Porosity in relation to hair refers specifically to the hair's ability to absorb and retain moisture. This characteristic is influenced by the condition of the hair cuticle, which is the outer layer that protects the inner structure of the hair shaft. Hair with high porosity has holes or gaps in the cuticle, allowing moisture to be absorbed easily but also leading to quicker loss of moisture. Conversely, hair with low porosity has a tightly bound cuticle that resists moisture absorption, making it more challenging to keep hydrated.

Understanding porosity is crucial for selecting appropriate hair care products and treatments. For example, individuals with high porosity hair often benefit from heavier, moisturizing products, while those with low porosity hair may need lighter products that can penetrate the hair shaft more easily. This understanding helps in maintaining hair health and managing styling practices effectively.
