High Porosity, What Does It Mean?

Determining if you have high porosity hair:

A quick way to determine whether your hair is low porosity is to collect strands from a brush or comb and drop them into a glass of water. If your hair takes a relatively short amount of time to sink, your hair is high porosity. The hair sinks quickly because there are gaps along the cuticle.

Think of your hair as a sponge. If you have high porosity hair, the cuticles of the hair shaft are not tightly bound. As a result, moisture is absorbed quickly but isn’t trapped within the hair because the cuticles remain open; after deep conditioning your hair may feel soft but after a few hours feels dry again. Because high porosity hair absorbs a lot of water, when wet, the water weighs down the hair and decreases elasticity.


Caring for high porosity hair: 

After deep conditioning, seal the hair cuticles to trap moisture in using one of the following methods:

  • ACV (apple-cider vinegar) rinse as your final rinse. Our hair has a natural pH balance of 4.5-5.5. ACV has a pH level of 3. Diluting ACV in water and rinsing your hair with the solution will help seal the cuticles.
  • Use light conditioners with pH balances of 4.5-5.5 as your final rinse to seal your hair cuticles.
  • Roux Porosity Control as the final step in your wash. For more on Roux PC, check out this post: How To Use Roux Porosity Control.
  • Clear or color rinses. Clear/color rinses correct porosity because they contain proteins that bind to the hair shaft.
