Seborrhea (or seborrhea) refers to excessive production of sebum (skin oil) by the skin's sebaceous glands. This condition is often associated with oily skin and scalp and can lead to various skin problems including seborrheic dermatitis, acne and greasy hair. Seborrhea can occur in both adults and infants and varies in severity.


The exact causes of seborrhea are not fully understood, but a combination of genetic, hormonal and environmental factors are thought to play a role. Factors that may contribute to excessive sebum production include:

  • Hormonal fluctuations : Androgens (male sex hormones), which are found in both sexes, can increase sebum production. That's why seborrhea often occurs during puberty , pregnancy or certain hormonal disorders.
  • Genetic predisposition : A family history of oily skin and hair may increase the likelihood of seborrhea.
  • Certain medical conditions : Diseases such as Parkinson's disease and certain eating disorders may be associated with seborrhea.
  • Stress and Diet : Stress and certain dietary habits can also affect skin oil production.


  • Oily skin and hair : The most noticeable symptoms are an oily shine to the skin and hair that becomes greasy easily.
  • Acne : Excessive sebum can clog pores and contribute to the formation of acne.
  • Seborrheic dermatitis : A condition characterized by red, scaly, itchy, and inflamed areas of skin, particularly on the scalp, face, and other areas rich in sebaceous glands.
  • Mild skin irritation : Some people with seborrhea also experience skin irritation or a mild burning sensation.

Treatment and management

Treatment of seborrhea is aimed at relieving symptoms and controlling sebum production:

  • Medicated shampoos : Special shampoos containing zinc pyrithione, tar, salicylic acid, or ketoconazole can help treat seborrheic dermatitis of the scalp.
  • Topical medications : Creams and lotions containing anti-inflammatory agents or antifungal agents can be used on the skin for seborrheic dermatitis.
  • Gentle skin care : Mild cleansing and avoiding products that can irritate or dry out the skin are recommended.
  • Diet and lifestyle : A healthy diet and stress management can also help improve skin condition.

It is important to consult a dermatologist if symptoms persist or are severe for appropriate diagnosis and treatment. In some cases, longer-term treatment may be necessary to control seborrhea.
