Ketoconazole 2% shampoo, supplied as Dandrazol, is an antifungal shampoo for dandruff, seborrhoeic dermatitis and pityriasis versicolor. It works by reducing the yeast (Malassezia) on the scalp and skin that causes flaking, itching and patches. For adults, after a short online consultation.
Keep the shampoo out of your eyes. If you use a steroid cream or lotion on the same area, don’t stop it suddenly: keep using it and reduce it over 2 to 3 weeks while you start the shampoo. If your scalp or skin hasn’t improved after 4 weeks, see your GP.

Ketoconazole 2% shampoo is an antifungal medicated shampoo. We supply it as Dandrazol 2% Shampoo, which contains ketoconazole 20mg in every gram. Ketoconazole reduces Malassezia, a yeast that lives on everyone’s skin but can overgrow and cause dandruff, seborrhoeic dermatitis (red, flaky, itchy patches on the scalp, face or chest) and pityriasis versicolor (pale or darker patches on the chest, back or arms).
For dandruff and seborrhoeic dermatitis, the usual routine is twice a week for 2 to 4 weeks, then once every 1 to 2 weeks to stop it coming back. For pityriasis versicolor, it’s used once a day for up to 5 days. Each time, leave it on for 3 to 5 minutes before rinsing. If you only have dandruff and would rather not have a consultation, Nizoral Anti-Dandruff Shampoo is a pharmacy version of ketoconazole licensed for dandruff.
Dandrazol 2% Shampoo is available to adults aged 18 and over after a short online consultation, which one of our prescribers reviews before it’s dispensed. If approved before 3pm, Monday to Friday, your order is dispatched the same day in plain, discreet packaging: choose Royal Mail Tracked 48, Tracked 24 or Special Delivery guaranteed by 1pm next working day.

Ketoconazole shampoo may be suitable if you’re 18 or over and have:
dandruff that hasn’t cleared with ordinary anti-dandruff shampoos;
seborrhoeic dermatitis: red, greasy or flaky, itchy patches on the scalp, eyebrows, sides of the nose, behind the ears or on the chest;
pityriasis versicolor: pale, pink or brown patches, often on the chest, back or upper arms, that may be slightly scaly.
Don’t use it if you’re allergic to ketoconazole or any of the ingredients.
Tell us if you:
use a steroid cream, lotion or scalp application on the same area;
have very sore, broken or weeping skin, or patches that are spreading quickly;
have psoriasis, or aren’t sure what’s causing your symptoms.
See your GP instead if your scalp has thick, silvery scales (this may be psoriasis), you have hair loss in patches, or the skin is very red, hot or painful.
Yes. We supply ketoconazole 2% shampoo as Dandrazol 2% Shampoo after a short online consultation, so one of our prescribers can confirm it’s right for you before it’s dispatched.
For the Dandrazol 2% Shampoo we supply, yes. It’s licensed for seborrhoeic dermatitis and pityriasis versicolor as well as dandruff, and this version is prescription-only. Our online consultation includes the prescription, so you don’t need to see your GP. If you only have dandruff, some ketoconazole shampoos licensed just for dandruff, such as Nizoral Anti-Dandruff, are pharmacy medicines you can buy without a prescription.
Yes. Dandrazol is a brand of ketoconazole 2% shampoo; each gram contains 20mg of ketoconazole, the same as other 2% ketoconazole shampoos such as Nizoral. The Dandrazol 2% Shampoo we supply is licensed for dandruff, seborrhoeic dermatitis and pityriasis versicolor.
For dandruff and seborrhoeic dermatitis, twice a week for 2 to 4 weeks, then once every 1 to 2 weeks to stop it coming back. For pityriasis versicolor, once a day for up to 5 days. Leave it on for 3 to 5 minutes each time before rinsing.
Yes. Ketoconazole is an antifungal medicine. In shampoo form it reduces Malassezia, a yeast on the skin that can cause dandruff, seborrhoeic dermatitis and pityriasis versicolor. It’s a medicated shampoo, so use it as directed rather than as your everyday shampoo.
Most people notice less flaking and itching within 2 to 4 weeks of using it twice a week. Pityriasis versicolor patches are treated in 5 days, but the colour of your skin can take several months to even out after the yeast has gone. If your scalp hasn’t improved after 4 weeks, see your GP.
Yes. If you’ve been using a steroid cream or scalp application, don’t stop it suddenly, because your skin can flare. Keep using it alongside the shampoo and reduce it gradually over 2 to 3 weeks. Tell us about any treatments you use during your consultation.
Rarely. Hair colour changes have been reported, mostly in grey, chemically treated or damaged hair. Hair loss has also been reported rarely, although dandruff and seborrhoeic dermatitis can cause hair shedding themselves.
Wash every third day
Caution FLAMMABLE: keep away from fire or flames after you have used the medicine. FOR EXTERNAL USE ONLY. SHAKE THE BOTTLE. Spread thinly on the affected skin only.
