Understanding Hair Porosity: Which Botanical Oils Suit Your Strands?

What is Hair Porosity?

Hair porosity refers to your hair shaft’s ability to absorb and retain moisture. It is determined by the condition and arrangement of your cuticle scales—the overlapping protective shingle layers along each strand.

Understanding your porosity changes everything about how your hair accepts botanical oils.

Matching Oils to Your Porosity Type

Low Porosity: Your cuticle scales lie flat and tight. Heavy oils sit on the surface. Opt for lightweight liquid wax esters like Golden Jojoba and Argan that slip effortlessly into microscopic spaces.

High Porosity: Your cuticles are raised or weathered from heat/chemical processing. Water escapes rapidly. You need sealing lipids rich in ricinoleic and lauric acids like Jamaican Black Castor and Virgin Coconut Oil.
