Porosity is your hair’s ability to hold and maintain moisture as is defined by three levels: low, medium, and high.
Low porosity hair means the cuticles are sealed down, making it very hard for moisture to come in. Medium porosity means the hair is able to receive and retain the right amount of moisture into the hair cuticle. High porosity means the cuticles are torn, creating pores along the hair strand which allows moisture in, but it does not retain the moisture.
