Avoid using a mild shampoo; instead use an alkaline shampoo. As a hair coloring safety precaution, cosmetologists should:
A) apply hair color when a metallic hair color is present
B) use a metallic applicator bottle or bowl to mix the hair color
C) brush the hair before applying color
D) conduct a strand test for porosity, elasticity, and breakage

The best safety precaution for cosmetologists applying hair color is to conduct a strand test to check for porosity, elasticity, and breakage. This ensures the hair is in the right condition for coloring. Other options may pose safety risks or are less critical to the coloring process. ;
