Definition: Seborrhoeic Dermatitis is a chronic skin disorder characterized by an inflammation of the skin which causes a red, scaly, itchy and flaking rash. It most often occurs on the scalp, sides and corners of the nose, eyelids, behind the ears and middle of the chest. It can also occur on the belly button, underarms, breasts and genital area. When it occurs on the scalp of infants, it is called "cradle cap." When it occurs on the scalp of adults, it is often referred to as "dandruff." [Note: Dandruff usually limitis itself the scalp and does not have the redness that occurs with seborrhoeic dermatitis.] When seborrhoeic dermatitis occurs on the eyelids, it is called seborrheic blepharitis.
Caution: One of the problems with seborrheic dermatitis of the scalp, or dandruff, is that it can build up a short-term resistance to an ingredient based shampoo (mentioned above) within a few months. To prevent this from happening, one can try rotating a main ingredient shampoo after the completion of each bottle. For instance, you may start with a selenium based Head & Shoulders, and when finished with the bottle rotate to a Zinc based Selsun Blue, and then onto an anti-fungal based shampoo.
Excessive use of steroid based creams may cause the skin to become thinner.
