Hair Porosity: The Thirst Is Real.

Now I know that some of you are coming across this term for the very first time and it might sound like something that is complex but its really something simple. As I mentioned in my previous post, hair porosity is your hair’s ability to absorb and hold moisture. With moisture playing a huge role in healthy hair, knowing your hair’s porosity will help in using the right oils to ensure that your hair is well moisturized.

There are three types of hair porosity:


Low porosity hair = tight cuticles which means that getting moisture in is not easy however once moisture is absorbed its pretty much not going anywhere. Due to the tight cuticles it also means that low porosity hair does not easily absorb oils therefore you would want to make use of light oils such as avocado oil, grapeseed oil, jojoba oil and argan oil.


Medium porosity hair holds a more loose cuticle which allows for the right amount of moisture be absorbed and the right amount to leave. This type of porosity has no issues in terms of absorbing and retaining moisture. The best oils for this hair type include: jojoba oil, avocado oil and coconut oil.


High porosity hair absorbs moisture easily and loses moisture just as easy due to the gaps in the cuticle. The large gaps in the cuticle can be a result of damage from heat styling, chemical processing etc. In order to lock moisture into your high porosity hair, use of much heavier oils such as jamaican black castor oil, coconut oil, olive oil and butters are key.


I determined the porosity of my hair by doing the float test. Basically what you do is take a couple of strands of hair after washing (you want your strands to be product free) and place into a glass of water for a couple of minutes.

  1. if the strands float at the top it means you have low porosity hair.
  2. strands that sink to the middle mean you have medium porosity hair.
  3. strands that pull the titanic and sink to the bottom mean you have high porosity hair.
