The discovery of their hair porosity type has prompted a complete change in some people’s hair care habits, including the abandonment of beloved items for porosity-approved alternatives.

It’s been a game-changer for those with Black natural hair, or curly hair. It has further demystified a saturated hair industry and tailored products to the texture/curl pattern of one’s hair determined by the natural hair scale—which classifies the texture/curl pattern of your hair by number (1A-4C) — AND their porosity. I spoke with experts in haircare about the significance of porosity in achieving healthy “rigid-where?” curls, and whether it matters more than the natural hair scale for afro hairstyles.
