The long awaited sequel to What Type of Hair do you Have? is here! To be honest, I forgot I had a Part 1 that was left incomplete. I didn’t like leaving it hanging, so better late than never.
In What Type of Hair do you Have? Part 1 we went over 4A, 4B, and 4C hair as well as the hair products suggested for each one. Now we’re going over the differences between high porosity hair and low porosity hair, and what that all means.
What is Porosity?
It sounds kind of weird and hard to understand at first, but it’s actually pretty simple. Porosity is basically the hair’s ability to absorb moisture. It can be broken down in 3 categories: low, medium, and high porosity.
But how do you know what category you’re in? The Porosity Test is a good way to figure that out.
The Porosity Test
First, get a strand of clean hair and drop it into a glass of lukewarm water. If the strand immediately sinks to the bottom, you have low porosity. If it sorta lingers in the middle, you have normal porosity. And if it the strand floats on the top and takes a while to sink down, you have high porosity.
Low Porosity: Hair with low porosity is resistant to hair dyes and perms, also to conditioners and moisture. Product builds up easily, making the hair feel dry and brittle.
Normal Porosity: Hair with medium porosity often requires the least amount of maintenance. The cuticle layer is looser, allowing just the right amount of moisture to enter while preventing too much from escaping. Over time, processing your hair can damage it and increase its porosity.
High Porosity: Hair with high porosity takes moisture in easily, but also loses moisture as well. This is usually caused by damage from perms, heat, or hair dyeing. This type of hair is more prone to breakage and looks dry.
So now you know what types of hair porosity you have, but what type of products should you use? That’ll be in Part 3 of What Type of Hair do you Have.
