Hair Porosity Test
Explore whether your everyday observations lean toward lower, medium or higher porosity. Answer four questions about your hair rather than relying on one floating strand. You will see what contributed to the result and what to watch for on your next wash day.

How to use the hair porosity test
- 1Think about clean hair and your usual routine, not a day with unusually heavy product buildup.
- 2Describe how it wets, how products feel and how long the conditioned feel lasts. Choose unsure whenever needed.
- 3Review the tendency and its limits. Repeat observations over several washes before changing your routine.
Method & limitations
Wetting behavior, product feel and moisture behavior each contribute a low (0), middle (1) or high (2) observation. We average answered observations; below 0.67 suggests lower porosity, above 1.33 suggests higher, and the middle suggests medium. Conflicting low and high observations produce a mixed result. Processing history adds context, not a score. At least two answered observations are needed. This heuristic does not measure cuticle structure or diagnose damage.

What porosity means for hair
Porosity describes how readily hair takes up and retains moisture. Lower and higher porosity are descriptions, not ratings of better or worse hair. Natural structure and a history of chemical or heat exposure can affect behavior. It is possible for the roots and older ends to respond differently, which is one reason a single quiz result should stay flexible.
Why a home observation has limits
Density, strand thickness, humidity and styling products influence drying and wetting. A float test also depends on the condition of the strand and water surface, so this tool does not treat sinking or floating as proof. Notice the pattern across several ordinary wash days. If your answers conflict, the result deliberately asks for more observations rather than presenting a precise laboratory classification.
Use your result as a small experiment
Keep a short record of one product amount or application change at a time. Compare how easily your hair detangles and how it feels once dry. A lightweight application may help you avoid heavy residue; a different conditioning approach may improve manageability. Stop changes that feel uncomfortable. This quiz does not prescribe treatments or identify scalp conditions.
Common questions
Is a water float test enough to know my porosity?
This tool does not use a float result as proof. Surface conditions and products can affect that observation. Several consistent observations are more useful for routine planning, and even those remain approximate.
What if I answer unsure?
Unsure answers are not scored as medium. With fewer than two usable observations you will get a request to observe more, not an invented porosity label.
Can different parts of my hair have different porosity?
Your roots and ends may behave differently, particularly after processing. You can run the quiz for each area and keep separate notes.
