Today, we are talking about porosity because it is a subject that I have been asked to discuss several times. If you are interested in your hair and looking for an effective routine, you have certainly heard about porosity. If you have trouble having beautiful, healthy hair despite the care you give it, it may be because it is not adapted to its natural porosity. Knowing if your hair is porous or not will guide you towards the care to be given to them. Understanding your hair is essential to treat it properly! In this article, I will explain everything about hair porosity, how to evaluate it and the care to be taken based on the test result. Let’s go! Let’s go!
The porosity of the hair, kézako?
Porosity is the hair’s ability to absorb moisture. It is determined by the shape of the cuticle, composed of scales, and is defined according to the low, medium and high scale:
- On hair with low porosity, compact and closed cuticles are observed. This hair has difficulty absorbing moisture, which prevents the hair from hydrating;
- On healthy hair, slightly open cuticles are observed. They allow the hair to breathe and moisture to enter and exit, this is the average porosity;
- On hair with high porosity, the cuticles are very open. This hair absorbs water but does not retain it.
The porosity test
As you can imagine, the porosity of the hair cannot be assessed with the naked eye! There is a very simple test to find out how porous your hair is. To perform this test, you will only need a lock of hair (clean, dry and without any product on it) and a glass of water. Be sure to take a wick that has not had a conditioner, care, oil or other product recently.
Step 1: Put your wick in a glass of water filled
Step 2: Wait 2 to 3 minutes
- If your hair stays on the surface: you have low porosity
- If your hair flows slowly and stops in the middle of the glass: you have an average porosity
- If your hair ends up in the bottom of the glass: you have a high porosity
So what do I do now?
Knowing the porosity of your hair is good, but now what do we do? No panic, I give you here some tips to maintain your hair in an optimal way, according to its porosity:
- If your hair has a low porosity (hair remaining on the surface of the glass, as I do), you should feed it with light vegetable oils to avoid weighing it down. No more mango or shea butter that are too heavy, prefer oils like safflower, resin seed, jojoba (my favorite) or argan. You can do an ultra-protein treatment (provided you moisturize well the rest of the time) once every two months. I will soon do an article on the subject.
- If your hair has a medium porosity (stagnant wick in the middle of the glass), you are very lucky! They absorb and retain moisture and care according to their needs. You can moisturize your hair with applesauce for example (leaving it to work for 1 hour) then rinse with warm water. Once every two weeks, you can feed your hair with the vegetable oil of your choice (jojoba, argan, avocado…).
- If your hair has a high porosity (hair that flows quickly to the bottom of the glass), it is important to provide it with protein BEFORE making a moisturizing mask. On the nutritional side, unlike low-porosity hair, you can use rich butters and oils such as castor oil, coconut oil or karapate. You can then rinse your hair with vinegar water. Be careful not to use too hot water on your hair. Cold water will be your best ally!

I hope this article has helped you to better understand the nature of your hair. These tips are general but do not serve as a general truth. As with all other beauty tips, it is best to try several things by yourself (over a few weeks), to see what is best for your head hair;).
