Seborrhoeic dermatitis

Seborrhoeic dermatitis is essentially a more intense or extreme form of dandruff.

It’s a skin disorder that affects areas of the body where sebum – the natural oil produced by your skin cells – is produced, including:

• the scalp
• face
• upper torso

It’s caused by the same factors that cause dandruff, responding with more extreme symptoms of flaky, itchy or redskin.

Scalp psoriasis
Psoriasis is a quite rare genetic condition causing dry, scaly skin that affects just 3% of people around theworld.

The areas affected by psoriasis can include:

  • elbows

  • knees

  • navel

  • palms

  • groin

  • scalp

  • face

  • upper torso

Psoriasis has a genetic link and tends to run in families – about 30% of people with a close relative who has psoriasis develop the condition.
