Understanding Hair Porosity: Why It Matters for Your Hair Care Routine

When it comes to choosing the right hair products or building a routine that actually works, there’s one crucial factor that’s often overlooked: hair porosity. Whether you're trying to maintain colour, boost hydration, or strengthen strands, understanding your hair’s porosity level can transform the way you care for it—and help you achieve healthier, more manageable hair.

In this guide, we’ll break down what hair porosity means, how to identify your porosity type, and why it’s the key to unlocking the best results from your hair care products.

What Is Hair Porosity?

Hair porosity refers to your hair’s ability to absorb and retain moisture. It’s determined by the condition of the cuticle—the outer layer of your hair strand. The more open or raised the cuticle is, the more porous your hair will be.

Porosity is generally grouped into three categories:

• Low Porosity
  
• Medium (Normal) Porosity
  
• High Porosity
  

Each type behaves differently when it comes to product absorption, moisture retention, and response to styling or colouring.

Why Hair Porosity Matters

Understanding your hair’s porosity allows you to:

• Choose the right hair products (think oils, treatments, conditioners)
  
• Improve moisture retention
  
• Minimise breakage and dryness
  
• Extend the life of your hair colour
  
• Achieve more consistent styling results
  

Without this knowledge, you might be using expensive products that simply don’t work—because they’re not suited to your hair’s unique needs.

How to Test Your Hair Porosity

The Float Test:

1. Take a few clean, dry strands of your hair.
   
2. Drop them into a glass of water.
   
3. Wait 2–4 minutes.
   

Results:

• Floats: Low porosity
  
• Hovers mid-glass: Medium porosity
  
• Sinks quickly: High porosity
  

Simple, quick, and surprisingly accurate!

Low Porosity Hair: The Resistant Type

Cuticle Status: Tightly closed
Moisture: Hard to absorb, slow to dry
Common Traits: Product build-up, water beads on surface, resistant to chemical treatments

Care Tips:

• Use lightweight, water-based products
  
• Avoid heavy butters and oils that sit on top of hair
  
• Apply heat when deep conditioning to help open the cuticle
  
• Opt for clarifying shampoos to remove product build-up
  

Recommended Products: Lightweight leave-ins, clarifying shampoos, protein-free moisturisers

Medium Porosity Hair: The Balanced Type

Cuticle Status: Slightly open, even structure
Moisture: Absorbs and retains moisture well
Common Traits: Easy to style, holds colour well, low maintenance

Care Tips:

• Stick with a balanced routine (moisture + protein)
  
• Use regular conditioners and deep treatments weekly
  
• Protect your hair from heat and environmental damage
  

Recommended Products: Moisturising masks, gentle shampoos, moderate protein treatments

High Porosity Hair: The Thirsty Type

Cuticle Status: Raised or damaged
Moisture: Absorbs quickly, loses moisture fast
Common Traits: Frizz-prone, easily tangled, breakage, quick colour fade

Care Tips:

• Focus on sealing in moisture with heavier creams or oils
  
• Use protein-rich treatments to strengthen cuticle
  
• Minimise heat styling and avoid harsh chemicals
  
• Rinse with cold water to help seal the cuticle
  

Recommended Products: Protein masks, sealing oils, hydrating conditioners

Why Porosity Is Essential for Colour-Treated Hair

If you colour your hair—especially with permanent or lightening treatments—knowing your porosity level becomes even more important. High porosity hair tends to fade colour faster, while low porosity hair may resist dye altogether. Tailoring your products and application method based on porosity will give you richer colour and better longevity.
