퍼머넨트 웨이브의 형태 변화에 미치는 환원제의 영향

Abstract

This study is to make pH.9 reduction by adding NaOH to 1, 3, 5, 7, 9, 11% solution of thioglycollic acid, cys-teine, cysteamin, to add it on helically winded natural hair and colored hair and leave them for 20, 40, 60 minutes, to adNaBrO3 oxidant for 15 minutes and to compare and analyze the wave form. This study showed the results of permanentcentration, and processing time, there were a little difference between thioglycollic acid and cysteine. But cysteamine notonly showed apparent difference but also formed strong and elastic wave. The permanent wave is affected by the diagono-sis of hair, the choice of permanent solution and the processing time. Therefore the scientific diagonosis of hair is to beconsidered first of all. By choosing the kind of solution, the concentration and the processing time according to the resultsof hair diagonosis and wave form, we can prevent the lengthening and damage of hair.
