How to Determine Your Hair Porosity

How to Determine Your Hair Porosity

Determining your hair porosity level is an essential step towards understanding how your hair interacts with moisture. Here are a few tests you can perform to identify your hair porosity:

  1. The Water Test: Take a strand of clean hair and place it in a glass of water. Observe how your hair behaves. If it sinks quickly, you likely have high porosity hair. If it stays afloat for a while, you may have low porosity hair. If it sinks slowly to the middle of the glass, it suggests normal porosity hair.
  2. The Slip ‘n’ Slide Test: Take a strand of hair and gently run your fingers up the shaft from the ends to the roots. If your fingers move smoothly, your hair likely has low porosity. If your fingers catch or feel rough, you may have high porosity hair.
  3. The Spray Bottle Test: Spritz a small section of your hair with water. Observe how the water interacts with your hair. If the water beads up and takes a while to be absorbed, you likely have low porosity hair. If the water is quickly absorbed and your hair feels damp, you may have high porosity hair.

Remember that hair porosity can vary throughout your hair, so it’s important to test multiple sections to get a comprehensive understanding of your hair’s porosity level.

Understanding Low Porosity Hair

Characteristics of Low Porosity Hair

Low porosity hair has a tightly bound cuticle layer, which makes it more resistant to moisture absorption. The cuticles lay flat and can be challenging for moisture to penetrate, resulting in your hair taking longer to dry. Some common characteristics of low porosity hair include:

  • It repels water and is slow to absorb moisture.
  • Products tend to sit on the hair instead of absorbing.
  • Hair may feel coated or weigh down easily.
  • It is prone to product build-up and can become greasy quickly.
  • It can be resistant to chemical treatments such as hair dyes or perms.

Best Products for Low Porosity Hair

When it comes to caring for low porosity hair, it’s crucial to use products that penetrate the hair shaft effectively and provide adequate moisture without causing product build-up. Here are some recommended products for low porosity hair:
