California Cosmetology Written ExamClient Consultation and AnalysisEasy
A cosmetologist is analyzing a new client's hair and wants to determine the number of hairs per square inch on the scalp. Which hair analysis factor is being assessed?
- AElasticity
- BTexture
- CDensity
- DPorosity
Show answer & explanationAnswer & explanation
Correct answer: C. Density
Density refers to the number of individual hair strands per square inch of scalp, typically classified as thin, medium, or thick. This is different from texture, which refers to the diameter of the hair strand.
Why the other options are wrong
- A. Elasticity measures the hair's ability to stretch and return, not strand count.
- B. Texture refers to the diameter or coarseness of individual strands, not overall count.
- D. Porosity measures the hair's ability to absorb moisture, not strand count.
Hair Density
The number of individual hairs per square inch of scalp, classified as thin, medium, or thick.
- Average density is about 2,200 hairs per square inch
- Classified as thin, medium, or thick
- Affects how much product and volume a style can hold
Memory trick: DEPT: Density, Elasticity, Porosity, Texture — check the DEPT before you chemically treat.
