Why dandruff occurs
The top layer of the skin is constantly being shed and renewed. Although this usually goes unnoticed when it occurs on most areas of the body. It may become more visible on the scalp as the hair traps the scaling skin.
Cradle cap is a form of seborrhoeic dermatitis that occurs in newborns. It results in a thick, yellow-crusted scalp lesion. Other symptoms can include:
- Splits in the skin and behind the ears
- Red facial pustules
- Stubborn nappy rash
Older children can develop thick, stubborn plaques on the scalp, measuring one to two centimeters across.
Seborrhoeic Dermatitis – Factors that can make it worse
The incidence and severity of seborrhoeic dermatitis seems to be affected by:
- Other illnesses – for example, patients with neurologic disease (especially Parkinson’s disease) or HIV may have severe seborrhoeic dermatitis.
- Emotional or physical stress.
- Genetic factors – Family History
- The season – seborrhoeic dermatitis is usually worse in winter.
Psoriasis can cause itching scalp
Psoriasis is a relatively common skin condition that affects about three per cent of the population. It is often confined to the scalp, elbows and knees. While seborrhoeic dermatitis tends to involve almost all the scalp, psoriasis often occurs in small, localised patches of redness with quite prominent thick scaling. Because psoriasis may only occur on the scalp, it can be mistaken for a severe case of dandruff. Psoriasis has a genetic link – there is often a family history of the condition. Some form of stress may trigger it.
