FAQ about seborrhoeic dermatitis

What is the difference between seborrhoeic dermatitis and dandruff?

Seborrhoeic dermatitis is often a more severe condition, characterised by red plaques and greasy scales, whereas dandruff is generally milder and dry.

What are the triggering factors for seborrhoeic dermatitis?

Stress, a cold dry climate, genetics or even excessive sebum production can lead to the colonisation of the skin by yeasts Malassezia and trigger seborrhoeic dermatitis.

Is seborrhoeic dermatitis contagious?

No, seborrhoeic dermatitis is not contagious. It is often linked to internal factors, such as sebum production and the presence of yeasts on the skin.

Can seborrhoeic dermatitis affect the eyebrows and the sides of the nose?

Indeed, these sebaceous gland–rich areas are frequently affected by seborrhoeic dermatitis.

Can seborrhoeic dermatitis cause hair loss?
