Highly porous hair is a type of hair characterized by its porosity, or the ability to absorb moisture. It has an open cuticle layer that allows it to absorb more moisture than other types of hair. Additionally, high porosity hair is often dry and brittle due to constant exposure to humidity, sunlight, and other environmental factors. The strands can easily become tangled and prone to breakage if not cared for properly. Common characteristics of high porosity hair include being difficult to manage, prone to frizzing, and having low elasticity. Additionally, this type of hair tends to lose its natural oils quickly, resulting in dryness if it’s not properly moisturized. To combat these issues, it's important for those with high porous hair to use specific products formulated for their particular needs such as deep conditioners and leave-in treatments.
