| ABSTRACT |
|
The purpose of this research is to find out how hair color turns when the bleaching agent 1 made of different concentration of sodium metasilicate is put on the hair. Specifically, we measured color-difference meter with spectrophotometer. The result is as follows. As the higher the concentration of sodium metasilicate is, the higher L* which shows brightness becomes. Also B* which shows color spectrum between yellow and blue has a tendency to be similar with L*. It is advisable to make sodium metasilicate with high concentration of 15% (S3) to get the vivid bleaching effect. It is recommendable to make sodium metasilicate with high concentration of 20% (S4) to get better bleaching effect than standard reagent (S). In conclusion, concentration of sodium metasilicate is a significant factor determining the degree of the bleaching agent.
