Understanding Hair Porosity
Hair porosity refers to how well your hair absorbs and retains moisture, determined by the state of the cuticle layer. Low porosity hair has tightly closed cuticles that resist moisture penetration. Medium porosity hair absorbs and retains moisture well. High porosity hair has raised or damaged cuticles that absorb moisture quickly but lose it just as fast. Knowing your porosity helps you choose the right products and techniques for healthy, moisturized hair.
