ʷ Abstract: In this study, we investigated the effects of oxidative permanent hair coloring agents on the dyeability and the damage of human hair. p-phenylenediamine and toluene-2.5-diamine sulfate were used as a hair coloring agent precursers. The degree of dyeability was checked by the change of CIELAB L* value according to dyeing time. And the damage of hair was evaluated by the tensile strength and morphological change of hair in SEM. When the hair was dyed, the CIELAB L* value was decreased with dyeing time regardless of the type of precursers. But when the hair was dyed after nutritional treatment, the CIELAB L* value showed lower level. This means that the nutritional treatment covers the scale of hair and protects the hair from the chemicals.
Ű Keywords: p-phenylenediamine, toluene-2,5-diamine sulfate, CIELAB L* value, hair damage, tensile strength, SEM
