The ability of your hair to absorb and hold water is called its porosity. Depending on how your hair is made on the inside, you may have high, medium, or low porosity hair.
The porosity of your hair can tell you if it is damaged, needs more moisture, or is healthy. Some people have completely changed how they take care of their hair since they found out how porous it was. Porosity is more important than the natural hair scale for people with curly or black hair.
Vicky Bridge-Tonner, who is known as the "Queen of Curls" on Instagram and in Manchester, UK, says that you should try the porosity float tests.
Jenny Roberts, a hairstylist and expert on afro-textured hair, says that you can also "drench" your hair with water. Hair with a high porosity has very thin strands that get wet quickly. You want products that don't weigh your hair down too much. Conditioners with oils are recommended by experts because they seal in moisture.
Reduce the amount of heat you use to style your hair, or use a lower setting and heat protector sprays. Vicky says that people with high porosity should be careful when trying to add moisture to their hair with oils.
Is it more important to know your hair's porosity than its type if you have curly, natural hair? You can tell if you have 1a hair (the straightest) or 4C hair (the most wavy) by learning which products, techniques, and other tips are best for your hair type. To avoid "breakage," people with low porosity hair should be careful when using protein shampoos.
Vicky also says that curly hair with low porosity is "sensitive to protein."
“If you know what type of hair you have, you might be able to put together the right routine for your hair. Even though porosity is mostly determined by genes, it can be changed by things like heat and chemicals used on the hair. If you don't use enough products that hydrate and moisturize your hair, it can get frizzy, break, lose its curls, and look dull and dry,” she explains.
