Seborrheic dermatitis refers to a chronic inflammatory skin condition that affects regions of the body that are rich in sebaceous (oil) glands, most commonly the scalp, face, and chest. It is characterized by the presence of red, scaly patches or plaques on these areas, accompanied by itchiness and flaking.
This condition is believed to result from an interplay of genetic, environmental, and hormonal factors. While the exact cause is unclear, it is thought to involve an overgrowth of a yeast called Malassezia, which normally resides on the skin. However, in individuals with seborrheic dermatitis, the presence of this yeast triggers an immune response, leading to inflammation and the resulting symptoms.
Seborrheic dermatitis commonly occurs in infants (cradle cap) and adults (dandruff), with symptoms typically waxing and waning over time. Although it is a chronic condition, it is not contagious.
Treatment options for seborrheic dermatitis involve both medical and self-care measures. These may include the use of over-the-counter or prescription-strength antifungal creams, corticosteroids, or medicated shampoos. In addition, a gentle skin care routine with regular shampooing and conditioning of the affected areas, avoiding harsh soaps or irritants, and maintaining good hygiene practices can help manage the condition. Regular follow-up with a dermatologist may be necessary to assess response to treatment and adjust therapy if needed.
In summary, seborrheic dermatitis is a chronic inflammatory skin condition characterized by red, scaly patches on areas rich in oil glands. It is believed to result from an interaction between genetic, environmental, and hormonal factors. While not curable, it can be effectively managed with
