Which tool position will result in the least volume and the least base strength?

• A. On-Base
• B. Off-Base
• C. Underdirected
• D. Overdirected

Answer: (B)

Tool position relative to its base controls how much hair sits on the base, which in turn affects volume and base strength. When the tool sits on its base, the hair is fully supported, giving the most lift and the strongest base. Moving the tool off the base reduces contact, so the curl rises less and the base strength weakens. Directing the tool’s angle (underdirected or overdirected) changes the direction and shape of the curl, but these terms describe angle, not how much base contact you have. Therefore, positioning the tool completely off the base yields the least volume and the least base strength.
