What is Hair Porosity?

Hair porosity refers to the hair’s ability to absorb moisture. Hair porosity can be broken down into three general categories, which are low, normal, and high. Understanding your hair’s ability to absorb moisture will go a long way in helping keep your hair healthy. There is a simple test you can do to see the porosity of your hair.  All you need is a strand of your hair and a glass of water. Take note of how your hair responds when you drop it in the water. If it floats on top of the water and takes a while before it starts to sink, your hair has low porosity. If your hair sinks to the bottom immediately, your hair has high porosity, and if it lingers midway in the glass, it has normal porosity.


A couple of symptoms of hair with low porosity are that products tend to build up on top of your hair rather than absorb into or if your hair takes longer to saturate when you wet it fully. The reason your hair floats on top of the water is that the cuticles are tight, making it difficult to absorb moisture. With tight cuticles, oils may sit on top of your hair and not sink into the cuticles. There are several ways you can help your hair if it is having issues absorbing moisture. Firstly, using heat (like a steamer, or warm towel) can help lift your cuticles, so they are able to absorb moisture. You’ll also want to use a sulfate free shampoo, and apply products to your hair when it’s damp.


Normal porosity is ideal, and your hair holds moisture for a decently long time. A few indicators that your hair has normal porosity is that it holds styles easily, and it may require little maintenance. Keep in mind that hair porosity can change over time. Things, like heat or chemically processing your hair, can impact its ability to absorb moisture. If your hair has normal porosity, then continue what you’re doing. You may also benefit from using deep conditioners to help your hair maintain its level of porosity.


If your hair has high porosity, it may have rips, gaps, or tears that allow for moisture to flow in easily; however, this also means that moisture can easily flow back out. Signs of high hair porosity is that you may need more products, your hair may look frizzy (even after applying products), and your hair is dry. For those with high porosity hair, it’s crucial to avoid heat. Opt for air drying your hair if possible. Rinse your hair with cold water to seal your hair cuticles; this will also help keep your hair from looking frizzy.

Moisture retention is essential for optimal hair health, but, as you can see, moisture is not just about water and oils, it has a great deal to do with the qualities of your hair as well.
