When should a stylist perform a curl test with hot rollers?

Performing a curl test with hot rollers before applying them to a client's hair is crucial for several reasons. This test helps the stylist determine the appropriate temperature for the rollers as well as the suitability for the client's hair type. Different hair textures react differently to heat, and conducting a curl test allows the stylist to see how the hair responds. It ensures that the rollers will create the desired curl effect without causing damage to the hair.

Additionally, by testing the temperature on a small section of the hair or on another material, the stylist can assess whether the heat is too high, which could lead to burns or over-processing. It is a preventive measure that promotes the health and safety of the client's hair while also achieving the intended styling goals.
