The three say, what, why and how

What is the porosity of the hair?

The porosity of the hair is your hair's ability to absorb moisture. Low porosity means that your hair has a hard time absorbing the moisture, while a high porosity means your hair absorbs a lot of moisture, but also the hair strand quickly closes the moisture out again.

Why is it important to me?

It is important that you know the porosity of your hair, as this will allow you to get the most out of your products and their nourishing ingredients. This is because depending on the porosity your hair has, you have to apply the products to your hair in different ways. At low porosity, use heat at high porosity cold water. 

How can I test my hair? And how do I treat my hair?

In order not to repeat ourselves too much, we have gathered the answers to these in the boxes below. Good reading 😉

What are the three types of porosity and what should I be aware of?

Low porosity

Low porosity means that the hairs are closed. This means that moisture has difficulty pulling into the hair. Conversely, once it has come in, it is difficult to get out of the hair.

The hair can easily be weighed down and feels greasy, using too many moisturizing and nourishing ingredients. Since products with heavy ingredients cannot penetrate the hair.

What should I be aware of?

Use heat to open the hairs when applying care products. Therefore, it is a good idea to wrap a warm towel around your head when wearing a hair mask.

Look after coconut oil, babassu oil, palm oil, and other small-molecule oils or butter and which are dominated by saturated fatty acids. As these can penetrate the hair.

Medium porosity

Medium (normal) porosity hair will typically have features of both low and high porosity because its condition is between heavy, low porosity and dry and damaged high porosity hair.

It's easy to style and relatively smooth, shiny at the roots, but crumpled, glossy and dry at the tips. You may also find that the hair becomes greasy or dry by using the wrong products.

What should I be aware of?

You're lucky you just have to do as you normally do. Your hair needs neither extra heat nor anything else.

Look after macadamia oil, argan oil, jojoba oil, sesame oil, avocado oil, camellia oil, moringa oil, apricot kernel oil, sweet almond oil as well as all other oils dominated by fatty acids from the omega-7 and omega-9 groups. As these can penetrate the hair.

High porosity

Damaged, dry, dull and fragile are some of the words you can use about high porosity hair. The hair tips are split and wrinkled easily, the hair loses volume and is generally difficult to tame. As the hair is open, moisture will easily absorb, but also easily escape again.

What should I be aware of?

As your strands of hair are open, simply wash your hair in warm / lukewarm water for the hair to receive the nourishing ingredients. To rinse out your conditioner, do this with cold water. The cold water helps the hair follicles close, allowing moisture to stay inside the hair follicles.


Look after cedar oil, castor oil, evening primula oil, safflower oil, black seed oil, grapefruit oil, linseed oil, corn oil, sunflower oil as well as any other oil dominated by fatty acids from the omega-3 and omega-6 groups. As these can penetrate the hair.

How do I find my porosity?

The Water Test:

You can do a water test with a strand of hair to test the porosity of your hair.

The procedure is as follows:

  1. Cut a strand of hair.
  2. Wash the hair with detergent or a shampoo that does not contain silicone but contains SLS (sodium laureth sulfate).
  3. Let the hair dry completely.
  4. Fill a glass with lukewarm water, prick the hair into the water so it just below the surface.
  5. Wait 3-5 minutes.
  6. Check the result.
  • If the hair sinks to the bottom, your hair has high porosity as water easily penetrates the hair and causes it to sag.
  • If the hair floats at the top of the glass, your hair has low porosity.
  • If the hair is in the middle of the glass, you have medium porosity.
