The purpose of this study is to present the optimal dyeing time for each material through scientific experiments on the premise that the dyeing and dyeing amounts are different by dyeing time even for natural dyes of the same color material. For this purpose, the dyeing and dyeing amount of the hair surface were measured by the dyeing time of each dyeing material using five materials of yellow white, gardenia, turmeric, lump and marigold, which are used as representative yellow-based natural dyeing materials. K / S (surface dyeing concentration; dyeing amount) and L *, a *, b * values at the maximum absorption wavelength were measured.
