High porosity hair is characterized by its ability to absorb moisture quickly but also its tendency to dry out rapidly. This occurs because the cuticle layer, which protects the hair shaft, is raised or damaged, allowing moisture to enter easily. While this trait can be beneficial when it comes to absorption, it presents challenges by making the hair prone to losing that moisture just as quickly, resulting in a dry and brittle texture if not properly maintained.

In contrast, other characteristics mentioned, such as resistance to damage or being thick and coarse, do not accurately describe high porosity hair. This type of hair often feels fragile due to its high porosity, indicating that it requires careful handling and the right products to maintain moisture. Similarly, high porosity hair generally does not require no products but instead benefits from products that help to lock in moisture and provide protection against environmental factors.
