Hair density and porosity are two curly terms that can be confusing when you’re first starting out. We’ve looked at hair density, so now it’s time to figure out hair porosity. Your unique hair porosity often determines which products you should be using and how to style your curls most effectively. Like hair density, there’s also 3 types of porosity - low, medium, and high.
What is Hair Porosity?
Hair porosity refers to how well your hair absorbs and retains moisture, which depends on how open the cuticles are on your hair strands. While genetics play a role, factors like heat, hair dye, or bleaching can increase your hair's porosity, often leading to damage.
How to Test Your Hair Porosity
A simple method to test hair porosity is to place a clean, product-free strand of hair in a glass of water.
- If it floats, your hair likely has low porosity.
- If it sinks slowly or stays in the middle, your hair is usually medium porosity.
- If it sinks immediately, your hair most likely has high porosity.
Keep in mind that this test only offers a basic indication and isn't a precise measurement.
