California Cosmetology Written ExamHair RemovalHard
A cosmetologist is threading a client's eyebrows using the traditional twisted-cotton-thread method. Which part of the technique is directly responsible for catching and lifting the hair out of the follicle?
- AThe straight, untwisted section of thread
- BThe technician's fingers pressing down on the skin
- CThe twisted portion of the thread rolling across the skin
- DThe tension created by holding the thread ends taut
Show answer & explanationAnswer & explanation
Correct answer: C. The twisted portion of the thread rolling across the skin
In threading, a doubled strand of cotton thread is twisted and rolled quickly across the skin's surface; the twisted section catches multiple hairs in its coils and plucks them out from the follicle in a single motion.
Why the other options are wrong
- A. The straight section of thread does not have the coiling action needed to trap hair.
- B. Finger pressure stabilizes the skin but does not remove the hair itself.
- D. Tension keeps the thread taut and controlled but is not what physically traps the hair.
Threading Technique
A hair removal method using a twisted cotton thread rolled across the skin; the twist of the thread traps and pulls hairs out at the follicle level.
- No chemicals or heat involved
- Twisted coils of thread trap multiple hairs at once
- Commonly used for eyebrows and facial hair, precise shaping
Memory trick: Twist traps — the coiled thread is the tiny lasso for hair.
