Understanding Low, Medium & High Porosity Hair
Related Porosity Guides
Hair porosity refers to your hair’s ability to absorb and retain moisture.
Understanding your hair porosity can help you choose the right products, build a better routine, and keep your hair healthier over time.
Quick Answer
Hair porosity describes how easily water and moisture enter and leave your hair strands.
There are three main porosity types:
- Low Porosity
- Medium Porosity
- High Porosity
Why Hair Porosity Matters
Two people can have the exact same hair type but completely different moisture needs.
For example, two people with 4C hair may need very different products depending on their porosity level.
Low Porosity Hair
Low porosity hair has tightly packed cuticles that resist moisture.
Common Signs
- Water sits on the hair
- Products remain on the surface
- Hair takes a long time to get wet
- Hair takes a long time to dry
- Buildup happens easily

Simple Hair Porosity Test
The Spray Bottle Test
- Start with clean hair
- Spray a section with water
- Watch how quickly the water absorbs
Water beads up = often low porosity.
Water absorbs normally = often medium porosity.
Water absorbs instantly = often high porosity.

Absolutely. Hair type and hair porosity are separate characteristics.
Final Thoughts
Knowing your hair porosity can help you choose better products, improve moisture retention, and build a routine that works for your specific hair needs.
