Porosity affects certain hair types more than others, like curly hair due to the lack of moisture. You may be anxiously wondering if your hair’s moisture levels contribute to those pesky strands lingering in the drain. Well, brace yourself – hair porosity alone isn’t a direct cause of hair loss.
Don’t shampoo too often
Chambers-Harris likes to use a straw to explain low porosity hair. "If you have a straw and put holes in it, you can take in the liquid easily, but you can't retain the liquid. Once you take it out of the liquid, it's all going to run out of the straw." In addition to hair treatments, too much ultraviolet exposure can also increase the porosity of your hair.

Alternatively, you can use a more accurate scientific assessment. The float test involves placing a clean strand of hair in water to see if it sinks or floats. When placing strands of hair in water, the hair strands will absorb water.

Gas adsorption and pore size analysis is a scientifically rigorous method for measuring hair porosity with great accuracy and precision. However, it necessitates specialized equipment and technical expertise, and it is typically performed in a laboratory setting, making it unsuitable for home use. The method is particularly useful for researchers seeking to study hair properties in-depth or for companies developing hair care products designed to cater to various hair types. As oils and other treatments aren't easily absorbed, you can notice product buildup on the scalp for those with low hair porosity. Overall, low porosity hair is shiny and often considered to be healthy but tends to fall flat.
If your hair has experienced any of these factors, your curls may require protein-rich products. Using a protein hair treatment could help to repair some of the damage done to your hair and help you achieve strong curls. If you want to know what types of ingredients and products tend to work well for low porosity hair, here are some suggestions.
Now that you know how to measure hair porosity use these simple methods and get testing! Once you determine your type, you can read all about improving it below. Grab a few locks of clean hair, because any product residue can alter the results.

If the hair floats at the top then it is low porosity, if it sinks slowly or settles in the middle it is medium/normal porosity, and if it sinks straight to the bottom then it is high porosity. However, there are certain ingredients that can make low porosity hair easier to care for. Knowing the types of products to use, and which ones to avoid, can make a difference in the manageability and health of your hair.
It is seen, however, that heat is influential in raising the cuticle, irrespective of the level of heat and the duration of exposure. It’s important to note that everyone’s hair is different as well, meaning certain factors will cause more porosity in certain people than others. Outside of the above causes, porosity can also be caused by exposure to dirt, flat ironing, blow drying with too much heat, cyclical thermal stresses, and humidity. Ultraviolet (UV) radiation can also damage your cuticles starting at approximately 200 hours of UV exposure. The cuticle is not intact and cannot perform its job, which is to seal shut – retaining the moisture. Finding the right way to nourish your hair can be quite the journey, especially if you can't get your hands on the right products to keep your hair in shape.
Why Does My Hair Dry So Fast? Understanding Porosity & Care (
Recognized for her hands-on experience and trusted guidance, Tina turns every strand into a statement of beauty and confidence. The strand burn test for hair porosity is a method that observes how quickly the hair burns, the smell of the smoke, and how the hair behaves as it burns. This test is typically done by hair professionals and is not recommended for home use. The test involves comparing the drying time of hair and skin but is not solely focused on how fast the hair dries compared to the skin. The test is more specifically concerned with the rate of moisture loss from the hair strand. If low porosity is caused because of product buildup, you can bring it back to medium porosity with the help of a clarifying shampoo.
Hair porosity can be impacted by your genetics or your hair grooming routine. It’s possible to have hair strands of multiple porosity levels on your head and even have different levels of porosity within a single strand of hair. This is actually where the issue lies, especially when it comes to curly hair. If coconut oil prevents water from getting into the hair shaft, it can lead to hair that becomes drier or more brittle over time. "Coconut oil can coat the hair shaft. When using it alone, it can become a barrier to water and any other product to hydrate the hair, thus making the hair drier," she explains. Porosity in hair is natural and refers to the hair’s capacity to absorb moisture and product.
Using a protein treatment can help fill in the areas in your cuticle that have damaged cells. This can help smooth the cuticle down and create a protective coat over the hair shaft. I'll start this off by talking about some of the benefits coconut oil can offer the hair. Coconut oil can help prevent protein loss in the hair because the proteins found in it are really similar to those in our own hair.
This is important as your hair's porosity is an indicator of its health. Low porosity hair is typically considered healthier, whereas high porosity hair is more damaged. Depending on what you currently have, your haircare routine may or may not be making matters better or worse. Whether due to genetics or hair damage, high porosity hair allows moisture to be absorbed into the hair shaft easily, yet it isn’t able to retain moisture for long. This is because the cuticles tend to have gaps or spaces between them. Hair porosity is your hair’s ability to absorb and retain moisture.
These aren’t the kind of tests that can be reliably conducted at home. If you don’t feel anything and it’s smooth sailing from tip to root, your porosity is low. Before I explain the potential problems with these DIY hair porosity test methods, it’s important to understand how these tests are often conducted. The hair cuticle rises when the hair is wet, and people will need to wet their hair and handle it regularly. It is possible, however, to take steps to reduce the amount of damage done to the cuticle. It is impossible to feel a raised cuticle by running fingers through the hair unless you have severely damaged cuticles.
Before shampooing, I suggest prepping your hair with a nourishing oil. Find a sulfate-free shampoo to clean your hair without stripping away natural oils. Then, use a deep conditioner that balances your hair’s protein and moisture. Afterward, seal the deal with a water-based moisturizer to optimize hydration levels. Medium porosity hair has an even balance of water absorption and retention due to evenly raised cuticles throughout the hair shaft. Water and products can easily pass through the cuticle layer without drying out too quickly.
She also notes that products with silicone can help temporarily retain moisture. Hair with “normal” levels of porosity will absorb 75% of the maximum water possible within four minutes. People with normal porosity hair usually have an easy time getting their hair to hold bleach, hair dye, or relaxer, and the results tend to be predictable.
