If you've ever felt like your hair care routine just isn't working — products sitting on top of your hair, moisture disappearing within hours, or your hair feeling perpetually dry no matter what you do — your hair porosity is almost certainly the missing piece of the puzzle.
Low porosity and high porosity hair are not just different — they are opposites. What works beautifully for one can actively damage the other. Understanding which one you have is the single most important step you can take for your hair health.
How to Test Your Hair Porosity
Before spending another dollar on products, take 60 seconds to test your porosity.
The Float Test: Take a clean, product-free strand of hair and drop it into a glass of room-temperature water. Watch what happens over the next 2–4 minutes.
- Floats at the top — Low porosity. Your cuticles are tightly closed and resistant to moisture.
- Sinks slowly to the middle — Medium porosity. Your cuticles are balanced and absorb moisture well.
- Sinks quickly to the bottom — High porosity. Your cuticles are raised or damaged and absorb moisture rapidly but lose it just as fast.
Low Porosity Hair: The Signs & What It Needs
Low porosity hair has tightly packed, flat cuticles that resist moisture absorption. The challenge isn't that your hair can't hold moisture — it's that moisture struggles to get in in the first place.
Signs you have low porosity hair:
- Products sit on top of your hair and never seem to absorb
- Hair takes a long time to get fully wet in the shower
- Hair dries slowly after washing
- Buildup accumulates quickly even with minimal product use
- Hair feels moisturized right after washing but dries out quickly
What low porosity hair needs: Lightweight, water-based products. Clarifying washes to prevent buildup. Heat during conditioning to help open the cuticle. Humectants to draw moisture in.

High Porosity Hair: The Signs & What It Needs
High porosity hair has raised or damaged cuticles with gaps along the hair shaft. Moisture enters easily — but escapes just as fast. This leads to chronic dryness, frizz, tangles, and breakage despite constant moisturizing efforts.
Signs you have high porosity hair:
- Hair absorbs water and products immediately but dries out within hours
- Chronic frizz, especially in humidity
- Hair feels dry and rough to the touch even after moisturizing
- Excessive tangling and breakage
- Color fades very quickly after dyeing
- Hair gets wet instantly in the shower
What high porosity hair needs: Heavier creams and butters to seal moisture in. Protein treatments to fill cuticle gaps. Consistent deep conditioning. Protection from heat and environmental damage.

The Key Difference at a Glance
Low porosity: Moisture struggles to get IN. Use lightweight products, clarify regularly, apply heat during conditioning.
High porosity: Moisture gets in easily but escapes fast. Use heavier sealants, protein treatments, and protective techniques to keep moisture IN.
Both porosity types thrive with clean, non-toxic ingredients — because buildup and harsh chemicals make both conditions worse, not better.
