Secrets To Knowing Your Hair Porosity

Posted on March 16 2016

Every natural girl wants to know the secret to soft moisturized hair. However, before we spill our secrets for maintaining moisture, you have to do share a secret with us. We want to know your hair porosity. Oh, is that something you don’t know we’ll come close and we’ll teach you our simple tricks for learning your porosity and tell you why you need to know. Porosity measures how water flows in and out of your hair strands. There are 3 types of porosity – high, medium and low. Each type has specific needs and methods for maintaining retention. Determining your porosity is an simple process that can be done at home.

Test 1 - Porosity tests are best done on clean product free hair. To start the test pull a strand of your natural hair from your head or find a strand in a comb/brush. Run your fingers up and down the length of the strand. Document if the strand feels smooth or if it feels jagged (don’t mistake your curly texture for jagged hair). If your hair feels smooth you likely have low porosity and if it feels rigid you may have high porosity hair.

Test 2 – Get a small cup of water in a clear glass or container. Place a strand of hair in the cup of water for at least 15 – 20 minutes. If your hair sinks to the bottom of the glass your hair is high porosity. If your hair floats at the top of the water, you have low porosity hair. If your hair initially floats, then sinks after some time, then you have medium porosity hair. Here’s a tip repeat this process for each section of your hair (front right, front left, back right, back left, crown) because you may find that your hair porosity is different in each section of your hair.

Now that you, know you’re porosity we can share our secrets to catering you’re your hair needs.

High Porosity Hair

High porosity hair is usually chemically treated and/or damaged. It absorbs and releases water easily. The water flows through it freely. If you have high porosity hair, it’s best to use use thick oils and butters to seal in the moisture after you’ve hydrated your curls. The oils and butters serve as the barrier, causing the hair to hold moisture for longer periods of time. Also, after washing your hair rinse your hair with diluted apple cider vinegar to close the cuticles of your hair (don’t worry the smell will wear off after your rinse it out).

Low Porosity Hair

Low porosity hair is common to curly hair. It does not absorb water easily making it difficult to moisturize. However, once you are able to infuse water into the hair, it holds on to it. To make absorption easier add heat to your regimen. Hot oil treatments, steam treatments and plastic wraps will open the cuticles, allowing the moisture and conditioners to be easily absorbed by the hair. Your regimen should be focused on sealing moisture into your hair.

Medium Porosity Hair

Medium porosity hair is considered to be ideal. It absorbs and releases water in an ideal timeframe allowing for hair to stay moisturized. If you have medium porosity hair no adjustments are needed and you are a lucky girl indeed. Just make sure you use products with healthy ingredients – free from sulfates, parabens, mineral oils, and silicones.

Have you done the strand test on your hair? What’s your porosity and how to you adjust your regimen to satisfy your hair needs?

    Adrienne, The hot oil treatments are a great option for low porosity hair. For an added boost put on a shower cap and sit under a warm dryer.
