Question

question 16 of 100
which of the following is true about hair porosity?
select the correct response:
hair porosity is the same all over a person’s head.
high porosity is often caused by overprocessing.
hair with average porosity requires less alkaline solutions.
hair with high porosity has a healthy cuticle.

Explanation:

• Hair porosity can vary across a person's head, so the first option is false.
• Overprocessing (like chemical treatments, heat damage) lifts the hair cuticle, leading to high porosity, making this option true.
• Low porosity hair, not average, typically needs less alkaline solutions, so the third option is false.
• High porosity hair has a damaged, raised cuticle, not a healthy one, so the fourth option is false.

Answer:

High porosity is often caused by overprocessing.
