I am sure many of you have heard of the old hair in a cup of water trick to determine your hair’s porosity. That’s junk science by the way and does not prove anything!
JC, a scientific beauty blogger at the Natural Haven addressed this a long time ago in a post entitled, Junk Science – Hair Porosity Tests / Float or Sink:
“Hair in general will almost always float in water. Many of you doing this test will note that your hair will float for ages and it may take some prodding to make it sink if it does at all. This is because hair is generally covered in oil. This oil is naturally produced sebum and any extra that you may use in your hair care routine will have an added impact. Now oil will always float on water, so your hair floating does not mean that it has low porosity. It does mean that your hair is light (which it is) and has a coating of oil that repels water (which it does). ”
Thankfully, we have a source that has done an exceptional job of making it easy to understand what hair porosity exactly is with a nifty sponge experiment. Erica aka Sister Scientist breaks it down for us in the video below. If you find this info helpful visit her site or follow her on Instagram, YouTube, Facebook or Twitter
“Porosity is defined as your hair’s ability to absorb water or other chemicals into the shaft of the hair. All hair is porous but your level of porosity will vary based on genetics and the amount of damage that the cuticle layer has been subjected to. Processes such as coloring the hair, heat styling or relaxing are examples that can affect increase the porosity of hair. Also, daily maintenance such as detangling and shampooing can sometimes affect the cuticle layer.
Porosity is usually measured as being low, medium or high. Highly porous hair absorbs a lot of water, but it also means it released moisture fast, meaning it is harder to keep highly porous hair moisturized! Low porous hair will hold on to moisture longer, but it is more difficult for the hair to pull in the water. “
HIGH POROSITY RECOMMENDATIONS
If you have high porous hair, you want to make sure you are:
1) Deep conditioning hair to help seal damaged spots on the cuticle surface
2) Sealing hair with oil or silicone based product to help prevent moisture from escaping your hair
3) Incorporate an Apple Cider Vinegar rinse every now and then to lower the ph of hair which will help to close cuticles tighter and trap moisture in

LOW POROSITY RECOMMENDATIONS
If you hair with low porosity, or it’s considered resistant, you can help infuse moisture into the hair by:
1) Incorporating a steamer into your hair care regimen
2) Using humectant rich products to draw moisture to the hair, especially in humid climates
3) Soak the hair in alkaline water for a few minutes just to slightly increase the pH of the hair, thus opening the cuticle more and infusing more moisture into the strand.
