Hey guys, porosity is today’s topic.
Hair porosity is basically how easily your hair takes in moisture. This is dependent on the state of your hair’s cuticles. Its necessary to know your hair’s porosity because it determines your regimen and the products you use.
There’s three types: low, normal and high porosity.
Low porosity hair has its cuticles laying flat or almost flat to the strand. As a result, its takes effort to the hair to take in moisture.
This hair appears shiny because the flat cuticles reflect light fairly easily.
Low porosity has no problem retaining moisture, but getting that moisture in is the task.
- use heat when deep conditioning to help open up the cuticles.
- seal hair with light oils to prevent build up.
- baking soda as a cleanser or rinse before deep conditioning to raise the cuticles; this is because of its basic nature.
High Porosity hair has its cuticles raised from the hair shaft. As a result, it lets in moisture easily but it doesn’t retain moisture.
This hair is frequently dry and frizzy.
High porosity hair may be due to frequent heat styling or constant manipulation which disrupt the nature of the cuticles.
- using cold water as the final rinse after washing to help close the cuticles.
- acidic products (similar to hair’s pH) such as apple cider vinegar rinses to close the cuticles.
- seal hair with heavier oils and butters to help retain moisture.
Normal porosity hair has the cuticles sufficiently raised to let in moisture and sufficiently closed to retain moisture.
Hair Porosity Tests
Naturally, the next step is to find out your hair’s porosity. I know of two:
Slide Test – holding one strand of clean hair taut, run your fingers up and down the strand; if the strand has a bumpy texture, its likely that its highly porous because the cuticles are lifted giving it the rough texture. If its smooth, its likely that it’s porosity is low because the cuticles are flat and that’s why you can’t feel them.
Water Test – place a clean strand of hair in a glass of room temperature water and leave it there for 2-3 minutes; if its still floating at the top, its likely that it’s prorosity is low becauase it hasn’t taking in enough water to become heavy and sink. If it has sunk to the bottom, its likely that its highly porous because it has taken in a lot of water and unk because of the weight. If its midway in the glass, its likely that you have normal porosity because the strand has taken in enough water to move down but not too much to sink.
I did both tests and found out that i have low porosity hair. This way I know whether the things I’ve been doing to my hair are necessary or not.
See you on the next one ❤
