When it comes to the care and keeping of hair—especially natural hair—there's far more to be concerned with than simply finding the right shampoo and conditioner. Great haircare is also about crafting a personalized routine that fosters scalp health, hydrated strands, and consistent hair growth. And in finding this routine, it's helpful to know about the needs of your hair and scalp, including whether your hair is low porosity or high porosity.
"Porosity is the ability of the hair to absorb liquid," explains Alicia Bailey, a licensed master cosmetologist and the CEO and Global Hair Education Director of Iman Yvonne Beauty. "Hair that has low porosity has a tight cuticle layer, which makes it slightly harder to absorb water, products, and various chemicals."
