The Problem
Porosity has become shorthand for everything.
Dry?
“High porosity.”
Product sitting on hair?
“Low porosity.”
Breakage?
“Must be porosity.”
Textured hair has been reduced to a single label — and expected to behave
accordingly.
But porosity is not a personality.
And it is not a diagnosis.
When porosity is misunderstood, routines become rigid, products become excessive,
and results remain inconsistent.
The Myth
Porosity is fixed.
This is the most damaging assumption.
While porosity has a genetic baseline, it is also highly influenced by behaviour:
Heat exposure
Chemical processing
Styling tension
Mechanical stress
Environmental wear
Hair can shift between porosity states along the same strand — roots behaving
differently than ends.
A single label cannot explain that complexity.
The Science
Porosity describes how easily water enters and exits the hair strand.
It is governed by the cuticle — microscopic scales that open and close in response
to:
pH
moisture balance
damage
friction
Low porosity hair has a compact cuticle.
Water enters slowly — but stays longer when properly introduced.
High porosity hair has a lifted or compromised cuticle.
Water enters easily — but escapes just as fast.
Neither is “better.”
They simply require different strategies.
Where Most Advice Goes Wrong
Generic porosity advice focuses on products, not conditions.
Low porosity routines often overload hair with heavy layers.
High porosity routines often chase protein without addressing hydration loss.
In both cases, the result is the same:
Hair that feels unpredictable, brittle, or dull.
Porosity does not work alone.
It interacts with:
Bond integrity
Elasticity
Styling stress
Scalp health
Ignoring these factors leads to misdiagnosis.
Why Curlévo Doesn’t Rely on Porosity Alone
FroScan® measures porosity — but it never stops there.
It contextualizes porosity alongside:
Hydration levels
Elasticity
Bond integrity
Scalp stress
Styling patterns
Because high porosity with strong bonds behaves differently than high porosity with
compromised structure.
And low porosity hair under tension behaves differently than low porosity hair left
undisturbed.
Find Out How Your Porosity Is Actually Behaving
Rather than following rules built for someone else’s hair, Curlévo uses FroScan® to
translate porosity into actionable care.
Your results determine:
Whether hydration needs to increase
Whether repair should lead
Whether sealing should be lighter or more intentional

Our Philosophy
Porosity is not a flaw.
It is a response.
When you understand the response,
you can change the outcome.
