If you've ever wondered why some products work beautifully for someone else but do absolutely nothing for your hair, the answer is almost always hair porosity. It's the most overlooked factor in natural hair care — and understanding it will change everything about how you approach your routine.
What Is Hair Porosity?
Hair porosity refers to your hair's ability to absorb and retain moisture. It is determined by the structure of the hair cuticle — the outermost protective layer of each strand, made up of overlapping scales similar to roof shingles. How open or closed those scales are determines your porosity level.
Porosity can be genetic, but it can also be altered by heat damage, chemical processing, environmental exposure, and the products you use. This is why understanding and protecting your porosity is an ongoing part of healthy hair care — not a one-time discovery.
How to Test Your Hair Porosity
The Float Test: Take a clean, product-free strand of hair and drop it into a glass of room-temperature water. Observe over 2–4 minutes.
- Floats — Low porosity
- Sinks slowly to the middle — Medium porosity
- Sinks quickly — High porosity
The Slip & Slide Test: Take a strand of hair and slide your fingers from tip to root. If it feels smooth, you likely have low porosity. If it feels rough or bumpy, you likely have high porosity.
The Spray Test: Spritz a small section of dry hair with water. If the water beads up and sits on top, you have low porosity. If it absorbs immediately, you have high porosity.
Low Porosity Hair
Low porosity hair has tightly closed cuticles that resist moisture absorption. The challenge is getting moisture in — not keeping it there. Once moisture penetrates, low porosity hair actually retains it well.
Common signs: Products sit on top of hair, hair takes long to get wet, buildup accumulates quickly, hair dries slowly.
What it needs: Lightweight water-based products, regular clarifying, heat during conditioning, humectants.

“I finally understand why nothing was working. My low porosity hair needed lightweight products and clarifying — not heavy butters. The OrganiGrow low porosity system is the first routine that has made a real difference.” — Verified Customer
Medium Porosity Hair
Medium porosity hair has a balanced cuticle structure that allows moisture to enter and be retained effectively. It is the most versatile porosity type, but it still requires consistent care to maintain its balance — especially as heat, color, and environmental stress can shift it toward high porosity over time.
Common signs: Hair absorbs and retains moisture well, styles hold, hair is generally manageable and healthy-looking.
What it needs: Balanced moisture and protein, regular deep conditioning, scalp nourishment, protective styling.

High Porosity Hair
High porosity hair has raised or damaged cuticles with gaps that allow moisture to enter quickly but escape just as fast. This results in chronic dryness, frizz, breakage, and difficulty retaining length. High porosity can be genetic or caused by heat damage, chemical processing, or hard water exposure.
Common signs: Hair absorbs water instantly, chronic frizz, dries out quickly after moisturizing, excessive tangling and breakage, color fades fast.
What it needs: Heavier sealants, protein to fill cuticle gaps, consistent deep conditioning, protection from environmental stressors.

Why Clean Ingredients Matter for Every Porosity Type
Regardless of your porosity type, toxic ingredients make every hair condition worse. Sulfates strip the cuticle further. Silicones create false moisture while blocking real hydration. Petrolatum and mineral oil trap buildup inside the hair shaft. Synthetic fragrance irritates the scalp and disrupts the follicle environment.
Every OrganiGrowHairCo product is formulated without these ingredients — because clean, porosity-matched care is the foundation of truly healthy hair.
