MEDICATION DETAILS

Description

Ketoconazole 2% w/w Shampoo

Ketoconazole 2% Shampoo is a medicated shampoo used for fungal conditions of the scalp, including dandruff and seborrhoeic dermatitis. It reduces the itching, flaking and inflammation that come with them. It is a medicine that requires a clinician to assess whether it is suitable for you.

How it works

Dandruff and seborrhoeic dermatitis are linked to Malassezia, a yeast that lives on everyone's skin but which some scalps react to. Ketoconazole is an antifungal that inhibits the growth of that yeast, and as its numbers fall the flaking, redness and itch settle. Because it treats the cause rather than just washing flakes away, it works differently from a cosmetic anti dandruff shampoo.

How to use it

Wet the hair, apply the shampoo to the scalp rather than just the hair, and leave it in contact for the time stated on the pack, usually a few minutes, before rinsing. Contact time is what makes the difference, so rinsing it off immediately wastes the treatment. Use it at the frequency directed during a flare, then less often to keep it under control, since these conditions tend to recur.

Who it is for

It is for adults and children as stated, where a clinician has confirmed it is appropriate. It is not suitable for anyone sensitive to ketoconazole, and it should be kept away from the eyes.

Safety and when to get advice

Scalp irritation, dryness and a change in hair texture are occasionally reported. See a clinician if the scalp is weeping, crusted or painful, if there are patches of hair loss, if the rash spreads to the face or body, or if there is no improvement after the course stated. Our UK pharmacy team can answer questions about this product before you buy.

Common questions

How long do I leave it on?
For the contact time stated on the pack. That is what lets it work.

Can I use my normal shampoo too?
Yes, on other days. Use the medicated shampoo at the frequency directed.

Will the dandruff come back?
These conditions tend to recur, which is why occasional maintenance use is usually advised.

Always read the patient information leaflet supplied with the pack before use.

Directions

Wet the hair and scalp thoroughly with water. Apply a small amount of Ketoconazole shampoo directly to the affected area (scalp). Gently massage the shampoo into the scalp to create a lather. Leave the shampoo on the scalp for 3-5 minutes to allow it to work. Rinse the shampoo thoroughly with water. Use as directed by a healthcare provider. Typically, it may be recommended to use the shampoo 2-3 times a week for treatment, and less frequently for maintenance.

FAQs

Please read our FAQs page to find out more.

How often should I use it for dandruff treatment versus keeping it under control?

For treating active dandruff or seborrhoeic dermatitis of the scalp, the usual recommendation is twice a week for two to four weeks. Once it is under control, using it once every one to two weeks can help prevent it coming back.

Can I use it on my body as well as my scalp?

Yes. Ketoconazole 2% shampoo can also be used on the body for pityriasis versicolor (a fungal skin condition that causes patches of discoloured skin). The usual approach is to apply it to the affected area, leave it for a few minutes, then rinse. Check the leaflet or ask our pharmacy team for the specific regimen.

Could it affect chemically treated or coloured hair?

In rare cases, people with chemically treated or grey hair have noticed a slight change in hair colour or texture. If you are concerned, test on a small area first or ask our pharmacy team at info@rightangled.com.

How long before I see an improvement?

Most people notice flaking and itching improve within two to four weeks of regular use. If there is no improvement after a full course, speak to a clinician as the cause of your symptoms may need re-assessing.
