A cosmetologist is preparing to perform a virgin lightener application on a client who desires to go from a natural level 6 (light brown) to a level 9 (very light blonde). To ensure even lift and prevent 'hot roots', where should the lightener be applied first?
- AThe scalp area (first 1/2 inch of new growth).
- BThe mid-shaft, 1/2 inch away from the scalp and up to the ends.
- CThe ends of the hair, then gradually working up to the scalp.
- DThe darkest parts of the hair, regardless of location.
Show answer & explanationAnswer & explanation
Correct answer: B. The mid-shaft, 1/2 inch away from the scalp and up to the ends.
In a virgin lightener application, the mid-shaft is applied first because it is typically the most resistant to lightening. The scalp area processes faster due to body heat, and the ends may be more porous, requiring less processing time.
Why the other options are wrong
- A. Applying to the scalp first would result in 'hot roots' due to faster processing from body heat.
- C. While ends can be porous, applying to ends first and then working up to the scalp would still cause 'hot roots' and potentially over-process the ends.
- D. The darkest parts are typically the mid-shaft in virgin hair, but the location relative to the scalp is key for evenness.
Virgin Lightener Application Strategy
For a virgin lightener application, the product should be applied first to the mid-shaft (1/2 inch away from the scalp up to the ends) to allow for sufficient processing time, as the scalp processes faster and ends may be more porous.
- Scalp processes faster due to body heat
- Mid-shaft is often most resistant
- Ends may be more porous or previously lightened
- Allows for even lift from roots to ends
- Prevents 'hot roots' and over-processing
Memory trick: Mid-shaft is 'M' for 'Most' resistant, so start there.
