What is seborrhoeic dermatitis?

Seborrhoeic dermatitis is a common chronic inflammatory disorder that affects mainly young adults in areas that are rich in sebaceous glands e.g. scalp, face, chest, underarms and back. It can range from mild red patches on the skin with dandruff to severe redness and yellow scaling over multiple body areas. In infants, it is better known as ‘Cradle cap’.  It is presents as yellowish scaly patch on the scalp, but mostly resolves on its own within a few months.

What causes seborrhoeic dermatitis?

The exact cause of seborrhoeic dermatitis is unknown but multiple factors such as  stress, hormones, fungal colonisation, genetics, and environmental triggers may be involved. Here are some of the factors that may contribute or increase the risk of getting seborrhoeic dermatitis

  • Environmental triggers: low temperatures, changes in humidity.
  • Stress 
  • Sleep deprivation
  • Fungal colonisation by the Malassaezia species
  • Increased sebum production: The condition is seen in adolescence and young adults, affecting males more than females. 
  • Immunosuppresion: Seborrhoeic dermatitis is more commonly associated with a weakened immune system such as HIV
  • Neurological disorders such as Parkinson’s disease may put an individual at higher risk.
  • Psychiatric conditions such as depression and mood disorders may increase risk of seborrhoeic dermatitis.

how is seborrhoeic dermatitis diagnosed?

The diagnosis of seborrhoeic dermatitis is based on a clinical history and examination. Some skin disorders such as atopic eczema, psoriasis and fungal infections may resemble seborrhoeic dermatitis and should be differentiated from one another .

how do you treat seborrhoeic dermatitis?

The treatment of seborrhoeic dermatitis depends on your age,  severity of the condition and also the areas affected. As the nature of seborrhoeic dermatitis is frequently relapsing, good skin care with a maintenance regime is necessary to reduce symptoms and improve quality of life.

In addition to reducing the amount of fungi on the skin, anti-fungal creams have an anti-inflammatory effect. They reduce redness, itch and can be used for treatment of flares and maintenance.  Common anti-fungals include:

  • Ketoconazole
  • Ciclopirox
  • Sertaconazole

Intermittent use of a mild steroid can be helpful to bring down an acute flare of seborrhoeic deramtitis. However, as steroids are associated with side effects such as skin thinning, visible blood vessels and the appearance of shiny skin, their use is limited to short term use only.

Calcineurin inhibitors act by reducing the inflammatory component of seborrhoeic dermatitis. From studies, they have found to reduce redness, scaling and itchiness compared to baseline. They are considered safer to use on sensitive areas such as the face compared to steroids due to its steroid-sparing side effects. 

  • Pimecrolimus
  • Tacrolimus

For severe or cases not responding to topical therapy, oral anti-fungal therapy is effective at reducing inflammatory symptoms such as redness, scaling and itchiness.

  • Itraconazole
  • Terbinafine
