Chemotherapy-induced nail and skin changes in breast cancer
Chemotherapy can darken, ridge or loosen the nails and make skin dry, darker or sun-sensitive. These changes are common with several breast cancer drugs, including the taxanes, and most improve after treatment. This page explains, in general terms, what to expect, how to care for nails and skin, and when to call.

The short answer
Why does chemotherapy change the nails and skin?
Nails and skin are made by cells that divide quickly, so chemotherapy affects them as it affects hair. Nails may darken, develop ridges or lines, become brittle, or occasionally lift from the nail bed. Skin can become dry, darker, itchy or sensitive to sunlight. These changes are common with several breast cancer drugs, including the taxanes, and most improve after treatment ends.
Why it is worth paying attention
Most nail and skin changes are cosmetic and settle with time. A few, such as a nail lifting with pus underneath or a painful rash, need prompt treatment to prevent infection.
What helps
Gentle daily care, moisturising, sun protection, keeping nails short and clean, and in some centres cooling the hands and feet during infusion. Reporting problems early lets your team treat them before they worsen.
Who should take extra care
People with diabetes, poor circulation, existing skin conditions or jobs that keep their hands in water. Mention these to your team before treatment begins.
This page gives general information only. Your oncology team can advise on changes you notice.Nails
The nail changes people most often notice
Nails grow slowly, so changes may appear weeks into treatment and take months to grow out.
Darkening and lines
Nails may turn darker, or show bands and lines across them that mark each cycle. These are harmless and grow out gradually once treatment finishes.
Brittle or ridged nails
Nails can become thin, split easily or develop ridges. Keeping them short and wearing gloves for household work helps protect them.
File gently rather than cutting close.Nails lifting
Sometimes a nail partly separates from the nail bed. It can be sore and may collect fluid underneath. Tell your team, as it may need care to prevent infection.
Infection around the nail
Redness, swelling, warmth or pus around a nail needs prompt attention, particularly if your white cell count is low.
Contact your team if
- A nail is red, hot and swollen
- There is pus or a bad smell
- You also have a fever
Skin
Skin changes during treatment
Skin reactions range from mild dryness to rashes that need treatment.
Dryness and itching
Very common. A fragrance-free moisturiser used several times a day, lukewarm rather than hot baths, and soft cotton clothing make a real difference.
Darkening of the skin
Some drugs cause patches of darker skin, especially on the hands, feet or along veins used for infusion. This usually fades slowly after treatment.
Sun sensitivity
Skin may burn more easily. Cover up, stay in shade during the hottest hours and use a broad-spectrum sunscreen on exposed skin.
Sore hands and feet
Redness, swelling and soreness of the palms and soles can occur with some drugs. Report it early, because the dose may need adjusting.
Daily care
A simple routine for nails and skin
Keep nails short and clean
Trim straight across and file gently. Avoid cutting cuticles, false nails and harsh removers, which can let infection in.
Moisturise hands, feet and cuticles
Use a plain, unscented cream several times a day, especially after washing. Rub a little into the cuticles too.
Protect your hands
Wear gloves for washing up, cleaning and gardening. Water and detergents dry the skin and soften the nails.
Choose comfortable footwear
Well-fitting shoes with room for the toes reduce pressure on sore or lifting toenails. Avoid walking barefoot.
Check daily and report changes
Look at your nails and skin each day. Photographs can help you show your team how things have changed between visits.

Words you will hear
The vocabulary, in plain language
- Nail bed
- The skin beneath the nail that the nail sits on.
- Onycholysis
- The nail lifting away from the nail bed. It usually grows out once treatment ends.
- Paronychia
- An infection of the skin around a nail, causing redness, swelling and sometimes pus.
- Hand-foot syndrome
- Redness, soreness and peeling of the palms and soles with some drugs.
- Hyperpigmentation
- Darkening of the skin or nails, which usually fades slowly after treatment.
- Cooling during infusion
- Frozen gloves and socks worn during some infusions to reduce nail and skin effects.
Being straight with you
What to expect honestly
Nail and skin changes are rarely dangerous, but they can be upsetting and uncomfortable, especially because they are visible. Many people find the changes to their hands affect their confidence more than they expected.
Nails take time to recover
Fingernails grow slowly and toenails even more slowly. Lines and darkening may take many months to grow out after treatment ends. Patience and gentle care are usually all that is needed.
Nail polish is a personal choice
Some people find a dark polish helps hide changes and protects the nail from light. Use a gentle, acetone-free remover, and stop if the nail becomes sore or lifts.
Infection is the thing to watch
A sore, swollen, hot nail fold can become serious if your white cell count is low. Treat it as a reason to call rather than something to wait out.
What this page cannot tell you
It cannot tell you which changes your own drugs are likely to cause. Ask your team what to watch for with your regimen.
Feeling like yourself
When visible changes affect confidence
Hands are always on show. Darkened nails or dry, discoloured skin can make treatment feel visible in a way that is hard to hide at work, at family gatherings or when greeting people.
Practical ways to feel more at ease
Some people use a dark or neutral nail polish over healthy nails, wear light cotton gloves outdoors, or choose sleeves that cover darkened skin on the arms. Small choices like these can restore a sense of control.
Talking about it
It is normal to feel self-conscious. Mention it to your team, who hear this often and may suggest practical products or support. Friends and family usually notice far less than you fear, and most changes fade steadily after treatment ends.
Commonly believed
What people assume about nail and skin changes
Dark nails mean something is seriously wrong.
Darkening and lines across the nails are common, harmless effects of chemotherapy that grow out with time. Redness, swelling or pus is different and should be reported.
Home remedies like turmeric paste will heal a sore nail.
Home pastes can irritate damaged skin and hide early signs of infection. Keep the area clean and dry, and ask your team what to apply.
A lifting nail should be pulled off.
Do not pull it off. Pulling can cause pain, bleeding and infection. Keep it trimmed short and protected, and let your team advise.
Once treatment ends, nails look normal straight away.
Nails need months to grow out fully, and toenails even longer. Improvement is steady but slow, which is expected.
Questions we are asked
Common questions about nails and skin
Which breast cancer drugs affect the nails most?
Taxanes such as docetaxel and paclitaxel are commonly linked with nail changes, and several other drugs can affect skin and nails too. Your team can tell you what to expect with your own regimen.
Do frozen gloves help nails?
Some studies suggest cooling the hands and feet during taxane infusions can reduce nail changes. It can be uncomfortable and is not offered everywhere. Ask whether it is available where you are treated.
Can I get a manicure or pedicure?
It is safest to avoid salon treatments that cut cuticles or use shared tools, since they can cause infection. Gentle care at home, with clean tools, is a better choice during treatment.
What moisturiser should I use?
A plain, fragrance-free cream or ointment used often is usually best. Ask your team before using creams with strong acids, perfumes or herbal ingredients.
Is it safe to go out in the sun?
Yes, with care. Some drugs make skin burn more easily. Cover up, use shade in the hottest hours and apply sunscreen to exposed skin.
My skin has gone darker. Will it fade?
Usually, gradually, over months after treatment ends. Sun protection helps it fade. Tell your team if patches are painful, raised or spreading.
When is a nail problem urgent?
If there is spreading redness, pus, severe pain or a fever, contact your team the same day. Infection can become serious when your counts are low.
Where can I read about my own drug?
Your oncology team will give you written information about each drug in your plan, including skin and nail effects. Use that as your main reference.
