Dandruff · Itchy scalp

Note flake appearance, oiliness and when itching occurs. These observations help you describe the problem, not diagnose it. Seek medical assessment for persistent discomfort, pain, oozing or hair loss.

Frequently Asked Questions

Common Questions, Clear Answers

Start with the essentials, then explore what they mean for your circumstances.

Do white flakes mean head lice?

No. Dandruff and nits are different. If you suspect head lice, read our related guide and ask a pharmacist.

Will a moisturising shampoo definitely stop the itching?

There is no guarantee. First consider whether dandruff, product irritation or another factor is involved. Persistent or significant discomfort needs its cause assessed.

Before choosing care

Record the appearance and location of flakes, when itching occurs, and any recent changes to hair care or styling products.

What can magnification show?

It can show flake size, oil, surface build-up and redness. Eczema, psoriasis and fungal infections need a doctor's diagnosis.

If the flakes are all white, is the care the same?

Not necessarily. Small, loose flakes may look different from larger scales that cling to the scalp or hair. Also note oiliness, tightness, itching or redness. These clues help the conversation, but flake size alone cannot diagnose dryness, seborrhoeic dermatitis or another condition.

Understand your scalp before choosing cleansing strength

If your scalp still itches after washing or feels increasingly tight, note the shampoo, how often you use it and when discomfort occurs. Avoid repeated scratching or stronger cleansing. Significant redness, swelling, pain, oozing or persistent thick scales call for medical assessment.

An itchy scalp does not always mean it needs more washing

Dandruff, product reactions and other skin conditions can all cause itching. If you recently changed shampoo, hair dye or styling products, note the timing and affected areas. Avoid repeatedly scratching with your nails.

How should I choose and use an anti-dandruff shampoo?

If dandruff keeps returning despite regular washing, ask a pharmacist about a suitable anti-dandruff or medicated shampoo. Follow that product's label for frequency, where to apply it and how long to leave it on, then rinse thoroughly. Instructions vary; do not increase frequency or contact time on your own. If it does not improve, or you also have significant redness, swelling, pain or hair loss, see a doctor.

How can everyday observation help?

Your practitioner can explain visible oil, surface build-up and appearance to guide cleansing choices. Similar-looking conditions can have different causes. Images at 50 to 200 times magnification cannot independently diagnose eczema, fungal infection or other disease.

What can I do at home?

Start with a few everyday habits

  • Wash with comfortably warm water. Very hot water is not needed for a better clean.
  • Cleanse gently with your fingertips rather than scratching hard with your nails.
  • Gently blot with a towel after washing. If using a hairdryer, choose low to medium heat, keep it moving and avoid holding it close to one area.
