What’s your hair’s porosity?
Hair Porosity is defined as the ability to absorb and maintain moisture in the hair.
Low Porosity hair can have difficulties getting moisture into the hair. People with low porosity may use steam + warm water to open cuticles so moisture can be absorbed into the hair while the cuticles are open.
High Porosity hair can have difficulties maintaining the moisture in hair. People with high porosity hair may seal their cuticles by rinsing their hair in cool or cold water or blow drying on the cool setting. (sealing high porosity hair with a sealant is extremely important)
