Which statement best describes the purpose of a strand test?

• A. It Predicts Color Shade
• B. It Determines How The Hair Will React To A Chemical Product
• C. It Measures Porosity
• D. It Tests Scalp Health

Answer: (B)

A strand test shows how hair will respond to a chemical product. By testing a small section under the same conditions as the full service, you can see how the hair lifts or deposits color, how evenly the result develops, and whether the strand shows signs of damage or over-processing. This helps you decide whether to proceed, adjust the formula (strength or processing time), or pause the service to protect the hair. It’s about predicting the hair’s reaction to the chemical, not directly measuring porosity or testing scalp health.
