Understanding your hair prorosity is an important step in selecting the correct hair care products for your hair. Here are just a few simple steps to find out your hair porosity.
Porosity is the measure of the hair’s ability to absorb moisture. This is set by the condition of the hair’s cuticle layer (the overlapping scales of the hair shaft), and is rated as low, normal, and high. A great analogy can be to think about your hair like a sponge. When the sponge is new it is extremely porous and absorbs water thus it has good porosity. Alternatively an old sponge where the tiny holes have been damaged does not absorb water as well because it used to.
The hair shaft is made up of cuticle layers which are literally overlapping scales. When the cuticle layer of the hair is tightly woven and compact it has low porosity as it inhibits moisture going in and going out.
Low porosity hair is resistant to hair coloring and perms and should be softened to open the cuticle layers previous to a treatment. The perfect remedies for low porosity hair are deep conditioning products and products rich in moisture and/or products that contain humectants which is able to attract moisture to the hair.
High porosity hair on the other hand has an open cuticle layers and absorbs moisture and color treatments more easily. However overly porous hair releases moisture and becomes dry and dull. The best products for hair with a high porosity are moisturizes containing natural plant based oils, and mildly acidic rinse. Additionally one should avoid sulfate-based surfactants.
Normal hair porosity is somewhere in the middle. This hair texture requires the least amount of maintenance, as it should allow moisture to pass in the hair shaft as needed. Additionally hair with a high porosity will hold a hairstyle and permit chemical processes within the expected manner. However, note that repeated chemical processes can change the porosity of your hair by damaging the cuticle layer.
Below are a couple of tests you can do to figure out your hair’s porosity and help you select the fitting products to your hair.
Test 1: When washing your hair notice how long it takes in your hair to become saturated and fully wet. Hair that wets easily is porous, very similar to a brand new sponge. There is also a possibility that you just hair might be covered with to many hair care products reminiscent of oils and conditioners. Additionally consider how long it takes your hair to dry, hair that dries quickly is porous as the cuticle layers are open and allow air flow.
Test 2: Wash and condition your hair as normal. Towel dry (do not add any other products). Gather one strand of hair and run your index finger and thumb along the shaft starting from the tip of the hair strand to the root. Low porosity will feel slick, normal porosity will feel smooth, and high porosity you will feel catches as you progress your fingers down the hair shaft.
Test 3: Take a number of strands of hair (from comb or hair brush) and place in a bowl of water. If the hair sinks to the bottom of the bowl in lower than a minute or two, it is porous. If only part of the strand sinks you your hair is porous in certain areas and this is sort of common.
I hoped this article helped you to understand hair porosity and convey you that much closer to selecting the precise hair products to your hair.
