Understanding Hair Porosity: A Complete Guide for Curly Hair

Understanding Hair Porosity: A Complete Guide for Curly Hair


Your ultimate resource for learning how hair porosity affects your curls – and how to care for them the right way!


What is Hair Porosity?

Hair porosity refers to your hair’s ability to absorb and retain moisture. It plays a crucial role in how well your curls respond to products, hydration, and styling techniques. Understanding your hair’s porosity level can help you create a more effective curly hair routine tailored to your specific needs.


The Three Types of Hair Porosity

1. Low Porosity Hair

Cuticles are tightly closed, making it difficult for moisture to penetrate.

Water tends to bead up on the hair rather than being absorbed.

Products often sit on the hair rather than being absorbed.

How to Care for Low Porosity Hair:

Use lightweight, water-based products to prevent buildup.

Incorporate heat (like steam or warm towels) when deep conditioning to open the cuticles.

Avoid heavy butters and oils that can weigh hair down.

2. Medium (Normal) Porosity Hair

Cuticles are slightly open, allowing for balanced moisture absorption and retention.

Hair holds styles well and requires minimal maintenance.

Curls look defined and healthy with regular care.

How to Care for Medium Porosity Hair:

Maintain a balanced routine with hydration and protein treatments.

Use leave-in conditioners and lightweight styling creams for optimal definition.

Avoid excessive heat styling to prevent damage.

3. High Porosity Hair

Cuticles are widely open, allowing moisture to enter easily but escape just as quickly.

Hair can feel dry and frizzy, prone to breakage and tangling.

Often a result of chemical treatments or excessive heat styling.

How to Care for High Porosity Hair:

Use thicker creams and oils to lock in moisture.

Opt for protein-rich treatments to strengthen the cuticle structure.

Seal moisture with heavier butters or styling gels to reduce frizz.


How to Determine Your Hair Porosity


The Water Test

1. Fill a glass with water.

2. Take a clean strand of shed hair and place it in the water.

If it floats → Low porosity.

If it sinks slowly → Medium porosity.

If it sinks quickly → High porosity.


The Slip & Slide Test

Take a strand of hair and slide your fingers upward (from tip to root).

If you feel bumps or roughness, you likely have high porosity hair.

If your hair feels smooth, you may have low or medium porosity.
