Dandruff treatment focuses on reducing scalp yeast and calming inflammation. Antifungal shampoos (such as ketoconazole or selenium sulphide) target the underlying cause, while medicated scalp treatments and topical corticosteroids help relieve itching, redness, and flaking.
Used regularly, these treatments can control symptoms quickly and help prevent dandruff from returning.
Dandruff affects up to 50% of the population. It affects the scalp causing itchiness and shedding of white flakes. Dandruff is not contagious or infectious, however, it can be unpleasant and make people feel embarrassed. We have quick and effective treatment options for dandruff.
Our clinicians may recommend one of the treatment options below, depending on your symptoms, medical history, and whether the treatment is appropriate for you.

Speak to a clinician if your symptoms are persistent, worsening, or affecting your quality of life.
Fact: Dandruff is caused by Malassezia overgrowth and scalp inflammation — not by infrequent washing. Very frequent washing with harsh shampoos can actually irritate the scalp and worsen symptoms.
Fact: While dry scalp can cause flaking, true dandruff involves fungal activity and inflammation. The two have different appearances, causes, and treatments. Moisturising the scalp does not treat fungal-driven dandruff.
Fact: Dandruff is a chronic condition that can recur after treatment. Maintenance use of medicated shampoo (once weekly or fortnightly) is often needed to prevent it returning.
Fact: Dandruff does not directly cause permanent hair loss. Severe inflammation may temporarily weaken follicles, and excessive scratching can cause some breakage, but these effects are reversible with treatment.
Fact: Coconut oil and tea tree oil have modest antifungal properties but are not proven treatments for moderate or severe dandruff. They may help mild flaking but should not replace evidence-based antifungal shampoos for established dandruff.
Alongside medicated shampoos, these self-care steps can help control dandruff and reduce flare-ups.
Apply to a wet scalp, work into a lather, and leave for 3–5 minutes before rinsing. This contact time is critical for antifungal effectiveness — don't rush it.
Wash hair every 1–2 days during active dandruff to remove oil and fungal build-up. Once controlled, maintain with medicated shampoo once or twice weekly.
Strong detergent shampoos, heat styling, and chemical treatments can strip the scalp and worsen irritation. Use gentle, fragrance-free products between medicated washes.
Stress is a well-established dandruff trigger. Regular exercise, adequate sleep, and relaxation techniques can reduce flare frequency.
Reduce sugar and refined carbohydrates, which may promote Malassezia growth. Ensure adequate intake of zinc (pumpkin seeds, beef) and B vitamins (eggs, wholegrains), which support scalp health.
Cold weather and dry indoor heating worsen dandruff. Wearing a hat in cold weather and using a humidifier indoors can reduce scalp dryness.

The best dandruff treatment is an antifungal shampoo such as ketoconazole, selenium sulphide, or zinc pyrithione. These work by reducing the yeast that causes dandruff. For more severe symptoms, topical corticosteroids may be used to reduce inflammation, redness, and itching.
Dandruff treatment usually starts working within 1 to 2 weeks. Antifungal shampoos help reduce flaking and itching during this time, but full improvement may take up to 4 weeks with regular use.
Use dandruff shampoo 2 to 3 times a week when starting treatment. Leave it on the scalp for 3 to 5 minutes before rinsing. Once symptoms improve, reduce use to once weekly to maintain control.
Dandruff may not go away if treatment is not used regularly or is not strong enough. Persistent dandruff may require a stronger antifungal shampoo, such as ketoconazole 2%, or additional treatment with a topical corticosteroid.
Many dandruff treatments are available over the counter in the UK, including antifungal shampoos. Stronger treatments, such as higher-strength ketoconazole or topical corticosteroids, may require a prescription.
Dandruff does not directly cause hair loss, but inflammation and scratching can lead to temporary hair shedding. Treating dandruff effectively usually allows hair growth to return to normal.
You should see a doctor if dandruff is severe, not improving after 4 weeks of treatment, or spreading beyond the scalp. More persistent cases may need prescription treatment.
