Question: 1 / 400

What does the term "porosity" refer to in hair?

The density of the hair strands

The hair's ability to absorb moisture

Porosity in hair refers specifically to the hair's ability to absorb moisture. This characteristic is determined by the condition of the cuticle, which is the outermost layer of the hair shaft. If the cuticle is tightly packed and smooth, the hair is considered low porosity and is less likely to absorb moisture or products. Conversely, if the cuticle is raised or damaged, the hair exhibits high porosity, allowing it to take in moisture quickly but also increasing the risk of moisture loss. Understanding porosity is essential for choosing the right hair care products and treatments, as it affects how the hair responds to moisture and how well it retains it. This concept is crucial for hairstylists and cosmetologists when advising clients on the best hair care practices tailored to their specific hair types.
