What is a characteristic of hair with high porosity?

Hair with high porosity has a characteristic that allows it to easily absorb moisture and products. This occurs because the cuticle layer of the hair is raised or damaged, creating gaps and spaces between the cuticle scales. As a result, products can penetrate the hair shaft more readily. This trait can be beneficial for achieving moisture, as high-porosity hair readily absorbs conditioners and treatments, but it also means the hair can lose moisture just as quickly, leading to potential dryness.

In contrast, hair that is smooth and shiny typically has low porosity, where the cuticles are tightly packed and lay flat. A strong curl pattern is often associated with other factors and does not solely correlate to porosity. Resilient and strong hair generally indicates low porosity as well, where the hair structure is intact and resistant to damage. Understanding these traits helps in selecting appropriate hair care products and treatments tailored to specific hair types.
