What does the term 'porosity' refer to in hair care?

The term 'porosity' in hair care specifically refers to the hair's ability to absorb moisture. This characteristic is crucial for understanding how hair interacts with different products and treatments. Hair with high porosity absorbs moisture easily but may struggle to retain it, often leading to dryness and frizz. On the other hand, low porosity hair is more resistant to moisture absorption, which can make it challenging to hydrate and may require specific techniques to ensure proper moisturizing.

Understanding porosity helps stylists tailor their hair care regimen to meet individual needs, ensuring the right moisture balance is maintained. This aspect is essential in developing strategies for styling, conditioning, and treating hair, as it directly impacts the effectiveness of various products and techniques used in hair care.
