Understand your hair porosity: A comprehensive guide to care and repair
Have you ever wondered what the ingredients in your hair care products might reveal about your hair's porosity? Whether it's aloe vera, glycerin, or honey – these humectants can cause frizz in medium to high porosity hair. However, in low porosity hair, they can make it appear dull and limp.
Oils, butters, and emollients aren't always the best choice for every hair type. While they work wonders on high-porosity hair, they can weigh down low-porosity hair. Coconut oil is a perfect example—a favorite for low-porosity hair, but often a cause of frizz in high-porosity hair.
In this article, we'll explore the different aspects of hair porosity and the effects of various ingredients on different porosity types. Stay tuned to learn more about caring for your hair based on its porosity.
Hair structure and porosity
Hair structure is complex and diverse, with porosity playing a crucial role. Determining your hair's porosity level is essential for finding the optimal care program.
What is hair porosity?
Hair porosity refers to the condition of the cuticle, the outermost layer of the hair shaft. Depending on its degree of openness, this protective layer can absorb more or less moisture and nutrients. The hair's ability to absorb and retain moisture is directly dependent on its porosity. With high porosity, the cuticles are wide open; the hair soaks up water like a sponge but also loses moisture quickly. Conversely, with low porosity, the cuticles remain closed; water can barely penetrate the hair structure.
Identifying the three porosity levels
There are three different types of hair porosity: low porosity, normal and high porosity.
- Low porosity: This hair type has a closed cuticle layer. Therefore, few substances can penetrate, but moisture is retained in the hair for longer.
- Normal porosity: With this hair type, the porosity is in the middle between high and low. It absorbs a reasonable amount of moisture and retains it well.
- High porosity: Highly porous hair is brittle, rough, and dry. This type absorbs a lot of water but cannot retain it for long.
To determine hair porosity, there are various methods such as the water glass test or the touch test. In the former, a strand of hair is placed in a glass of water; if it sinks to the bottom, the hair has high porosity. In the touch test, hair feels rough with high porosity and smooth with low porosity.
Determining your own hair porosity
Knowing your hair porosity is crucial for choosing the right hair care routine. The following explains various methods for determining porosity to help you gain a deeper understanding of your hair's characteristics.
The Float Test: A Guide
The float test is a simple method for determining your hair porosity. A single strand of hair is placed in a glass of water, and it's observed whether it floats or sinks. Hair that floats indicates low porosity, as its cuticle remains closed and repels water. However, if the hair sinks, this indicates high porosity – the cuticle is open and absorbs moisture more easily.
It's important to note that this test is not 100% accurate. Factors such as product residue can distort the result. Nevertheless, it provides a good starting point for assessing your own hair porosity.
Other methods for determining porosity
Besides the float test, there are other ways to assess hair porosity:
- The touch test: In this test, you run your fingers over a single dry and clean hair from root to tip. If the hair feels smooth, it likely has low porosity. Conversely, if you feel any unevenness, this indicates increased porosity.
- The spray test: This test involves spraying the hair with a little water. If the water is absorbed quickly, the hair porosity is likely high. However, if it remains on the hair for longer, the porosity is more likely to be low.
- Observing drying time: Hair with high porosity tends to dry faster than hair with low or medium porosity, as it loses moisture more quickly.
These methods together can provide a broader insight into the condition and needs of your hair and help you develop a suitable care routine.
Care recommendations for different porosity types
In this section, we present specific care strategies for the three hair porosity levels: low, medium, and high. It's important to note that each of these levels exhibits different behaviors regarding moisture absorption and retention. Therefore, each type requires a different care routine.
Care tips for low porosity
Hair types with low porosity retain moisture better than others and therefore require less protein. An overload of protein can make hair dull, dry, and prone to breakage. Lightweight products like protein-free conditioners are ideal because they easily penetrate the hair shaft and are unlikely to cause unwanted product buildup. A helpful tip is to dilute the conditioner with water and dampen the hair before application to optimize moisture absorption.

Care tips for medium porosity
Medium-porosity hair absorbs conditioner quickly and remains soft and silky. This suggests that this hair type needs a balanced amount of protein. It is recommended to use a conditioner that contains both moisturizing and protein-rich ingredients.
Care tips for high porosity
Highly porous hair is severely damaged and quickly absorbs but also loses moisture. This type of hair requires a high amount of protein for repair. Lightweight products like protein-rich foams or gels are ideal for sealing the hair cuticles and thus preventing moisture loss. Another tip is to wash your hair regularly with clarifying shampoos to remove product buildup and improve the absorption of conditioning products.
Causes and influencing factors of hair porosity
High porosity indicates a significant degree of hair damage. Characteristic features include brittle, rough, weak, split ends, dullness, and dryness at the ends. Hair is often stiff and fades, either due to sun exposure or as a result of pigment washing out after coloring. This high sensitivity means it is easily damaged. For example, the disulfide bonds in the hair can be broken by using flat irons, curling irons, or hair dryers.
Hair porosity can be determined at home. Proven methods include reading ingredient lists and observing how the hair behaves after applying certain products.
Another cause of high porosity is years of exposure to chemical dyes and intense heat. In this case, the hair has a high absorption capacity for water but loses moisture just as quickly. This makes it more susceptible to damage and intensifies the effects of chemical dyes, heat, or sun exposure. It breaks easily because it consists mainly of unprotected hair medulla.
In such cases, experts recommend proteins to repair and nourish the affected hair. These strengthen the hair and contribute to restoring its natural structure.
Conclusion
Hair porosity is a crucial factor for hair health and beauty. It determines how well hair absorbs and retains moisture. Simple tests like the water glass test or the touch test can easily determine it at home. Knowing your hair's porosity allows you to tailor your hair care routine accordingly. For example, low-porosity hair requires less protein, while medium-porosity hair needs a balanced amount. Highly porous, severely damaged hair benefits from a high protein intake. Understanding your hair's porosity enables you to effectively strengthen and repair it. It's key to healthy, radiant hair.
