Porosity
Porosity is a term hairdressers use to describe how well hair can absorb and hold moisture. Think of hair like a sponge - some hair absorbs products quickly and holds moisture well (high porosity), while other hair resists absorption (low porosity). Understanding porosity helps hairdressers choose the right products and treatments for clients' hair. This is especially important when doing chemical services like coloring, perming, or straightening, as hair with different porosity levels will react differently to these treatments.

Example Interview Questions
Senior Level Questions
Q: How do you determine the best treatment approach for different porosity levels?
Expected Answer: A senior stylist should explain their systematic approach to testing hair porosity, including float tests and observation methods, and how they adjust chemical processing times and product choices accordingly.
Q: How do you train junior stylists about porosity?
Expected Answer: Should demonstrate teaching methods for helping new stylists understand porosity concepts, including hands-on demonstrations and explaining how porosity affects different chemical services.
Mid Level Questions
Q: How does porosity affect color application?
Expected Answer: Should explain how high porosity hair absorbs color quickly and may need shorter processing times, while low porosity hair might need longer processing times or different developer strengths.
Q: What products do you recommend for different porosity levels?
Expected Answer: Should discuss specific product recommendations for high, medium, and low porosity hair, explaining why certain ingredients work better for each type.
Junior Level Questions
Q: How do you test for porosity?
Expected Answer: Should be able to describe basic porosity tests like the float test or spray bottle test, and explain what the results mean.
Q: What are the three levels of porosity?
Expected Answer: Should explain high, medium, and low porosity in simple terms and describe basic characteristics of each level.
