Seborrhea is a chronic skin condition of which causes scaling, oiliness and redness of the skin, most commonly on the scalp (in which case it is often referred to as dandruff), face, and ears. Symptoms include scaly or flaky patches overlying red skin. Seborrhea and dandruff is multi-factorial, with over- colonization of yeast and excess oiliness being the main contributing factors. Although the skin behaves like it is dry, moisturizing does not help. Professionally recommended treatments such as cortisone creams and lotions and reduction of yeast on the skin surface, in combination with frequent gentle washing with the right shampoo, can alleviate symptoms.
