What is dandruff

Common cosmetic dermatological affection, more frequent in men, dandruff is manifested by scaling of the scalp ranging from a mild and periodic form to an intense and continuous one, up to manifestations that represent a real psychosocial discomfort for those it is affected: the "scales" (furfuraceous scales) fall from the hair (in man also from the beard) on the clothes, making themselves particularly evident on dark clothes and creating considerable discomfort and, often, generating an erroneous feeling of poor personal hygiene .

Too often considered a disease of oily hair to be resolved with the use of special shampoos (often of overrated effectiveness, sometimes even unsuitable), dandruff should be considered rather a sign of a dermatological disorder, in particular of an eczematous dermatitis and more precisely of seborrheic dermatitis, the most frequent cause.

In the latter case, the scales of dandruff, scientifically defined pityriasis simplex capillitii, are yellowish-white, oily, adhering to the scalp and the hair shaft, and are accompanied by an excessive production of sebum by the sebaceous glands, which gives the hair and the underlying skin its characteristic oily appearance.

Dandruff, on the other hand, can also appear in subjects with constitutionally dry skin, for example in people suffering from atopic dermatitis (the second most frequent cause of dandruff).

In this case the condition is more correctly defined pityriasis sicca and is clinically manifested by a whitish, finer and more volatile peeling, less adherent to the skin and hair, localized exclusively on the scalp, which represents the clinical expression of an increase in the turnover cell secondary to chronic inflammation typical of atopic dermatitis and is accompanied by itching.

A further cause of dandruff can be represented by psoriasis: in this case the scales are often more similar to those present in seborrheic dermatitis (therefore we speak of sebum-psoriasis, a clinical entity still little known and difficult to define) or in dermatitis atopic.

The distinction between the forms of dandruff is extremely important for framing and therefore choosing the type of treatment: in fact, the cleansing products and medicated lotions to be applied in the case of "oily" dandruff are ineffective or even contraindicated in the case of "dry" dandruff, and are likely to aggravate the flaking already present.
