What’s Hair Porosity

All About Hair Porosity 

Hair porosity is basically how porous your hair strands are and how well your strands can receive moisture. Knowing your hair porosity will help you determine what you need to change in your regimen to receive moisture properly.

How can you tell what your hair porosity is?

This is totally easy. To test what your hair porosity is, just take a cup of water, preferably room temperature, and place one strand of hair in the cup. Now, don’t pull your hair out of your head! Take a strand of hair from when you’re detangling. This will only take a second. Watch to see if the strand stays floating on top of the water, in the middle of the cup or has sunken to the bottom. If the strand stays on top, you have low porosity hair. If the strand is in the middle of the cup, then you have normal porosity hair. If the strand has sunken to the bottom, you my friend have high porosity hair.

What does this mean?

Low porosity hair:

Low porosity hair means that moisture has a hard time penetrating through your hair strand. Along your hair strand, there are cuticles or little flaps that allow moisture to move easily through the hair shaft. With low porosity hair, your cuticles are compact and closed most of the time. TIPS: Avoid products with alcohols and thick butters which dry out your hair and cover your strands allowing no moisture to penetrate through your hair. Use light oils like grapeseed oil or jojoba oil  to seal in the moisture. Avoid cold water/vinegar rinses which close the cuticles and smooth the hair shaft. Your hair cuticles ALREADY are closed. Rinse your hair with warm water to keep those cuticles open for some time to receive the moisture from conditioning. Use a hair steamer to add moisture to your hair during prepoos and deep conditionings. Being a low-po myself, I can definitely relate to this.

Normal porosity hair:

Normal porosity hair means that your lucky self has no problem receiving and retaining moisture. TIPS: Search for moisturizing conditioners that can also be leave ins. Avoid heavy protein conditioners and use different oils to seal in the moisture.

High porosity hair:

High porosity hair means you have a hard time keeping moisture in because your cuticles are open which allows moisture to leave your hair. TIPS: Avoid heavy silicones and drying agents. Use heavy butters and rinses to help close your cuticles. Aloe vera juice is also good at closing your cuticles.
