Porosity refers to the hair's ability to absorb moisture, and it plays a crucial role in how hair interacts with various products and treatments. When hair has high porosity, it means the cuticles are more open, allowing moisture and products to be absorbed more readily. This can be advantageous for hydration but may also make the hair more vulnerable to damage and loss of moisture. Conversely, if hair has low porosity, the cuticles are more tightly packed, which can impede moisture absorption and require products to be applied differently to achieve effective hydration.

Texture is primarily characterized by the thickness or fineness of the hair strand rather than porosity. Elasticity is influenced by the protein structure of the hair, which is separate from porosity. Hair color is determined by pigmentation and does not correlate directly with the ability of hair to absorb moisture. Understanding porosity is fundamental for hair care, as it dictates how different types of hair will respond to various treatments, styling products, and environmental factors.
