What does "hair porosity" indicate?

Hair porosity refers to the hair's ability to absorb moisture, which is a critical aspect of hair health and maintenance. It reflects how well the hair can take in and hold onto water and other products. This ability is influenced by the condition of the hair cuticle, the outermost layer that protects the inner structure of the hair strand.

When hair has high porosity, it means the cuticles are raised or damaged, allowing moisture to enter easily but also making it difficult for the hair to retain that moisture. Conversely, low porosity hair has tightly packed cuticles, making it challenging for water and products to penetrate, often requiring extra effort to achieve moisture balance.

Understanding hair porosity is essential for selecting appropriate hair care products and treatments that align with the individual needs of the hair type, ensuring better moisturization and overall health.
