How can you know the degree of porosity of your hair (and how to take care of it)

Porous hair is synonymous with frizz. Find out if yours is and learn to take care of it properly to say goodbye to frizz.

22% of Spanish women complain about the frizziness of their hair, a feature that makes it difficult to comb the hair. The porosity of the hair, determined by how open the cuticle is (the outer layer of the hair), is fully related to the frizz: the more open the cuticle is, the hair will have more gaps in which water can enter, making let the mane swell; But when the cuticle is well sealed the water molecules are too large to penetrate the hair shaft and cause the dreaded frizz.

To know if your hair is porous or you cannot do a simple test in your own home. Take a stand and place it right on the surface of a glass full of water at room temperature – the water cannot be hot because it opens the cuticle and, therefore, the hair will absorb it and sink, regardless of its porosity. If your hair is very porous it will quickly absorb water and then sink to the bottom; if it stays floating towards the middle of the glass it means that its porosity is medium, and if it is low the hair will show resistance to water floating towards the surface, even after a few minutes.

If your mane has a high porosity it will easily curl when exposed to moisture and will become drier and brittle with the dry heat transmitted by styling tools. Therefore, you have to take care of it with moisturizing, nourishing and softening products that contain in its formula jojoba oil, shea butter, aloe or avocado, since these also form a moisture barrier.

Also, it is important that, regardless of how your hair is (straight, curly, dyed, fine …) use a shampoo without sulfates, as these can get to dry out a lot. And always apply it with warm water, because if the temperature is too high it will accentuate the frizz. And never forget the conditioner and apply a moisturizing mask once a week.

And to dry your hair, it is preferable that you invest in a microfiber towel, as it absorbs moisture much faster than cotton, preventing hair from curling too much. Finally, use a good thermal protector if you are going to use the dryer and finish with a styling product that helps you block moisture.
