Here’s the truth about this buzzword — and why you should care.

You’ve probably heard stylists or hair influencers talk about “high porosity” or “low porosity” hair…
But what does it really mean — and does it even matter?
Let’s break it down.
What is Hair Porosity?

Hair porosity = how well your hair absorbs and holds moisture.
It’s determined by the condition of your hair cuticle (the outer layer).
There are 3 types:
- Low porosity: tight cuticles, hard for moisture to enter
- Medium/normal porosity: balanced moisture flow
- High porosity: open cuticles, absorbs fast but loses fast too
Why It Matters
Because your porosity level affects:
- How your hair reacts to products
- What type of products work best
- How your hair responds to heat, humidity, and color
Ignoring porosity can lead to product build-up, dry hair, or wasted mone

| ❌ Too much heat or harsh chemicals — they worsen damage |
