This research aimed to examine the effect of the protease extracted from a Kiwi fruit(Apteryx australis) on the dyed hair, and reached the following results. In the change in the thickness of the dyed hair treated with a kiwi fruit protease, the thickness of the dyed hair began to rapidly decrease in the experimental group. Though the removal of soils was ascertained in the experimental group from one hour of the experiment through an optical microscope, significant changes were not ascertained in the control group. Also in the analysis of the proteolytic activity through Methylene blue dye methods, there were not significant changes in the experimental group by the 9th hour from the experiment and there were not significant changes in the control group. The brightness and the yellow grew lighter and the red grew decreased in the change of the surface color, and the dye amount of the dyed hair decreased according as the gap in the time and temperature grew bigger in the experimental group in the change of the dye concentration. In the observation through SEM, significant changes in the hair section were not ascertained though the soil removal and the scale scouring of the surface was ascertained in the experimental group. In the change of the tensile strength, the tensile strength grew weaker according as time went on. Accordingly, if treating the dye hair with kiwi fruit protease for about 30 minutes in the beauty treatment, it is expected to be used as an after treatment for the purpose of removing the soil of the cuticle as without increasing the hair damage.
