LOW POROSITY
Your cuticles are tightly sealed, making it tough for moisture to penetrate. You need lightweight, water-based products that absorb with the help of heat.
The Guarded One
medium porosity
the balanced one
Your hair is the Goldilocks of porosity. Moisture goes in and stays without drama. You thrive on consistent maintenance and balanced formulas.
HIGH POROSITY
The Thirsty One
Your cuticles are wide open. Moisture gets in fast but escapes even faster. You need rich, protein-packed products that seal hydration in for the long haul.
