So
what is porosity? Actually it’s really simple, the hair’s ability to
absorb water. But there’s still a little more you need to know. There
are 3 levels of porosity and knowing these levels will help you create a
better hair care regimen for your natural hair.3 Levels of Porosity:
High Porosity
– hair with high porosity is considered to be overly porous. Hair that
is high porosity easily allows moisture in but moisture also easily
escapes. This means that the cuticle layers are lifted and more open.
Hair cuticles that are damaged due to excessive heat styling tools,
chemical relaxers and color usually fall within the high porosity
category.
Normal Porosity
– the cuticle layers are more lose and allows the right amount of
moisture to enter while preventing too much from escaping. The hair
usually absorbs water, moisture, and chemicals as expected based on its
hair texture. Hair with average porosity is considered normal.
Low Porosity
– hair that has not been exposed to harsh cuticle treatments is
considered to be healthy and has low porosity. The cuticle layers lie
flat and tight and very little moisture is allowed into or out of the
shaft. Also, hair with low porosity requires more alkaline solutions to
lift the cuticle and permit uniform saturation.
Being
able to identify your hair porosity level will help you select the
right products for your hair and make better product purchasing
decisions.
