Seborrheic dermatitis on scalp

What are the main causes of seborrheic dermatitis?

The seborrheic dermatitis is a very common, non-contagious skin condition which is also known as a type of eczema or skin inflammation. It can develop regardless of age and affects every 5th person.

The oily skin parts, mostly the scalp, facial skin or chest are more prone to be affected. The symptoms include dandruff-like white to yellowish scales and greasy or purulent skin parts. Redness and itching are also typical and may be accompanied by increased hair loss.

The inflammatory mechanism of seborrheic dermatitis causes the shortening and fastening of tissue regeneration process. This eventuates an enhanced, constant abrasion of the superficial stratum corneum and dandruff.

The development mostly depends on hereditary factors. The seborrheic skin type comes with an abundant production of sebum and along with familial occurrence these are considered as high risk factors of the conditions. Studies have found an association of Malassezia species (a genus of lipophilic fungi) with dandruff because of its increased micro inflammatory and irritative effect.

Hormonal imbalance, obesity, stress reaction, poor diet changes, alcohol consumption, and improper skin care routine are also typical predisposing factors of this skin condition.

The seborrhoeic inflammation cannot be cured completely. The tendency persists after treating the symptoms because the seborrheic skin type is not a one-time status but a basic characteristic feature of some people. There are asymptomatic periods but exacerbations occur every now and then. Fortunately with proper care it can be kept under control but for prevention it’s important to avoid the risk-factors too.
