What is Hair Porosity + 3 Reasons Why You Need To Know Your Hair’s Porosity

Hair Porosity

Do you know what your hair porosity is? If you don’t know anything about hair porosity, then it can be a bit confusing trying to figure out what it is. Hair porosity refers to your hair’s ability to absorb moisture. Hair porosity is broken down into three categories: low porosity, normal porosity, and high porosity. The cuticle layer of your hair is affected by your hair porosity, it determines how easily it is for moisture and oil to get into your hair. Porosity is mostly genetic, though you can also alter your hair’s porosity by exposing your hair to heat, and certain chemicals.

By knowing your hair’s porosity level, you can better assess and choose the right products that will be able to keep your hair moisturized and healthy.

Porosity Test

To find out your hair porosity you can do a simple hair porosity test. To do the hair porosity test drop a strand of hair that is clean into a glass of water. From your results, you will be able to determine your hair’s porosity level. You may find that your hair sinks to the bottom if so your hair is of high porosity. Hair that floats in the middle will be normal porosity. If your hair floats at the top of the glass, you have low porosity hair.

Low Porosity

If you have low porosity hair then you may notice that it is very hard to moisturize your hair. Low porosity hair tends to repel moisture. With low porosity hair, your hair cuticles are very tightly closed which makes it hard for water to enter your hair shaft. You may also notice that products just sit on top of your hair and have a hard time penetrating your strands. Low porosity hair may also take a long time to dry. Some ways to help with low porosity hair includes: steaming your hair to open up your cuticles. This will allow moisture into your strands. Also, use light oils like grapeseed and argan oil that won’t weigh your hair down. Low porosity hair is also prone to build up. So clarifying your hair is beneficial. I love using my Bentonite Clay Treatment.

High Porosity

If you have high porosity hair, you may notice that you can easily moisturize your hair, but you are unable to retain that moisture. High porosity hair always tends to look dry and dull, tangles easily and is frizzy. To care for your high porosity hair, it is best to use heavy butter and oils.

Normal Porosity

I don’t know many curly girls with normal porosity hair. Normal Porosity hair absorbs just the right amount of moisture and is shiny and has lots of volume.

Why It’s Important To Know Your Hair Porosity Type

  1. Knowing your porosity type will help you with growth and also help you maintain your healthy hair.
  2. It will help you be able to better select products for your hair. This will, in turn, save you time and money.
  3. When you know your hair’s porosity, it will help you keep moisture in your hair which will help you maintain healthy and manageable hair.

    I’ve been natural for too long to never have done a porosity test. I don’t know why I psyched myself into believing it’s so difficult but I really need to get my life together and find out Foxy’s needs, lol.

    I have high porosity hair. I could lean my head on the couch or headrest in my car and the entire back of my head would be dry. Doesn’t matter how much I try to keep it moisturized. I really need to look into some different products.

    I didn’t learn this until well into my natural hair journey. I’ve recently cut my hair again and am thinking about if I want to grow it out or not. This will definitely come in handy if I go back to growing it out again.

    I”m the unicorn with normal porosity hair. That was until I colored my hair, which of course made my hair more porous. Now that I’ve removed all the color treated hair, I’m loving my hair’s porosity is back to normal.

    My hair porosity has always been low. Even with introducing color to my tresses. My hair takes forever to dry but once that moisture is lock in, it is locked in for a while. Great article.
