Dandruff - Pityriasis Simplex Capitis (PSC) Syn. P. Sicca
'Dandruff' is a popular (non-specific non-technical) collective name signifying a scaly flaking scalp condition.
In a simple context this will allude to Pityriasis Simplex Capitis (syn. pityriasis sicca) a non-inflammatory scalp condition which presents as exfoliation of the Stratum Corneum (outer layer of epidermal cells) due to the presence of Pityrosporon Ovale. Pruritis may co-exist. It is common to both sexes and shows no affiliation to race or skin colour.
Human skin continually manufactures and sheds cells. Clothing often assists in the shedding. Hairy skin may contain these exfoliated cells which articulate to form scales.
PSC may be an indication of a more serious condition.
