The condition in which the cuticle is lifted or missing is:

The condition in which the cuticle is lifted or missing is:

• A. Low porosity
• B. Extreme porosity
• C. Normal porosity
• D. High porosity

Answer: (B)

Porosity describes how easily hair absorbs and loses moisture, and it is governed by the condition of the cuticle, the outer protective layer. When the cuticle scales are lifted or missing, the surface becomes rough and open, which is extreme porosity. This is more severe than simply having a high porosity because the protective barrier is significantly compromised, allowing substances to penetrate rapidly and moisture to escape readily. In contrast, low porosity has a tightly bound cuticle that resists absorption, and normal porosity sits in between.
