Question

All of the following are determined by a strand test in a color service except:

a) Processing time
b) Final color result
c) Hair texture
d) Porosity level

Answer 1

In a color service, a strand test helps determine processing time, final color result, and porosity level, but not hair texture, which is a genetic trait.

Step-by-step explanation:

In a color service, a strand test is performed to determine several key factors such as the processing time, final color result, and the porosity level of the hair. However, the one aspect that is not determined by a strand test in a color service is c) Hair texture. Hair texture is a genetically controlled characteristic that includes the curl pattern, thickness, and consistency of the hair and is not influenced by the application of hair color.
