Seborrhea (or sebum) refers to an overproduction of sebum (skin oil) by the sebaceous glands of the skin. This condition is often associated with oily skin and scalp and can lead to various skin problems, including seborrheic dermatitis acne and oily hair. Seborrhea can occur in both adults and infants and varies in severity.
causes
The exact causes of seborrhea are not fully understood, but it is believed that a combination of genetic, hormonal, and environmental factors plays a role. Factors that may contribute to excessive sebum production include:
- Hormonal fluctuations : Androgens (male sex hormones), which are present in both sexes, can increase sebum production. This is why seborrhea often occurs during puberty , pregnancy, or in cases of certain hormonal disorders.
- Genetic predisposition : A familial tendency towards oily skin and hair can 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 nutrition : Stress and certain dietary habits can also influence skin oil production.
Symptoms
- Oily skin and hair : The most noticeable symptoms are an oily shine on the skin and hair that gets greasy quickly.
- 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, primarily on the scalp, face and other areas rich in sebaceous glands.
- Mild skin irritation : Some people with seborrhea also experience skin irritation or a slight burning sensation.
Treatment and management
The treatment of seborrhea aims to alleviate symptoms and control sebum production:
- Medicated shampoos : Special shampoos containing zinc pyrithione, tar, salicylic acid or ketoconazole can help in the treatment of seborrheic dermatitis of the scalp.
- Topical medications : Creams and lotions containing anti-inflammatory agents or antifungals can be applied to the skin in cases of seborrheic dermatitis.
- Gentle skincare : Mild cleansing and avoiding products that can irritate or dry out the skin are recommended.
- Nutrition and lifestyle : A healthy diet and stress management can also contribute to improving skin condition.
It is important to consult a dermatologist if symptoms persist or are severe, in order to receive a proper diagnosis and treatment. In some cases, longer-term treatment may be necessary to control seborrhea.
