How to Determine Your Hair Porosity Type at Home

Determining your hair porosity at home is a simple process that involves a few tests. Here are three common methods you can use to identify your hair porosity type:

1. Float Test:


  1. Take a few strands of clean, shed hair. Make sure the hair is free from any products or oils.
  2. Fill a bowl or glass with room-temperature water.
  3. Place the hair strands in the water and observe their behavior.


  • Low Porosity: Hair floats on the water's surface.
  • Normal Porosity: Hair strands hover in the middle of the water.
  • High Porosity: Hair sinks to the bottom of the bowl.

2. Slip 'n' Slide Test:


  1. Take a strand of hair and hold it between your fingers.
  2. Slide your fingers up and down the hair strand.


  • Low Porosity: Hair feels smooth and resistant to sliding.
  • Normal Porosity: Hair has a slight resistance but moves smoothly.
  • High Porosity: Hair feels rough or bumpy as you slide your fingers up and down.

3. Observation:


  1. Observe how your hair reacts to water and products.
  2. Pay attention to how quickly your hair gets wet, how long it takes to air-dry, and how it interacts with hair products.


  • Low Porosity: Slow to absorb water, takes a long time to air-dry, and products may sit on the hair without being fully absorbed.
  • Normal Porosity: Absorbs and retains moisture well, manageable with various products.
  • High Porosity: Quickly absorbs water but loses moisture rapidly, may feel dry and frizzy even shortly after moisturizing.


  • Clean Hair:

    • Ensure your hair is clean and free from product buildup before conducting these tests.
  • Multiple Tests:

    • Consider using a combination of these tests for a more accurate assessment.
  • Representative Samples:

    • Take hair strands from different areas of your head to get a comprehensive view.
  • Observe Over Time:

    • Keep in mind that hair porosity can change, so it's beneficial to reevaluate periodically.

Once you've determined your hair porosity, you can tailor your hair care routine to better suit the needs of your specific hair type. Understanding your hair porosity helps you make informed decisions about the products and techniques that will work best for keeping your hair healthy and well-moisturized.
