Brittle nail tips: how to reduce splitting and breakage

The nail tip is the oldest part of the nail, so it has had the most contact with water, soap, cleaning products and friction. Frequent soaking followed by drying can make layers separate. Long nails also have more leverage when they catch on clothing or objects. Peeling may be made worse by filing back and forth, biting, or pulling away a loose layer. If the tip changes along with thickening, unusual colour, crumbling or material beneath the nail, an infection such as nail fungus is one possibility and should be assessed rather than assumed.

Trim the free edge before it catches, then smooth it with a gentle file. File in one direction and leave the cuticle intact. Use gloves for cleaning, gardening and food preparation that keeps your hands wet. After handwashing, pat dry and massage an unscented cream or ointment over the nail tips and surrounding skin. Use nails as shields, not tools, and avoid opening cans or scraping labels with them. Remove polish gently and take breaks from buffing or extensions if the surface is thin or sore. These steps protect new growth while damaged length gradually grows out.

Book an appointment if splitting continues, spreads to multiple nails, or is accompanied by persistent tenderness or nail separation. Seek prompt care for swelling, warmth, drainage, severe pain, or a new dark mark. An injury that causes bleeding under the nail or the nail to lift may need timely attention. A clinician can distinguish mechanical damage from infection or a skin disorder and advise whether testing is needed.

Does the pattern suggest simple tip damage or another nail problem? How short should I keep the nails? Which products should I avoid, and should a sample be tested?
