Seborrheic Dermatitis is a common skin condition that causes red, flaky patches, often with yellowish scales. It typically appears on oily areas of the body, such as the scalp, face, and chest. This condition can affect people of all ages, but it is most prevalent in infants (often called cradle cap) and adults. Factors like stress, weather changes, and certain medical conditions can worsen the symptoms. The exact cause of Seborrheic Dermatitis is not fully understood, but it is believed to be linked to an overgrowth of a yeast called Malassezia that lives on the skin. Treatment options include medicated shampoos, creams, and lifestyle changes to help manage flare-ups and reduce discomfort.
