Symptoms vary slightly depending on the area (s) affected:

• On the scalp (most common): white scales, kinds of dandruff visible on clothes or shoulders when the person combs their hair, red scalp, itching.
• On the skin, these are red patches that peel. They are preferably located:
  • On the face : in the nasolabial folds (grooves between the nose and the two ends of the mouth), the wings of the nose, the eyebrows, the eyelids, behind the ears, and in the external auditory canal. The plaques generally form symmetrically.
  • On the trunk, the back : on a median vertical line between the breasts (intermammary zone), or on the back a median zone between the shoulders (interscapular zone).
  • On genital areas, hairy areas and folds, for example, groin folds.

• Itching: they are relatively frequent, but not systematic and can be accompanied by burning sensations.
• The lesions are very inconstant: they come and go, often triggered by stress, fatigue or overwork. And they are enhanced by the sun.
