A cosmetologist is setting pin curls and wants the tightest, most durable curl with the least amount of mobility, positioned close to the scalp. Which stem type should be used?
- AHalf stem
- BCascade stem
- CFull stem
- DNo stem
Show answer & explanationAnswer & explanation
Correct answer: D. No stem
A no-stem pin curl has the entire circle of the curl placed directly on its base with no stem extending from the base, producing the strongest, tightest curl with minimal mobility.
Why the other options are wrong
- A. Half stem gives medium curl and medium mobility.
- B. Cascade stem is not a standard pin curl stem classification.
- C. Full stem gives maximum mobility and the loosest curl, the opposite of what is needed.
Pin Curl Stem Types
The stem is the section of hair between the scalp and the first turn of the curl; stem length controls mobility and strength of the curl.
- No stem: circle placed directly on base, tightest curl, least mobility
- Half stem: circle placed half off base, medium curl and mobility
- Full stem: circle placed completely off base, loosest curl, most mobility
Memory trick: 'No stem, No move' — no stem curls stay glued to the scalp with zero mobility.
