Porosity in hair care is specifically related to the hair's ability to absorb moisture and product. It refers to the condition of the cuticle layer of the hair, which can vary in how tightly or loosely the scales are packed. When hair has high porosity, the cuticle scales are more raised or damaged, allowing moisture and products to penetrate easily. Conversely, low porosity hair has tightly sealed cuticles, making it more challenging for moisture and products to be absorbed. Understanding porosity is crucial for selecting appropriate hair care products and treatments, as it informs how well the hair can retain moisture and how it reacts to different products.

Other concepts such as the thickness of the hair strand, the natural color of the hair, and the shine and luster are separate characteristics and do not relate to porosity. These aspects are important in hair care but do not affect the hair's ability to absorb moisture or product, which is the primary definition of porosity.
