Hair Porosity Explained For Black Women


Your Hair Porosity Explained


Put simply, hair porosity is a measure of how well or poorly the cortex of the hair absorbs water or chemicals. Water permeates through all hair, but the level of porosity varies from individual to individual, as well as from cuticle layer to cuticle layer.

A traumatic styling experience, like getting a perm, can damage your hair; when it is dyed, its protein structure is attacked and its protective cuticle shield is broken and torn. Hair in this condition is said to be porous.

Why does this matter?

Our hair is like a roof on a house. When it is new, it protects us from the elements. As it ages, its cuticle layers crack, peel, and lift, decreasing its ability to absorb and hold moisture. Older hair is usually more porous, and the porosity usually increases from the roots to the ends.




Low Porosity Hair For Black Women

Hair with low porosity is less likely to absorb moisture and will resist chemical treatment. There is generally little or no cuticle degradation in such hair, and the cuticle remains intact. Low porosity hair has tightly closed cuticles, as they are when the hair emerges from the hair follicle. Over time, however, chemical processes, styling stress and daily living inevitably cause the cuticle scales to lift and lose their elasticity. 

High Porosity Hair for Black Women

Hair with high porosity absorbs moisture most readily. The more damage the cuticle has endured, the greater the porosity and the greater the amount of water or moisture it tends to absorb. High porosity is typically caused by heat-styling tools, the sun, chemical relaxers, and colored hair. 

 For most people, the ideal level of porosity is somewhere in the middle: good porosity with good moisture retention, if desired, along with a willingness to accept chemical treatments. There is a close relationship between hair pH and porosity. By constricting the cuticle and tightening it, low-pH products and styling treatments reduce hair porosity.

Porosity Problems

High porosity is caused by anything that damages the cuticle, such as heat-styling tools, UV rays, chemical treatments, and sulfate-containing shampoos. In this instance, it's best to invest in natural hair products. Often when these products are used as the focal hair treatment for women they notice a number of benefits:
