When you’re fighting cancer, your focus is on healing — not on your nails. Yet did you know painful nail damage is often referred to as the 2nd most prevalent side effect behind hair loss for certain types of chemotherapy treatments? And up to 80% of people notice painful, brittle, infected or peeling (curving or detached) nails once certain types of chemotherapy begins. These small changes can become daily reminders of treatment and, for some, an unexpected source of pain or frustration.
What you’re experiencing has a name: chemotherapy-induced nail toxicity, sometimes called "chemo nails." Understanding why it happens can make the difference between feeling helpless and feeling in control.
Why Do Chemo Nails Happen?
Chemotherapy works by targeting rapidly dividing cells — the fast-growing cancer cells that your doctors are fighting. But other cells in your body also divide quickly, including those in your hair follicles, skin, and the nail matrix (the "factory" beneath the cuticle that produces each new nail).
When chemo slows or damages those nail-forming cells, the result can be:
-
Nails that grow thinner, weaker, or with ridges
-
Tenderness, discoloration, or separation from the nail bed
-
Inflammation or infection around the edges
This isn’t just cosmetic. For many, it can cause a significant decline in your quality of life. Chemo nails can cause real pain, infection and limit normal activities — buttoning a shirt, typing, cooking, writing and so much more.
🧬 The Science in Simple Terms
Medical studies show that chemotherapy can interrupt the supply of keratin (the protein that forms nails) and temporarily reduce blood flow to the fingertips and nail beds. Less nourishment = slower, weaker nail growth.
In plain English: your nails are trying to rebuild while the medicine that saves your life also makes that rebuilding harder.
Why Early Nail Care Matters
The good news is that nail damage isn’t inevitable. Many oncology centers now include proactive nail-care recommendations because prevention and gentle protection can:
-
Reduce nail pain and breakage
-
Lower the risk of infection
-
Help patients feel more confident and comfortable
Starting a protective routine early — ideally before or at the start of chemotherapy — gives your nails the best chance to stay healthy throughout treatment. But even if you’ve already begun or finished therapy, it’s never too late to help your nails recover and grow strong again.
The great news? There’s finally a 100% natural, clinically proven solution developed in the UK by oncologists, dermatologists, and botanical experts — Polybalm — the breakthrough balm that protects, restores, and strengthens nails through every stage of treatment.
