Diphencyprone - Dosage and How to Use

How should Diphencyprone be used?

  • The first visit involves a sensitisation procedure, whereby a high concentration of DCP will be applied to a small patch of hair loss on the scalp and left on for 24 hours. Thereafter, DCP should be removed by wiping area with tissue before washing it in the shower. Area where DCP was applied may become itchy or blister. However, it will go away in 2-3 weeks.
  • Your child will be assessed 1-2 weeks later to decide if DCP will work. If an eczematous reaction (ie. area becomes red and itchy) is present, your child can be started on DCP.
  • DCP is applied usually once a week and continued until hair is regrown. It comes in different concentrations and may be slowly increased over time.
  • It is recommended to leave DCP on the affected area for 24 hours. However, if reaction is intolerable (severe itching, burning or blistering), DCP may be washed off after a minimum of 4 hours. The aim is to achieve tolerable itch for 24 to 48 hours.
  • It is advisable to shield head with a cap or cloth to protect from sunlight after application. This is to prevent DCP from getting degraded by sunlight. Care should be taken to avoid DCP touching other areas.

Treatment is recommended to be continued for at least 6 months. If no response is seen after 6 to 12 months, it may be recommended to stop treatment. Your child will require multiple trips.
