What are nail disorders?

A fingertip diagram identifies the free edge, nail plate and cuticle.

Nail disorders include changes in colour, thickness, shape or attachment, as well as problems with the skin around a nail. They can affect fingernails, toenails or both.

Not every damaged or yellow nail has a fungal infection. Repeated wet work, injury, nail products, psoriasis and other health conditions can affect nails too. The pattern and your history help guide the diagnosis.

What change have you noticed?

A nail has a thick, yellow-brown area towards its free edge.

Thick or discoloured nails

Fungus is one possible cause, but injury or psoriasis may look similar. A sample can help confirm infection before a long course of medicine.

Explore fungal infections
A nail shows lengthwise ridges and small splits at its free edge.

Brittle nails or ridges

Frequent water exposure, chemicals, ageing or repeated trauma can contribute. New deep grooves or unexplained changes need an assessment.

Several small shallow dents appear in the nail surface.

Small pits or dents

Pitting can occur with psoriasis and some other conditions. Mention skin patches, hair changes, or joint pain and stiffness.

Understand psoriasis
A pale area extends back from the free edge where the nail has separated.

A nail lifting away

Injury, infection and psoriasis can cause lifting. Do not dig underneath or glue the loose area back down; get advice on protecting it.

The skin along the sides and base of a nail is swollen and irritated.

Sore skin around the nail

An irritated nail fold may relate to wet work, picking, an ingrown nail or infection. Pain, warmth and pus need prompt attention.

A dark lengthwise band runs along a nail.

A new or changing dark band

Many pigment bands are benign, but a new or changing band needs a dermatologist’s examination. It should not be hidden with a cosmetic treatment.

When to get it checked

Find the cause of the change.

A small sample is examined to help distinguish fungal infection from other nail conditions.
  1. 01

    Look at all the nails

    The dermatologist may examine your skin and scalp too. Explain when the change started, which nails are affected, and any injury, manicure or new product use.

  2. 02

    Test when the result will guide care

    A nail clipping or sample from beneath the nail can check for fungus. A suspicious pigment band or growth may need specialist examination and sometimes a biopsy.

  3. 03

    Review your wider health

    Bring a medicine list and mention psoriasis, diabetes, circulation problems, pregnancy or breastfeeding. Blood tests depend on the findings or planned medicine; they are not needed for every nail change.

Choose care for the cause.

A thickened nail represents a pattern that may need fungal testing.

Treat confirmed nail fungus

Selected infections may need a nail-specific topical medicine or an oral antifungal. Ordinary antifungal skin cream does not reliably treat infection inside a nail. Oral treatment needs checks for interactions and possible monitoring.

Explore fungal care
Nail pits represent one possible feature of psoriasis.

Manage nail psoriasis

Topical treatment, selected injections or wider psoriasis treatment may be considered. The number of nails affected, discomfort and any skin or joint symptoms help shape the plan.

Explore psoriasis care
Surface ridges and splitting illustrate a fragile nail.

Protect irritated or fragile nails

Reducing repeated water exposure, product irritation and trauma may help. Moisturising and practical changes at work or home can be part of care; supplements are not a substitute for finding the cause.

Inflamed skin borders the nail.

Address painful nail edges or folds

An ingrown nail, infection or persistent inflammation may need specific medicine, drainage or a nail procedure. The clinician will explain what is appropriate and arrange referral when needed.

OUR PROCEDURE

What happens at your appointment?

STEP 01

Examine the nail and surrounding skin

  • Discuss the history

    Explain pain, colour changes, lifting and everyday activities that affect the nail. If possible, attend with polish removed so the surface is visible.

  • Agree any tests

    The clinician may recommend a clipping, scraping or further examination. Ask what the test checks and how you will receive the result.

The visible parts of a nail are identified for assessment.
STEP 02

Make the next steps clear

  • Match treatment to the diagnosis

    Agree what to use, where to apply it and how long to continue. A procedure is not a routine step for every nail problem.

  • Discuss safety and practicality

    Mention other medicines and health conditions. Ask about side effects, monitoring, footwear, work and nail-product use.

A sample can inform the treatment choice.
STEP 03

Follow comfort and new nail growth

  • Give new nail time to grow

    Treatment can work before the damaged nail looks normal. Review changes at the base, discomfort and whether the problem is spreading.

  • Reassess if progress stalls

    Report new pain, colour changes or side effects. Persistent symptoms may need another test, a revised diagnosis or a different treatment.

The nail grows from the base towards its free edge.

Protect your nails between visits.

Protective gloves, moisturiser and a nail file represent gentle everyday care.
  1. 01

    Reduce repeated wet work

    Use suitable protective gloves for cleaning and wet tasks, and dry your hands afterwards. Apply a moisturiser to nails and surrounding skin if tolerated.

  2. 02

    Trim gently and avoid picking

    Keep nails manageable, avoid cutting cuticles or digging with sharp tools, and cut toenails straight across. Get help if a nail is too thick or painful to trim safely.

  3. 03

    Give toes enough room

    Avoid footwear that squeezes the toes. Treat athlete’s foot as advised, keep tools clean and do not share nail clippers when infection is suspected.

Nail improvement takes time.

The free edge is the older portion that grows out as new nail forms at the base.

Nails grow slowly. Fingernails usually replace themselves faster than toenails, and a damaged toenail can take many months to grow out. The treatment course and the time until a nail looks different are not always the same.

The goal may be healthier growth, less pain or control of infection and inflammation. Some nail damage can persist. Agree how to check progress instead of repeatedly switching products.

FAQs

Common questions

Ask us on WhatsApp
01Is a yellow nail always a fungal infection?

No. Staining, injury, psoriasis and other conditions can change nail colour. Examination and, when useful, a sample help identify the cause.

02Can a nail problem be related to psoriasis?

Yes. Pitting, lifting and thickening can occur with nail psoriasis, sometimes without obvious skin patches. Mention joint pain or stiffness too.

03Does a dark nail band always mean cancer?

No. Pigment bands have several causes, but a new or changing band should be examined promptly. Do not rely on a photograph or cover it up instead of getting it checked.

04Can I treat nail fungus with an athlete’s-foot cream?

A product designed for skin may not reach fungus in the nail. Confirm the diagnosis and ask which nail-specific treatment is appropriate.

05Will I need the nail removed?

Not usually for every nail problem. A procedure may be considered for selected painful, ingrown or damaged nails. The reason, alternatives and healing plan should be explained first.

06Should I take biotin or other supplements?

Do not assume nail changes mean a deficiency. Discuss your diet, medicines and supplements with the clinician; testing or supplementation should address a specific need.

07Can I keep using gel polish or artificial nails?

Ask first if a nail is lifting, painful or infected. Products and removal methods can irritate or damage nails, and coatings can hide changes that need monitoring.

08How quickly will the nail look normal?

That depends on the cause, the nail and its growth rate. Improvement is often measured in months, especially for toenails, and a perfect cosmetic result cannot be promised.
