Porosity refers to the ability of the hair to absorb and retain moisture. This also includes the rate at which water and / or topical products applied to the hair are absorbed by the strands. The more porous your hair is, the more moisture it can contain, making it healthier and easier to manage. During the course of life, porosity can change.
What does hair prosperity mean?
To understand the concept of hair porosity, it is helpful to know a little about the structure of your hair, which consists of three layers. These layers include:
The Cuticle – This is the tough, protective outer layer of your hair that is made up of smaller cuticles that overlap each other, similar to shingles on a roof.
The cortex: Thickest layer of hair is called Cortex. It contains fibrous proteins and the pigment that gives color to your hair.
The medulla: this is the soft central part of the hair shaft.
For your hair to stay healthy and hydrated, water, oils, and other moisturizing products must be able to pass through the cuticle to reach the cortex.
But, if the cuticles are too close together, it is not easy for water and oils to penetrate the hair. This can make it difficult for your hair to get the moisture it needs.
Also, if the cuticles are too far apart, your hair will have a harder time retaining moisture and staying hydrated.
There are three levels of capillary porosity, so let’s take a closer look at this.
1. HIGH POROSITY
If someone has high porosity, it means they have a hard time keeping hair hydrated. And, even with regular care, the texture and overall appearance of hair can appear dry … controlling frizz is also more difficult. This is because the hair cuticle has signs of damage. The cuticle is the outermost layer of the strand. If you looked closely, you would see cracks, cracks, and uneven texture. A person with high porosity hair can absorb moisture quickly, but can also lose it just as easily. In order for the hair to retain moisture, the follicle must be “closed”, but in this situation the process is difficult. As it ages, hair naturally tends to develop a higher level of porosity. Things that speed up this process are long-term use of chemicals and exposing hair to high heat levels from dryers, flat irons, curling irons etc.
2. NORMAL POROSITY
If you have normal hair porosity, you are winning! Balanced hair is generally healthy and the follicle can absorb and retain moisture with minimal problems.
3. LOW POROSITY
When you are young, hair generally has a lower level of porosity. Having low porosity means that the hair follicle does not absorb moisture as fast as high porosity hair. This also means that water and topical products do not penetrate hair easily, and have little or no effect. Despite the fact that the cuticles are healthy, the hair can still have a dry appearance.
There is a test you can do to determine your level of porosity. Get a clear glass and fill it halfway with water. Put a lock of your hair in the water and wait about 5-10 minutes. If your hair floats on water, it has LOW porosity. If it hangs in the middle of the water, it has NORMAL porosity. If your filament is sitting at the bottom of the glass, it has HIGH porosity.
Regardless of your hair type or texture, hair porosity can be determined in the same way.
If you have high porosity, try applying a deep conditioner or protein treatment to your hair once a week. It will also provide some relief to brittle and damaged hair. Wash the conditioner with cold water, this helps to close the follicle and seal in moisture.
If you have low porosity, try using a vaporizer and apply products that are rich in moisturizers.
Once the cuticle has been damaged, the focus becomes on preventing further damage. We know that excessive heat and chemical processes contribute to this damage; if possible, let’s start eliminating or reducing the frequency of those routines. Try to let your hair air dry overnight. If that’s not possible, invest in a hair dryer that you can sit on. Usually it has three temperature settings, choose low or medium if you can. Hair may take longer to dry, but hair health should be the priority.
Also, limit sun exposure, too much direct sunlight on hair can also remove moisture. If you must be outside for an extended period, cover it with a scarf or hat.
