It’s one of those things you hear a lot of chatter about in the Natural Hair Community.
High Porosity, Low Porosity, No Porosity…
But what really is Porosity and how does it affect your hair health and growth..
In a nutshell, porosity is your hair’s ability to absorb moisture. Kinky Koily hair is naturally
dry, so porosity plays a big role in ensuring your hair stays in good condition.
Your hair needs to absorb and retain moisture to retain length, stay healthy and grow.
Porosity plays a big role in determining the type of products that are ideal for your hair.

of your hair. High porosity hair absorbs moisture well, can get dirty easily, absorbs sweat
