Brittle, ridged, or peeling nails are very common and are usually linked to everyday damage rather than a serious illness. Repeated exposure to water, cleaning chemicals, frequent handwashing, and cosmetic treatments like gel or acrylic nails can all weaken the nail structure over time.

Nails are made of keratin layers that can separate when they are stressed. This leads to peeling at the tips, splitting, or vertical ridges. In most cases, these changes develop slowly and affect multiple nails, often becoming more noticeable with age or frequent moisture exposure.

Home remedies like soaking nails in olive oil can help temporarily improve dryness by moisturizing the nail plate and surrounding cuticles. This may make nails look smoother and feel less brittle, but it does not repair the internal structure of the nail or permanently remove ridges.
