So I'm thinking my hair suffers from high porosity. Porosity is defined as the ability of the hair's cuticle to retain moisture. The higher the porosity, the harder it is to keep your strands quenched. High porosity is a common problem among those with corkscrew type curls like mine. (Chemical and excessive heat treatments can also result in high porosity due to damaged and raised cuticles) So how do I fix it? I've been doing my research and it led me to this awesome article on cushblog.com about what high porosity means and the do's and dont's of dealing with it. If your hair is constantly dry (especially in winter months) no matter how much you condition it, oil it, or butter it up... you should check it out.
How to Correct Dry Hair Caused by High Porosity
If you suffer from it’s because the hair system is not properly hydrated.
Healthy hair typically has 6% moisture. When the hair system becomes dry, it’s typically found in hair that has high porosity.
High porosity hair has raised cuticles that will not hold moisture in the cortex or cellular membrane complex. The twisted, elliptical, corkscrew hair shaft structure for type 4 hair makes it particularly susceptible to raised cuticles (i.e. high porosity) and ultimately breakage at those points where the hair makes a 180-degree bend. If your from excessive flat ironing, coloring or mechanical stress, the problem of dryness gets much worse.
