In hair care, what does the term “porosity” specifically refer to?

Porosity in hair care specifically refers to the hair's ability to absorb and retain moisture. This characteristic is crucial for understanding how hair interacts with moisture, oils, and various hair care products. Hair porosity can be classified into three categories: low, medium, and high.

Low porosity hair has tightly packed cuticles that make it challenging for moisture to penetrate, often resulting in product buildup. Medium porosity hair has a looser cuticle structure that allows for balanced moisture absorption and retention, making it generally easier to manage. High porosity hair, on the other hand, has gaps and holes in the cuticle, leading to a quick absorption of moisture but also a tendency to lose it just as fast.

Understanding porosity helps individuals choose the right types of products and routines that cater specifically to their hair's needs, ultimately promoting healthier hair and improved moisture retention. This knowledge is essential for selecting the right moisture treatments, conditioners, and styling products that will work effectively based on the hair's porosity level.
