Scientifically, the definition of porous is having minute spaces or holes through which liquid or air may pass. Porosity, in terms of hair, is in short, used to describe your hair’s ability or inability to absorb water. Porosity ranges from low, normal, to high porosity, with normal porosity being the ideal condition you would like your hair to be in. Porosity plays a huge role in the health of your hair. Let’s start by breaking down the different ranges of porosity.
1. Low Porosity:What does it mean to have low porosity hair? This typically means that the cuticle of your hair lies flat, making your hair’s ability to absorb moisture a challenge. Hair with low porosity is typically more difficult to process than normal porosity or high porosity. When I use the word “process” I mean the hair is more resistant to chemically straightening, texturizing, or even hair color. When the hair is exposed to water or water based products, the water or products may just sit on top of the hair. This may leave your hair feeling very dry.
How to combat low porosity hair: When you deep condition your hair make sure you are sitting under the hair dryer for about 15-20 minutes. Your cuticles will be slightly lifted causing your hair to absorb and retain moisture. Also, you can put a plastic cap on your hair for a couple of hours or sleep with a plastic cap overnight under your satin scarf. This will help create a moist, humid environment for your hair which will help you absorb moisture into your hair. Using moisturizers rich in emollients such as shea butter and coconut oil will also be beneficial to your hair.
2. Normal Porosity:Hair with this type of porosity normally gets the proper moisture with the least maintenance. The cuticle layer is looser allowing just the right amount of moisture to enter your hair and helps prevent the moisture from escaping.
How to combat normal porosity hair:Consider yourself lucky!
3. High Porosity:High porosity hair is normally the result of damage from chemical processing or environmental damage. The cuticles of your hair are raised which causes too much moisture to enter your hair leaving your hair prone to frizziness, and it also allows moisture to leave your hair easily.
How to combat high porosity hair:Using a leave-in conditioner, a moisturizer, and a sealant is very important! Sealing your hair is very important, this helps keep the moisture in your hair. Also using anti-humectants products may help your hair retain moisture by sealing your cuticle layer! Sealing in your moisturizer and leave-in conditioner is the key for combating high porosity hair!
