Texas Class A Barber Written ExamAnatomy and PhysiologyEasy
A client is concerned about a sudden change in hair texture, noting it has become much coarser and more brittle. As a barber, you understand that the primary factor determining the hair's natural texture, and thus its susceptibility to such changes, is the:
- Aoverall health of the client's scalp.
- Bfrequency of shampooing and conditioning.
- Cshape of the hair follicle.
- Damount of melanin in the cortex.
Show answer & explanationAnswer & explanation
Correct answer: C. shape of the hair follicle.
The shape of the hair follicle directly influences the cross-sectional shape of the hair strand, which, in turn, determines its texture (straight, wavy, curly). Oval follicles produce wavy hair, while round follicles produce straight hair.
Why the other options are wrong
- A. Scalp health can affect hair growth and overall condition, but not the inherent texture determined by the follicle shape.
- B. While shampooing and conditioning affect hair condition, they do not determine its fundamental natural texture.
- D. Melanin content determines hair color, not its texture.
Hair Follicle Shape & Texture
The shape of the hair follicle determines the cross-sectional shape of the hair shaft, which is the primary determinant of hair texture (straight, wavy, curly).
- Round follicles produce straight hair.
- Oval follicles produce wavy hair.
- Flat/elliptical follicles produce curly/kinky hair.
Memory trick: Follicle's form shapes the hair's feel, from straight to reel.
