Which item is NOT among the hair characteristics assessed in the pre-perm analysis?

• A. Color
• B. Porosity
• C. Elasticity
• D. Texture

Answer: (A)

The main idea is that the pre-perm analysis zeroes in on how the hair’s physical properties will react to chemical processing. Porosity tells you how easily the cuticle takes in solutions, guiding how long and how strong the perm should be. Elasticity indicates how far the hair can stretch before breaking, signaling whether the hair is strong enough for the process or needs gentler treatments. Texture describes the hair’s diameter and feel, which affects wrap pattern and product decisions. Color isn’t a hair property used to gauge how the hair will behave chemically during a perm, so it isn’t part of the assessment.
