After unwinding the perm rod 1.5 times, what is assessed to gauge curl formation?

• A. Test curl
• B. Color check
• C. Texture assessment
• D. Smell test

Answer: (A)

Gauging curl formation by performing a test curl after unwinding the perm rod partway. Unwinding the rod 1.5 times lets you see the actual shape the hair is taking around the rod, which reveals how tight or loose the curl will be and whether it’s forming evenly. This direct observation guides whether to continue processing, adjust timing, or proceed to neutralizing. Other checks don’t reveal curl pattern: color checks assess pigment changes, texture assessment looks at hair feel rather than curl shape, and a smell test isn’t related to curl development.
