What is porosity?
Porosity refers to the hair's ability to absorb and retain water. It depends on the condition of the cuticles.
The water glass test
Place a clean hair on a glass of water: if it floats, low porosity. If it stays in the middle, medium. If it sinks, high.
Care by porosity type
Low
Light proteins, gentle heat to open cuticles, avoid heavy oils.

Balanced hydration/protein routine.
