Hair porosity refers to how well hair can absorb and retain oils and moisture.
Low porosity means that your hair structure doesn’t allow for moisture to penetrate your shaft. This can make it more difficult for water to penetrate your hair after washing.
This type of hair is more difficult to style and process because it tends to repel moisture.
Let’s look closer at low porosity hair and some tips on how to best care for it.
What’s low porosity hair?
Hair is basically a collection dead cells that have been arranged in a three-layer arrangement.
- The cuticle , which is the outermost layer of hair, is what you call your . Each cuticle is layered like tiles on a roof.
- The cortex layer is the thickest and middle layer. It is made up of fibrous proteins and pigments, which give hair its color.
- The medulla , which is the innermost, central layer of the hair shaft, is called the medulla .
Low porosity hair tends to have the cuticles overlapping each other and being tightly packed together. It is difficult for water and products such as oils and conditioners to reach the hair shaft because there is no space between the cuticles.
Low porosity hair is usually due to genetic factors.
Low hair porosity is not usually caused by chemicals or heat.
High porosity hair is more likely when heat or styling causes damage to the cuticle layer. This means that the cuticles are higher and have more space between them. This can make it difficult for the hair shafts to retain moisture.
What characteristics are low porosity hair?
Hair products can be found on your hair
Low porosity hair may cause hair products to stick to your hair rather than being absorbed.
You might apply oil to your hair’s ends. You may find that the product remains on your hair after half an hour. You may feel it on your fingers.
Most likely, your hair absorbed very little of the product, if any.
It takes more time to wash and dry.
Low porosity hair can make washing and drying more difficult than you might expect. Water is not easily absorbed so it may be hard to get your hair wet enough to allow the water to penetrate your hair.
Once your hair is damp, drying it can take quite a while. It may take longer to dry your hair than for someone with the same hair length and thickness.
How to test hair
Here’s a simple way to determine your hair porosity. Follow these steps:
- To remove product buildup, shampoo your hair and rinse it well. For the best results, clean hair is better.
- Do not dry your hair.
- Drop a strand of hair into a glass of water.
- To see how your hair floats, watch the hair strand.
What the float test can reveal about you
Low porosity hair that seems to float to the top and then sinks toward the bottom is likely.
Hair floating in the middle of the glass is likely to have medium porosity.
The hair that sinks quickly to the bottom of the glass is usually more porous. It has high porous.
How to take care of low porosity hair
Low porosity hair may lead you to use more product or multiple products at once to try to get your hair saturated.
Because the cuticles are so close together it is unlikely that any product can penetrate.
It is important to choose products with low porosity. These products will be able to penetrate your hair more effectively.
A second important tip is to only use products on hair that is damp and warm. The heat can lift the hair cuticle, which allows oils and moisture to penetrate the shaft more easily.
Here are some recommendations for products and ingredients that work well with low porosity hair.
You want shampoos that leave no residue. You should look for shampoos that contain honey and glycerin. These ingredients penetrate hair cuticles more effectively than oils.
