Porosity.
Your hair's porosity decides what actually works on it.
Porosity is how well your hair's cuticle absorbs and holds moisture. It's not the same as hair type or texture, and it's the single biggest reason a product that works for someone else does nothing for you. Naturofolic™ is built around this - every shampoo, conditioner, and treatment is formulated for a specific porosity, not a generic "hair type."
Low Porosity
The cuticle sits tightly closed. Moisture takes longer to get in, but once it's in, it stays.
Hair often takes a while to wet or dry, and products tend to sit on top instead of absorbing.
Heavy butters and oils cause buildup here - what this hair type needs is lightweight, water-based formulas that can actually get through the cuticle.
High Porosity
The cuticle is more open, so hair absorbs moisture fast but loses it just as fast, which shows up as dryness, frizz, and tangling.
This type needs richer, moisture-sealing formulas that lock in what the hair takes in.
Medium Porosity
The cuticle is moderately open, so it absorbs moisture and nutrients well.
That's generally a good sign, but it also means this hair type shows dullness or premature greying more easily if it isn't cared for consistently.
Why It Matters More Than "Hair Type."
Two people with the same texture can have completely different porosity, and completely different needs.
That's why Naturofolic™ formulas are built porosity-first.
If you're not sure which one you are, the Hair Check walks you through it in five questions.
Common mistakes by porosity.
Low porosity - Heavy butters and oils sit on top and cause buildup. Skip thick products - use lightweight, water-based formulas that can actually get through the cuticle, and avoid over-using protein treatments which can leave hair feeling stiff.
High porosity - The biggest mistake is skipping moisture-sealing. Heat styling without a protectant and skipping conditioner both make this hair type more prone to frizz and damage. Seal every wash with a rich, moisture-locking product.
Medium porosity - Easy to neglect since this hair type looks fine on the surface. Wash regularly with a mild, pH-matched shampoo and don't skip scalp massage - it keeps circulation up and prevents dullness or premature greying from creeping in.
Common questions
about porosity.
Can hair porosity change?
Temporarily, yes. Heat styling, colouring, perming, and sun exposure can damage the cuticle and shift how your hair behaves - but it generally returns to its natural porosity over time once the damage is repaired.
Is one porosity type "better" than another?
No. Each type simply has different needs. Low porosity holds moisture well once it's in; high porosity absorbs product quickly. Neither is a flaw - they just need different care.
