Hair Porosity

Have you ever heard the term “hair porosity” and wondered what it meant? Basically, this term refers to hair’s ability to absorb and retain moisture.

It’s important for us naturalistas to understand how porous their hair is, so we can figure out how our hair responds to products.

Subhead: How Can I Figure Out My Hair Porosity? 

Figuring out your hair’s porosity is pretty easy! 

First, fill a glass with water, and then grab two strands of your hair and drop them into the glass. 

If your hair sinks to the bottom of the glass, your hair is highly porous. If it floats in the middle of the cup, it has a medium porosity. And if it floats at the top, your hair has a low porosity.

Subhead: Does Hair Porosity Even Matter? 


Knowing your hair porosity can help you boost your understanding of your hair overall, and helps you make sense of the way your hair reacts to your products. Figuring out your hair porosity can help you understand why your hair gets dry sometimes, why it feels weighed down by certain products, and why other products make your hair look and feel amazing.


Subhead: What Each Hair Porosity Means and How to Care for It

Now that you’ve figured out your hair porosity, it’s time to learn what it means and how to properly care for it.

  • High porosity—Hair with a high porosity has raised cuticles, which makes it easy for moisture to move in and out quickly. This type of hair usually looks frizzy and straw-like without proper care. 

Let highly porous hair dry naturally as much as possible to keep from zapping all of the moisture out of it. Heat keeps the hair’s cuticles raised, so finish up each wash day with a cold water rinse to help seal in moisture and smooth the cuticles down.

  • Medium porosity—Hair with a medium porosity strikes the perfect balance between high and low porosity. This type of hair can hold moisture in for a long time, and it easily absorbs products.

Medium porosity hair is pretty easy to care for. Make sure to keep up your deep-conditioning routine to keep your hair moisturized and healthy.

  • Low porosity—Hair with a low porosity has tightly-closed cuticles, which makes it harder for moisture and products to absorb into the hair. Products tend to sit on top of low porosity hair, making it look weighed down and causing buildup.

Avoid using too much product in low porosity hair, and apply products to hair while it’s slightly damp to help them sink into the hair. Use a clarifying shampoo as needed to remove any product buildup.
