If strand test curls are looser than desired, what adjustments can be made?

• A. Use larger rods, decrease processing time, or adjust chemical strength; re-test on a new strand.
• B. Use smaller rods only.
• C. Decrease processing time.
• D. Stop the service entirely.

Answer: (B)

When strand test curls are looser than you want, the goal is to tighten them. Using smaller rods concentrates the curl around a smaller diameter, producing tighter ringlets. After switching to smaller rods, re-test on a new strand to confirm the result before continuing with the service. Using larger rods would loosen the curl further, decreasing processing time would also loosen, and stopping the service isn’t a relevant adjustment in this scenario.
