It's important to know your hair porosity before buying products and using them on your hair. Hair porosity has little to do with hair texture. Hair porosity is determined by your hair's ability to accept and retain moisture. Hair porosity is also determined by your hair's need for protein treatments vs needing to avoid protein in hair products. Using products that aren't suitable for your hair porosity will cause hair breakage, tangles, and frizz. Do the hair test below to discover your hair porosity and it will help you choose the right products for your hair care routine.
