Hair 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.
Melissa's Video Highlights:
- You cannot change the level of porosity you were born with but you can change how large the cuticles on your hair shaft enlarge by limiting the manipulation of your hair in its entirety.
- If you have highly porous hair it's suggested to occasionally try an apple cider vinegar rinse in order to lower the pH of hair which will help to close cuticles tighter and trap moisture in
- If you have hair with low porosity that is resistant to moisture you can help infuse moisture into your hair by incorporating a hair steamer into your hair care regimen.
- Another cool tip for low porosity hair is to soak your hair in natural alkaline water for a few minutes just to slightly increase the pH of it, this helps open the cuticle more and infuses more moisture into the hair strands.
