Seborrhoeic dermatitis is caused by the same factors as dandruff.
As your scalp produces natural oils called sebum, the naturally-occurring microbe Malassezia globosa breaks it down into an irritant,oleic acid.
This irritant causes the rate of skin cell turnover to increase dramatically, leading to large clumps of cells building up on thesurface of the scalp.
