What is the purpose of a test curl during perm service planning?

• A. To measure head size
• B. To gauge curl formation, processing time, and final texture
• C. To test shampoo fragrance
• D. To determine lighting needs

Answer: (B)

The purpose of a test curl during perm service planning is to preview how the hair will respond to the perm process. By curling a small section on the planned rod size and applying the perm solution, you can gauge how the curls will form, how long processing should take, and what the final texture will feel like. This early check lets you adjust rod size, processing time, and neutralizing approach before treating the entire head, helping ensure the result matches the client’s goals and reduces the risk of over- or under-processing. Head size, fragrance testing, or lighting needs don’t influence the curl outcome, so they aren’t relevant to planning a perm.
