Hair that readily absorbs moisture due to open cuticle layers is described as which porosity?

• A. Low porosity
• B. Medium porosity
• C. High porosity
• D. No porosity

Answer: (C)

Moisture moves into and out of hair most easily when the cuticle layers are raised or damaged. That open-cuticle condition lets water and styling products pass through quickly, which is what we call high porosity. This means the hair soaks up moisture readily but can also lose moisture quickly, often drying faster and sometimes frizzing more easily. By contrast, hair with tightly closed cuticles resists absorption (low porosity) and takes longer to wet, while a balanced, in-between condition is medium porosity.
