The ability of hair to absorb moisture is referred to as hair porosity. This characteristic is crucial in understanding how well hair can retain water and other products. Hair porosity is influenced by the condition of the hair cuticle, which can be tightly closed, moderately open, or widely open.

When hair has low porosity, it means that the cuticles are closely packed, making it difficult for moisture to enter. Conversely, high porosity hair has gaps and holes that allow moisture to be absorbed easily, but may also lead to moisture escaping quickly. Understanding porosity helps stylists and barbers select the appropriate hair care products and treatments for their clients, ensuring optimal hydration and health for the hair.

The other terms do not specifically relate to moisture absorption: hair density deals with the number of hair strands on the scalp, hair elasticity refers to the hair’s ability to stretch and return to its original length, and hair texture describes the thickness or fineness of individual hair strands. Each of these aspects significantly contributes to hair health and styling, but they do not define the moisture absorption capability like porosity does.
