Have you ever wondered why some hair products seem to sit on top of your strands while others are absorbed instantly? The secret often lies in your hair’s porosity. Hair porosity refers to your hair’s ability to absorb and hold onto moisture. Knowing your porosity level is like having a roadmap for your hair care routine, guiding you to the right products and techniques for healthy, hydrated hair.
The Simple Float Test for Hair Porosity
One of the easiest ways to check your hair’s porosity at home is the float test. Start with a clean strand of hair—you can collect one from your hairbrush or gently pluck one after washing. Drop the single strand into a glass of room-temperature water. Let it sit for a few minutes and observe where it settles.
What Your Test Results Mean
If your hair strand floats at the top for several minutes, you likely have low porosity hair. This means your hair cuticles are tightly closed, making it difficult for moisture to get in. If the strand sinks slowly to the middle of the glass, you probably have medium or normal porosity hair. This hair type has a balanced ability to absorb and retain moisture. If the hair sinks quickly to the bottom, you have high porosity hair. This indicates that the cuticles are more open or damaged, allowing moisture in easily but also letting it escape just as fast.
Caring for Your Specific Porosity Type
Understanding your result helps you customize your care. For low porosity hair, use light liquid-based products and apply heat with a warm towel or dryer cap to help open the cuticles and let moisture in. For normal porosity, a balanced routine with regular deep conditioning is usually sufficient. If you have high porosity hair, focus on sealing in moisture with heavier creams and butters, and incorporate protein treatments occasionally to help fill in gaps in the hair shaft.
Taking a few minutes to test your hair’s porosity can completely change your approach to hair care. It empowers you to choose products that truly work with your hair’s natural structure, leading to better hydration, less breakage, and more manageable strands every day.
