People with congenital dry skin often also have a dry scalp at the same time. The dandruff is triggered by micro-inflammatory foci of the scalp that are not firmly localised. The cause is an altered microflora / fungi or bacteria caused by a pH shift of the hydrolipid film. Tormenting itching and redness are often the result. Frequent hair washing increases the discomfort.

A very common, mainly plant-related skin disease is seborrhoeic dermatitis, which primarily affects middle-aged men. The male sex hormone androgen causes increased sebum production (even women can be affected). The skin disease manifests itself in yellowish, oily dandruff, which forms on the scalp, among other things. Seborrheic dermatitis is harmless, non-infectious and one of the most common skin diseases. For the treatment of seborrhoeic eczema, anti-fungals and cortisone preparations are considered. In addition, scalp shampoos containing octopirox, selenium disulphide and tea tree oil, which have a fungicidal and anti-scaling action (DERMASENCE Haircare Shampoo, DERMASENCE Selensiv Shampoo), provide good support for medical treatment. In most cases, the areas of skin normalise very quickly under therapy. However, the seborrheic dermatitis often occurs again after stopping the preparations or is generally chronic.

In general, neurodermatitis is a chronic, relapsing skin disease with a genetic background. The predisposition to the development of skin lesions is inherited, but the expression is dependent on a variety of factors (allergies, colonisation of the skin by bacteria, mental factors, etc.). In adult atopics, dandruff-dissolving preparations such as salicylic acid-containing oils can be used at short notice. As a support mild shampoos are used (DERMASENCE Milk Serum Shampoo).

Psoriasis vulgaris is a condition that is only in exceptional cases limited to the scalp and is sometimes difficult to distinguish from seborrhoeic dermatitis. Hairy heads show sharply defined and reddened, sometimes slightly raised plaques (accumulation of skin scales) with firmly adhering, silvery shining scales. In psoriasis, cell renewal is greatly accelerated. The treatment can be done in a variety of ways and belongs in the hands of a specialist. In addition, shampoos containing salicylic acid, selenium disulphide, ichthyol light and tea tree oil (DERMASENCE Selensiv Shampoo, DERMASENCE Medicinal Shampoo) can assist in relieving persistent plaques in the head area. The increased formation of horny cells and increased sebum flow is regulated and the colonisation of the scalp with bacteria and fungi is counteracted.
