How the Hair Porosity Test Works
From five questions to a suggested porosity level — here's what happens behind the scenes.
Answer 5 quick questions
How your hair reacts to the float test, water misting, air-drying time, product absorption, and your heat/chemical treatment history — the core signals used to estimate porosity.
Scored across all 3 levels
Each answer carries weighted points toward one or more porosity levels at once. Your five answers are combined into a running score for low, medium, and high porosity simultaneously.
See your suggested level
The highest-scoring level is shown first. A close second is surfaced if two levels score nearly equally, since porosity can vary across different parts of the same head.
Get matching care tips
Your result comes with practical care guidance suited to that porosity level — or try the float test yourself for the clearest physical confirmation.
The 3 Hair Porosity Levels
Your result will be one of these three porosity levels — a standard haircare framework based on how your cuticle handles moisture.
Low porosity hair has a tightly packed cuticle layer that makes it harder for moisture to get in — and once it does, harder for it to escape. Water tends to bead up on the hair surface rather than absorbing quickly.
Medium (sometimes called "normal") porosity hair has a cuticle layer that is looser than low porosity but not raised like high porosity — moisture moves in and out at a balanced rate. This is often considered the easiest porosity type to manage.
High porosity hair has a cuticle layer that is raised, gapped, or damaged — often from chemical processing, heat styling, or general wear — which lets moisture in quickly but also lets it escape quickly. This often leads to dryness and frizz.
How to Get an Accurate Result
Hair porosity can be tricky to judge day-to-day. These tips help your answers — and any follow-up float test — reflect your true porosity.
Try the float test for confirmation
Drop a clean, product-free strand of hair into a glass of room-temperature water and watch for a few minutes — floats (low), middle (medium), sinks (high). It's the most direct physical signal and a good complement to this quiz.
It's fine to have mixed porosity
Porosity can vary across your head — often higher at the ends (older, more weathered hair) and lower near the roots. Answer based on your hair overall, or focus on the section you care most about styling.
Answer based on clean, product-free hair
Styling products and buildup can mask your hair's natural reaction to water. Think about freshly washed hair with nothing applied when answering.
Retake it if your routine changes
Porosity can shift over time with heat styling, coloring, or chemical treatments. If your hair care routine or treatment history changes significantly, it's worth retaking the test.
Frequently Asked Questions
How accurate is this hair porosity test?
This is a simplified 5-question indicator based on your own observations, not a lab measurement. It scores your answers against all 3 porosity levels and surfaces the closest match — plus a close second when your answers land near the border of two levels. For the clearest physical confirmation, try the float test directly with a clean strand of your hair.
What is hair porosity?
Hair porosity describes how easily your hair's cuticle layer lets moisture in and out. Low porosity hair has a tightly packed cuticle that resists moisture; high porosity hair has a raised or damaged cuticle that absorbs and loses moisture quickly; medium (normal) porosity sits in between and is generally easiest to manage.
What is the float test for hair porosity?
The float test is a simple at-home check: drop a clean, product-free strand of hair into a glass of room-temperature water and watch what happens after a few minutes. Hair that floats on the surface suggests low porosity, hair that floats in the middle suggests medium porosity, and hair that sinks suggests high porosity.
Can my hair porosity change over time?
Yes. Heat styling, chemical treatments (coloring, relaxing, perming), and general wear can raise the cuticle and increase porosity over time, especially toward the ends of the hair. Reducing heat and chemical damage can help, though reversing porosity entirely is difficult once the cuticle is significantly altered.
Do I need a photo to take this quiz?
No. This is a question-based quiz — you answer 5 questions about how your hair reacts to water and products, and get an instant result. Nothing is uploaded, and it runs entirely in your browser.
Is this quiz free?
Yes, completely free with no sign-up, account, or payment required. You can take it as many times as you like.
What's the difference between hair porosity and hair type?
Hair type (straight, wavy, curly, coily) describes the shape or curl pattern of your hair strand. Hair porosity describes how well your hair absorbs and retains moisture, which is a separate property — two people with the same curl pattern can have very different porosity, and vice versa. Try our Hair Type Finder for your curl pattern separately.
