When hair breaks easily, it has what level of porosity?

When hair breaks easily, it indicates a high level of porosity. Porosity refers to the hair's ability to absorb moisture, and high porosity means that the hair cuticle is raised or damaged, allowing moisture to enter and escape easily. This condition can make hair more susceptible to damage from chemical treatments, heat styling, and environmental factors.

In contrast, hair with low porosity tends to have a tightly sealed cuticle, which makes it resistant to absorbing moisture. Medium porosity hair typically has a balance between the two extremes, allowing for some moisture retention and ease of styling. Normal porosity hair has well-functioning cuticles, providing a good balance of moisture retention and flexibility. Recognizing and understanding these different levels of porosity is crucial for selecting the right hair care products and treatments that can help manage the specific needs of the hair.
