What does the term “porosity” refer to in hair properties?

• A. The strength of the hair
• B. The hair's ability to absorb moisture
• C. The thickness of the hair strand
• D. The hair's color intensity

Answer: (B)

Porosity in hair refers to the hair's ability to absorb moisture. This property is crucial for hairstyling and treatment processes, as it determines how well the hair can take in moisture, conditioners, and color products. Hair with high porosity can quickly absorb moisture due to its cuticle layer being raised or damaged, making it more susceptible to frizz and breakage, while low porosity hair has a tightly sealed cuticle that makes absorption more difficult. Understanding porosity helps cosmetologists choose appropriate products and techniques to maintain hair health and achieve the desired results.
