What Should You Know About Flaky, Peeling Nails?

The nail plate is made of layers, so the free edge can split or lift when it is repeatedly softened by water and then dried. Frequent handwashing, cleaning chemicals, swimming, biting, picking, and using nails as tools can add stress. Nail polish remover, gel manicures, filing, or forcefully removing product may also leave nails dry and fragile.

Changes affecting one nail may follow an injury, while changes across several nails can relate to ongoing exposure or a skin condition. A thickened, yellow, crumbly, or lifting nail can also be a presentation of nail fungus; see [Nail Fungus](/conditions/nail-fungus/) for related information. Colour change, pain, swelling, or separation from the nail bed makes an examination more useful than treating the appearance alone.

Keep nails trimmed and smooth rough edges with a fine file, moving in one direction. Wear gloves for dishwashing or cleaning, dry hands and nails carefully afterward, and apply a thick moisturiser to the nails and surrounding skin. Avoid peeling loose layers, biting, aggressive buffing, and using nails to open or scrape objects.

Give damaged nails a break from gel, acrylic, extensions, and frequent remover while they grow out. Do not cut or push back the cuticles, because the surrounding skin helps protect the nail from germs. If a product causes burning, redness, or itching, stop using it and wash the area. A clinician can check for infection, inflammation, injury, or another cause before recommending treatment.

Arrange a medical review if peeling continues despite reducing irritation, returns repeatedly, or affects many nails. Seek prompt care for increasing pain, warmth, swelling, pus, marked tenderness, or redness spreading around a nail. A dark new streak, a nail that changes shape or colour, bleeding without a clear injury, or a nail separating from its bed should also be assessed.

Bring a list of nail products and cleaning exposures, and mention recent injuries, skin rashes, new medicines, or other symptoms. Do not scrape away discolouration before an appointment, as the remaining nail may help show what is happening.

You could ask: What is the most likely reason for this nail change? Does the nail need testing for fungus or another condition? Which products or habits should I pause? What treatment is appropriate, and what changes should prompt an earlier review?
