What is Seborrheic Dermatitis?
Seborrheic dermatitis is the most common form of dermatitis on the scalp. This rash affects mainly adults, however, in some cases it can also occur in childhood. Seborrheic dermatitis of the scalp is a disorder of the maturation and desquamation of the stratum corneum and should be considered as a true minor skin pathological condition.
What are the causes of seborrheic dermatitis?
The causes of seborrheic dermatitis vary from person to person, but are mainly linked to:
- genetic predisposition
- environmental factors (stress and seasonality)
What does seborrheic dermatitis look like?
Seborrheic dermatitis looks different depending on where it appears
- on the scalp: dandruff or small scaling plaques
- on the hairline: redness and scaling
Dandruff as a symptom can often mean seborrheic dermatitis is misdiagnosed as simply that. However, dandruff – the flaking of the scalp into small white lamellae – is often caused by external factors such as:
- Use of harsh shampoo
- Inadequate rinsing
- Over-washing
- Scratching the scalp during washing
- Hair cosmetics (lotions, rubs)
- Hair salon treatments (dying, styling, etc.)
- Excessive hot air drying
In these cases it is sufficient to remove the causes and the dandruff disappears.
Seborrheic Dermatitis, on the other hand, worsens if subjected to the external factors mentioned above and, unlike simple Dandruff, does not heal by eliminating it.
Seborrheic Dermatitis is noticed by the presence of Dandruff on the hair or clothes, i.e. silvery flakes that have detached from the scalp.
Usually, but not necessarily, the subject feels itchy and is driven to scratch.
In bald subjects and in the most severe forms, adherent plaques composed of yellowish scales can be seen. In addition to scaling with silver or yellowish gray lamellae, Seborrheic Dermatitis is characterized by scalp redness and itching.
