To determine hair density

To assess scalp health

To evaluate the hair's ability to absorb and retain moisture

The main function of a porosity test in hair care is to evaluate the hair's ability to absorb and retain moisture. This test helps determine how well the hair cuticles are closed or opened, which directly affects moisture retention. Hair that is highly porous tends to absorb moisture quickly but loses it just as fast, which can lead to dryness and damage. Conversely, low porosity hair may struggle to absorb moisture but retains it effectively once it is inside the hair shaft.

Factors like chemical treatments, heat styling, and environmental exposure can alter a hair's porosity, making this test an essential tool for barbers and stylists when selecting appropriate products and treatments for their clients. Understanding the porosity of hair allows professionals to provide tailored advice, ensuring optimal hair health and maintaining proper moisture balance.
