A cosmetologist places end papers around each strand of hair before wrapping it onto a perm rod. What is the primary purpose of the end papers?
- ATo increase the size of the resulting curl
- BTo neutralize the odor of the perm solution
- CTo speed up the chemical processing time
- DTo keep the ends smooth and controlled, preventing fishhooks and uneven curl
Show answer & explanationAnswer & explanation
Correct answer: D. To keep the ends smooth and controlled, preventing fishhooks and uneven curl
End papers (end wraps) hold the fragile, porous ends of the hair smoothly against the rod so they wrap evenly and process at the same rate as the rest of the strand, preventing bent or fishhooked ends.
Why the other options are wrong
- A. Curl size is determined by rod diameter, not end papers.
- B. End papers have no deodorizing function.
- C. Processing time is controlled by chemistry and heat, not paper.
End Papers (End Wraps)
Thin, porous papers wrapped around hair ends before rodding to keep ends smooth and evenly saturated during a perm.
- Prevent fishhooks (bent, distorted ends)
- Help distribute solution evenly to porous ends
- Common types: single and double wrap methods
Memory trick: Paper wraps the tips so no fishhooks slip.
