Higher porosity in hair means that the cuticle layers are raised or damaged, which allows moisture and products to penetrate more easily. This condition facilitates better absorption of products, such as conditioners, treatments, and styling aids. The open cuticles create more space for these products to enter the hair shaft, which can be particularly beneficial for dry or chemically treated hair that needs extra moisture and nutrients.

In contrast, hair with lower porosity typically features tightly aligned cuticles that make it more challenging for products to penetrate effectively. This hair type may require specific products that help to lift the cuticles for better absorption.

Understanding hair porosity is crucial for choosing the right products and treatment regimens, as it directly influences how well hair can take in moisture and nutrients. Thus, the concept that higher porosity correlates with increased product absorption is key to effective hair care.
