Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Expected to find color difference between the tested groups G1, G2 and G3, verified through the objective method using the Vita Easyshade spectrophotometer, and the subjective method using the Vita Classical and Vita Bleachedguide color scale, from the costing of a hair variation minus 3 points in the pre and post intervention analysis. | — |
Secondary
| Measure | Time frame |
