Hair color measurement and treatment |
摘要 |
A method to change the color of hair. The method includes measuring an initial reflectance spectrum of a sample of the hair and analyzing a contribution of a plurality of natural hair factors to the initial reflectance spectrum. The method also includes calculating a hair treatment based on another reflectance spectrum. A system to measure a reflectance spectrum of a sample includes an integrating sphere having a sampling port and an inner surface and a window disposed near the sampling port. The window is configured for being placed in close contact with the sample. The system also includes a light source configured to project light onto the sample via the window and a light detector configured to analyze light reflected from the inner surface to produce the reflectance spectrum of the sample.
