeling nails and creates conditions for fungus to take hold (PMC, 2020). Wear gloves for washing dishes, cleaning, and gardening — this one habit prevents a lot of nail damage.

Trim them properly

• Trim clean and after a shower, when nails are softer and less likely to split.
• Toenails: cut fairly straight across to help prevent ingrown toenails. Fingernails can follow a gentle curve.
• Don't cut too short, file rough edges gently in one direction, and disinfect your clippers regularly (AAD).

Leave your cuticles alone

It's tempting, but don't cut your cuticles. That little seal protects the base of your nail from bacteria and fungi — removing it invites infection and irritation. Gently push cuticles back after a shower if you like a neat look, and leave them otherwise intact (AAD).

Moisturize — nails get dry too

Treat your nails and cuticles like you treat your skin: moisturize them. Apply a hand cream or nail oil, especially after washing your hands, to keep nails flexible and less prone to splitting. Humectants like hyaluronic acid and emollients such as squalane help lock in moisture.

Go easy on manicures and removers

Frequent gel and acrylic manicures, and the acetone used to remove them, gradually thin and weaken nails. You don't have to give them up — just take breaks between sets, never peel them off (that strips the nail's layers), and moisturize afterward.

Be gentle day to day

• Don't use your nails as tools to pry, scrape, or pick.
• Don't bite or pick at nails or cuticles.
• At salons, choose clean, licensed places and make sure tools are sterilized — shared, unclean tools can spread infection.
• Support nails from the inside with a generally balanced diet; dramatic supplements are rarely the answer (see the honest take on biotin).

When to see a doctor

Good habits prevent most everyday nail problems, but not all. See a dermatologist for persistent discoloration, thickening, pain, or separation, and don't ignore a new or changing dark streak — the warning signs are covered in what your nail changes can mean. And get any non-healing area looked at in person.
