Guidelines

Advise parents / carers:
  • It does not affect the baby
  • Tend to resolve spontaneously by ~8 months
 

1st line: massage a topical emollient onto the scalp to loosen scales → remove with infant brush / fine tooth comb → wash off with a suitable shampoo

3rd line: consider short course (up to 2 weeks) of mild topical steroid (e.g. hydrocortisone 1%) 

 

Note that topical ketoconazole is not licensed in children, therefore topical imidazole is used.

1st line: conservative care

  • Bath the infant everyday with an emollient as a soap substitute

  • Advise that it is a chronic condition, long-term maintenance treatment maybe needed
  • Use gentle soap-free wash on the skin and affected areas, apply light moisturiser after washing
  • If the patient wears make-up → use products that do not block the pores and are non-comedogenic
  • Fruit consumption may reduce flares
  • Stress may exacerbate and lead to flares

1st line: ketoconazole 2% shampoo (twice a week for up to 4 weeks, then once every 1-2 weeks for maintenance)
  • Scales can be removed by applying salicylic acid for several hours before applying shampoo
  • Shampoo should be left on for 5 minutes before rinsing off

2nd line: OTC medicated shampoos (e.g. zinc pyrithione, coal tar, salicylic acid)

3rd line: consider short course (up to 2 weeks) of topical steroid
