Which test is used during a virgin thio relaxer to assess progression toward the desired relaxation level?

• A. Comb test
• B. Strand test
• C. pH test
• D. Visual inspection

Answer: (A)

The test used during a virgin thio relaxer to gauge progression toward the desired relaxation level is the comb test. As the relaxer processes, the curl pattern loosens and the hair becomes easier to slide a comb through. By testing a section with a wide-tooth comb and noting how smoothly it passes, you get real-time feedback on how close you are to the target texture. When the comb moves through with minimal resistance, that’s a practical signal to stop processing, helping avoid over-processing and potential damage. This method provides immediate, texture-based feedback that aligns with the goal of reaching a specific level of relaxation.

A strand test looks at a single strand’s reaction to the chemical, which is useful for predicting overall processing but doesn’t continuously reflect progress during the service. A pH test measures the chemical’s strength rather than the hair’s texture, and visual inspection alone can be subjective and may not accurately indicate how much relaxation has occurred.
