A method to change the color of hair. The method includes measuring an initial reflectance spectrum [Fig 1a (10)] of a sample of the hair and analyzing a contribution of a plurality of 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 (12) having a sampling port (14) and an inner surface (16) and a window disposed (18) near the sampling port. The window is configured for being placed in close contact with the sample. The system also includes a light source (20) configured to project light onto the sample via the window and a light detector (22) configured to analyze light reflected from the inner surface (16) to produce the reflectance spectrum of the sample.
