How To Test, And Care For Your Hair Porosity Type

Nov. 9, 2021 · Written by Rita Okechukwu


We are all a bit obsessed about our hair type/curl pattern. Is it a 4b? no, isnt that a 4c i see at the middle section? Lol. But even more important than curl pattern and definition, Hair porosity type is vital to the health of your hair.

What is Hair Porosity



Hair porosity is simply the ability of hair to absorb and/or retain moisture. For better understanding, it helps to know more about the structure of your hair strands, which is made up of 3 layers; Cuticle, Cortex, Medulla.


                       Cuticle: Protective and tough outer layer of your hair, made up of smaller cuticle cells overlapping each other like fish scales. 


These cuticle cells allows the diffusion of moisture and oils in and out of the hair strands. Tightly packed cuticles with little openings allow very little moisture in and out while loosely stacked cuticles have bigger openings making passage of moisture easier.


Hair porosity is determined by how tightly the cuticles cells are arranged in overlap and glued on the hair surfaced.

There are three hair porosity types; Low Porosity, Medium Porosity and High Porosity hair types.

Hair porosity affects the effectiveness of hair products and practices and its a huge factor in the health of your hair. It is important to know your hair porosity and care for it appropriately. Find out your hair porosity through;


The Float Test:


  • Wash hair of all build up and dry completely.
  • Take out a few shed hair strands from comb or hair brush.
  • Fill a cup or bowl with water.
  • Drop the hair strands into the cup/bowl.
  • Let it sit for 2 - 4 mins and then check for result





  • Hair floats to the water top - Low porosity
  • Hair floats around the glass and between the top and base - Medium porosity
  • Hair strands sinks to the bottom - High porosity





The Strand Slide Test:


  • Separate a few freshly washed curl strands from different section of your head; front hairline, crown and nape.
  • With your fingers gently stretch the curl strands from any one of the three head sections.
  • Holding the curls stretched out, place them between the thumb and fingers on the other hand and slide your fingers along the hair strands in an upward direction ( i.e from the ends towards the scalp). Repeat in the other 2 head sections.




  • If the hair strands feel bumpy and rough or breaks off during the slide that means your cuticles are raised up - High Porosity.
  • But if the curl strands feels smooth - Low Porosity.



The Spray Bottle Test:


Section off a part of freshly washed hair, spray with water from your continous mist spray bottle and observe the hair reaction.




  • Water remains on the hair, forms beads and not absorbed - Low porosity
  • Water absorbed quickly into hair strands - Hair Porosity




Hair Porosity Types



Now, you have found out what porosity type your curls are, what does mean for you? how can you care for and get the best results from your hair porosity type?


Low Porosity simply means that your hair cuticles are tightly overlapping each other with very liitle spaces inbetween making for very restricted passage in and out of the hair strands. So, hair does not absorb moisture easily but retains a very good amount of moisture.


High Porosity hair type has cuticles raised and very loosely packed with lots of spaces inbetween the cuticle cells making for very free passage in and out of hairs strands for moisture and other hair products. So, hair absorbs moisture easily and loses it just as easily ( cant retain moisture ).


Medium Porosity hair types have the both of best worlds with overlapping and evenly spaced cuticle cells, having a bit more gaps than the low porosity hair types. This hair type allows in and retains just the right amount of moisture.
