Flesch (18) has suggested the use of an acid rinse after bleaching the hair to reduce the injurious chemical changes. His presentation at a recent scientific meeting of the Toilet Goods Association was very provocative. In this presentation I have attempted to discuss the etiological factors in the production of seborrhea capiris. The various methods of approach have been described. Individual selections must be made according to the desired dermatological effect. A wide variety of chemical agents are being utilized in the treatment of seborrhea capiris and their advantages and disadvantages have been enumerated. With increase in the number of hair cosmetics and hair treatments, there are bound to be some damaging effects produced, particularly when the cosmetics are used injudiciously or unintelligently. The possible inclusion of corticosteroids and other anti- inflammatory agents in cosmetic preparations should be explored.
