Curl pattern tells you what your hair looks like. Porosity tells you how it behaves. Most of our curl care is formulated for medium-to-high porosities, and the Bamboo FlexiStrong Styling Jelly works at every one of them. Find yours below.
Cuticles lay flat against the hair shaft, repelling moisture and resisting absorption.
You probably have low porosity if:
EMPHASIZE: panthenol, water-soluble quats
MINIMIZE: Hydrolyzed proteins, heavy butters + oils
Cuticles open enough to deposit and retain ingredients, closed enough to hold what they take in.
You probably have medium porosity if:
EMPHASIZE / MINIMIZE: you'll probably handle most products pretty well, just make sure you're applying the right amount for your strand width + hair density.
Cuticles are raised or damaged, absorbing moisture quickly but losing it just as fast.
You probably have high porosity if:
EMPHASIZE: hydrolyzed proteins, oils + butters as part of a water-based formula, cationic surfactants
MINIMIZE: high-glycerin formulas without oils or butters to "seal" in hydration (especially in very dry or very humid air).
It's all over the internet, but it's not a real diagnostic - individual hair buoyancy depends on residue and oils, not cuticle structure. The bullets above will tell you more than a glass of water can.
