Question

What four factors about the hair should be considered in a hair analysis?

A) Hair texture, color, length, and elasticity
B) Porosity, density, thickness, and curl pattern
C) Scalp condition, oiliness, dryness, and pH level
D) Split ends, frizz, shine, and volume

Answer 1

In hair analysis, the four factors to consider are hair texture, color, length, and elasticity, which provide insights into its genetics, health, and physiological roles like protection and insulation.

Step-by-step explanation:

When conducting a hair analysis, the four factors that should be considered are hair texture, color, length, and elasticity. Hair texture can be determined by observing characteristics like curl pattern, thickness, and consistency, which are influenced by genetics and the composition of hair, primarily its keratin content. Hair color is dictated by the type and amount of melanin (eumelanin and/or pheomelanin) present in the hair. The length of the hair provides insights into hair growth rates and potential trimming practices, while elasticity can indicate the health and structural integrity of the hair.

Hair features serve multiple physiological roles, including thermal insulation, UV radiation protection, and the trapping of particles and microorganisms in the nasal passages. These factors contribute to the overall analysis of the hair's condition and potential treatments or care required.
