Porosity

The Next Important thing you need to know about your hair is it's Porosity.
Porosity is how well your hair is able to absorb moisture as well as hold it in. It is affected by the flexible outer hair layer called the cuticle, which determines how easily moisture and oils pass in and out of your hair.

There are 2 ways you can find out how porous you hair is. The Float Test and the Slip n slide test. The float test is the best way to go because it's the easiest.

The float test- take a few strands of your hair. (from the sink or comb) and put it in a cup of water. Let it sit for about 5 mins. If your hair floats you have Low porosity and if it sinks you have high porosity.



Low Porosity - Hair with low porosity has a tightly bound cuticle layer with overlapping scales that lay flat. This type of hair is usually considered healthy, and is often very shiny, especially when it's dark in color. Low porosity hair repels moisture when you try to wet it and is hard to process since it resists penetration of chemicals.
Low porosity hair is also prone to build-up from protein-rich deep conditioning products, which can leave it feeling stiff and straw-like and nasty.


Medium 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. Hair with normal porosity tends to hold styles well, and can be permed and colored with predictable results. Over time, however, these processes can damage your hair and increase its porosity.


High Porosity-  High porosity hair has gaps and holes in the cuticle, which let too much moisture into your hair and leave it prone to frizz and tangling in humid weather. Even simple acts such as bathing, swimming and shampooing can create more damage and breakage due to the sheer amount of moisture highly porous hair can absorb.


And that's it for Porosity... I no that this is a lot to take in but stay with me til the end and I will really pay off...
