Before knowing about Low Porosity Hair, Let’s know about Hair Porosity : Here where substances are porous , Then they’ll be able to absorb fluids and Hair is Porous to maintain its porosity. So High Porosity Hair absorbs more water and Low Porosity Hair absorbs less water. In Low Porosity Hair the scales of the hair are smooth and tight to allow water reaching the core layer while washing and it takes more time to get wet and also takes more time to dry the hair. Hair consists of 3 Layers : Cuticle, Cortex and Medulla.
what is Low Porosity Hair?
The Hair which is smooth and the outer most layer of the hair strand (cuticles) are thin and closed allows less moisture or water to enter the inner most layers and reach hair shaft , in such a condition , The hair porosity is low and also the low porosity hair is more vulnerable to fall off. The low porosity hair strands are sealed and smooth, making the hair appear reflective and shiny to sunlight.
How Porous your Hair is?

To know the porosity of your hair , you can test your hair in six ways:
The Slide Test : Take your hair and hold the top part and Take a strand of dry hair and slide your fingers up the hair shaft towards the scalp and observe how you sense it. If the hair feels rough and bumpy, then you have High Porosity Hair. If you feel it little bumpy and some smoothness, then you have Medium Porosity Hair. If your hair is smooth and slippery, then you have Low Porosity Hair.
The Float Test : Take a glass of water and drop your hair in to it. If the hair floats, you have Low Porosity hair. If the hair sinks slowly , then you have medium porosity. If the hair sinks quickly to the bottom of the glass, then your hair is highly Porous.
The Spray Test : Take a hair strand and hold it tightly vertically, Spray water on the hair, If the water slips down, then you have Low Porosity Hair, If the water sinks in and disappears, then you have High Porosity Hair.
Dynamic vapor sorption: This test measures the weight of hair as it becomes exposed to humidity. It is not one that people can typically do at home.
Fiber swelling: This measures the dimensions of a hair fiber after exposure to water. It would also be difficult to do this at home.
Gas adsorption and pore size analysis: This test exposes a hair sample to nitrogen. The results show the distribution of the nitrogen that the hair absorbs and the size of the pores in the cuticle.
