PSI Barbering Practice Exam

Hair with a high porosity level indicates that the hair cuticles are raised or damaged, allowing moisture to enter and exit the hair shaft more easily. This condition is often the result of previous over-processing, such as excessive coloring, perming, or chemical treatments. These processes can weaken the cuticle layer, leading to increased porosity. When the cuticle is compromised, hair becomes more susceptible to moisture loss, making it prone to dryness and breakage. High porosity hair often requires additional care, such as the use of deep conditioning treatments and products that help to seal in moisture, countering the effects of past damage. This understanding is crucial in choosing the right hair care regimen for clients with similar porosity levels, as it directly influences the health and appearance of their hair.
