KETOBEST SHAMPOO
KETACONAZOLE 1% SHAMPOO
KETOBEST SHAMPOO is a medicated shampoo containing ketoconazole 1%, an antifungal. It is used for dandruff and seborrhoeic dermatitis of the scalp, and as maintenance treatment to prevent recurrence, at the lower strength suited to regular use.
01
Benefits
- Ketoconazole targets Malassezia, the yeast that drives dandruff and seborrhoeic dermatitis — treating the cause rather than just removing scale.
- The 1% strength is suited to regular or maintenance use, where the 2% strength is used for active treatment.
- Reduces the itching, flaking and redness of seborrhoeic dermatitis.
- Regular use prevents the recurrence that follows stopping treatment, which is the usual pattern in this condition.
- A wash-off preparation is easily incorporated into normal hair washing.

03
Precautions
- For external use on the scalp only. Avoid the eyes; rinse thoroughly with water if contact occurs.
- Leave the lather on the scalp for three to five minutes before rinsing — rinsing immediately gives too little contact time to work.
- Contraindicated in known hypersensitivity to ketoconazole or other azole antifungals.
- Seborrhoeic dermatitis is controlled rather than cured; maintenance use is usually needed to prevent relapse.
- May affect the colour of chemically treated, permed or grey hair.
- Do not use on broken or badly inflamed scalp skin without advice.
- Seek review if there is no improvement after four weeks, or if the scalp becomes weeping, crusted or painful.
