Hair Porosity 101

Hair Porosity 101

The most important fact to know about your hair is its porosity (more than your hair type)! It determines the ability your hair has to absorb water/products.

 

Low Porosity Hair has a low absorption rate and have more difficulties absorbing moisture.

You may recognize that:

  • It’s hard for water to saturate the hair
  • It’s hard for natural oils/products to penetrate the hair they tend to sit on the hair and create buildups
  • Once wet, the hair takes a long time to air dry

    High Porosity Hair has a high absorption rate and have more difficulties retaining moisture.

    You may recognize that:

    • Water easily saturates the hair
    • Products easily penetrates the hair therefore it requires more products
    • The hair quickly air dries
    • Tends to be frizzy and dry
    • Hair brakes easily

       

      How to determine your hair porosity?

      The Float Test: Take a strand of your hair and drop it into a bowl or cup of water. Let it sit for 2-4 minutes for results.

        1. When your hair starts to float, it is considered to have Low Porosity
        2. When your hair starts to sink, it is considered to have High Porosity

       

      What are the must-knows of low porosity?

      • Use heat when deep treating your hair to open the hair shaft which aids with absorbing the products (hooded drier, steamer, warm towel or shower cap).
      • Use protein-free conditioners.
      • Use shampoos and conditioners that contains ingredients such as glycerin and honey.
      • Use products with oils as a sealing agent. (They tend to have a harder time penetrating the hair.)

      What are the must-knows of high porosity?

      • Regularly deep condition/co-wash the hair to regenerate its hydration.
      • Use lukewarm water when shampooing and conditioning and rinse with cold water. (Hot water may lift the cuticles and cause further damages.)
      • Use shampoos and conditioners that contains ingredients such as butters and oils.
      • Use leave-in conditioners and sealers to hydrate and keep the moisture.
      • Dry your hair a microfibre towel to avoid breakage.
