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

Medium Porosity Hair

Medium porosity hair is often considered the easiest porosity type to manage.

Common Signs

  • Absorbs moisture easily
  • Retains moisture well
  • Minimal buildup
  • Responds well to most products

High Porosity Hair

High porosity hair absorbs moisture quickly but loses it just as fast.

Common Signs

  • Gets wet quickly
  • Dries quickly
  • Frizzes easily
  • Often feels dry
  • Requires frequent moisturizing

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.

Frequently Asked Questions

Can porosity change?

Yes. Heat, coloring, chemical treatments, and damage can change hair porosity over time.

What is the best porosity type?

There is no best porosity type. Each one simply requires a different routine.

Can 4C hair have low 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.

]]> What is Hair Porosity? – When we are talking about hair porosity, it refers to the hair’s ability to absorb moisture. Depending on the condition of your hair, your cuticle layers could be very open allowing a lot of moisture to enter. On the opposite side of the spectrum, your hair’s cuticle layers could be very tight and preventing moisture to then penetrate it. High porosity means your hair is very porous and allows a lot of moisture in. Low porosity means that your hair is less porous and resistant to moisture.

Conducting a float test is quick and easy to help determine which category your hair fits. 

Hair porosity float test: 🧜🏽‍♀️🦄

1• Fill a glass or bowl with room temperature water.

2• Take a couple strands of your clean hair (from your comb or brush) and put them in the water. *Clean hair is important. If you have oils or products on your hair, it will alter your results.

3• Watch it for 2-4 minutes.

What is hair porosity

If your hair strands stay afloat, this means that you have low porosity. Your hair is resistant to moisture. This doesn’t mean that your hair is unhealthy; it means that you need to help your hair retain moisture. Try using light hair products with humectants. Also wash and condition with warm water & deep condition with dryers. 

If your hair strands sunk in the water, then your hair is highly porous. It easily absorbs moisture and is mostly likely prone to frizz. Try adding some protein rich products to your hair regimen, such as avocado as a deep condition. Porous hair needs protein to fill in the gaps. Try using  hair products with proteins such as aloe and wheat protein.
