Chapter 12 409 Dandruff is more than just superficial flaking, as demonstrated by significant structural changes in the stratum corneum and changes in inflammatory biomarkers. Dandruff and seborrheic dermatitis share a similar etiology based on metabolic activity of the cutaneous commensal yeast, Malassezia globosa, the presence of sebaceous lipids, and individual susceptibility. Today, dandruff can be successfully treated by multiple antifungal or topical steroidal anti-inflammatory agents. Due to the cost, poor cosmeticity, and adverse effects of steroidal agents, they should be confined to severe or refractory cases. When considering treatment options, one must consider that long-term, chronic therapy will be required, as Malassezia are commensal microbes and will return upon cessation of treatment. This necessitates that patients be highly compliant to any therapy. As hair is a significant driver of cosmetic appeal, for any subject to remain compliant to long-term therapy the treatment must be cosmetically appealing as well as effective. References 1.
