Hair porosity refers to the hair's ability to absorb and retain moisture. This characteristic is influenced by the condition of the hair cuticle, which is the outermost layer. Porous hair has gaps and holes in the cuticle layer that allow moisture to be absorbed more easily, but it can also lead to moisture escaping quickly.

Understanding porosity is essential for choosing the right hair care products and treatments. High-porosity hair tends to absorb moisture readily but may struggle to retain it, hence requiring heavier conditioning treatments to maintain hydration. Conversely, low-porosity hair is less porous, which means it resists moisture absorption but can retain it well once it has been absorbed.

The other options relate to other properties of hair but do not accurately define porosity. Color pertains to the dye retention capabilities of the hair, heat relates to how hair can withstand thermal styling, and style refers to the hair's ability to hold a particular shape or form after styling products or techniques are used. Thus, moisture is the correct element associated with porosity.
