Understanding your hair porosity is the single most important step in building an effective natural hair care routine. Porosity determines how your hair absorbs and retains moisture, which products work best, and what techniques will give you the healthiest results.
What Is Hair Porosity
Hair porosity refers to your hair's ability to absorb and hold moisture. It's determined by the condition of your hair's cuticle layer—the outermost protective layer made of overlapping scales. When these scales are tightly closed, moisture has difficulty penetrating. When they're raised or damaged, moisture enters easily but also escapes quickly.
There are three porosity levels: low, medium (normal), and high. Each requires a different approach to achieve optimal hair health.
Low Porosity Hair: The Moisture-Resistant Type
Characteristics:
Low porosity hair has tightly closed cuticles that resist moisture absorption. Water beads up on the surface rather than being absorbed quickly. Products tend to sit on top of the hair instead of penetrating, and it takes forever to dry once wet.
Common Challenges:
- Product buildup
- Difficulty absorbing moisture
- Takes hours to air dry
- Protein-sensitive (protein can make hair feel stiff)
- Heat styling required for deep conditioning
Best Products for Low Porosity Hair:
☐ Hair Dew - Low Porosity Leave In - Lightweight formula designed to penetrate resistant cuticles
☐ Re-DO PrePoo Low Porosity - Pre-shampoo treatment that opens cuticles for better moisture absorption
☐ Stimulating Scalp Beverage LOW POROSITY - Lightweight oil blend that won't cause buildup
☐ GrowPoo Clarifying Shampoo - Essential for removing buildup that low porosity hair attracts
☐ Curling Custard Gel Low to Medium Porosity - Defines curls without weighing hair down
High Porosity Hair: The Moisture-Hungry Type
Characteristics:
High porosity hair has raised or damaged cuticles with gaps and holes. It absorbs moisture quickly but loses it just as fast. Hair may feel dry shortly after moisturizing, tangles easily, and is prone to frizz and breakage.
Common Challenges:
- Loses moisture quickly
- Prone to frizz and tangles
- Breaks easily
- Dries very quickly
- Needs protein to fill gaps in cuticle
- Requires heavier products to seal moisture
Best Products for High Porosity Hair:
☐ Hair Dew – Medium/High Porosity Leave In - Rich, moisturizing formula that penetrates and seals
☐ Re-DO PrePoo Medium/High Porosity - Intensive pre-treatment that fills cuticle gaps
☐ Stimulating Scalp Beverage – High with Black Seed Oil - Heavier oil blend for maximum moisture retention
☐ Ultra Hydro Repair Hair Mask - Deep conditioning treatment for intensive moisture
☐ Vegan GroGurt with Chebe and Black Seed Oil - Protein treatment to strengthen and fill cuticle gaps
☐ Curling Custard Gel Medium to High Porosity - Heavier hold that locks in moisture
Medium Porosity Hair: The Balanced Type
Characteristics:
Medium porosity hair has slightly raised cuticles that allow moisture to enter and stay balanced. This is the easiest hair type to maintain and requires the least specialized care.
Best Products for Medium Porosity Hair:
☐ Stimulating Scalp Beverage - Medium Porosity - Balanced oil blend for healthy scalp and hair
☐ GrowPoo Moisturizing Shampoo - Gentle cleansing without stripping
☐ The Condish (Protein Free Conditioner) - Lightweight moisture for balanced hair
How to Test Your Hair Porosity
The Float Test:
Take a few clean strands of hair (product-free) and place them in a glass of room temperature water. Wait 2-4 minutes and observe:
- Floats on top = Low porosity
- Floats in the middle = Medium porosity
- Sinks to the bottom = High porosity
The Slip and Slide Test:
Take a strand of hair and slide your fingers up the shaft from tip to root. If it feels:
- Smooth = Low porosity
- Slightly textured = Medium porosity
- Rough or bumpy = High porosity
The Spray Bottle Test:
Spray a section of clean, dry hair with water and observe:
- Water beads up on the surface = Low porosity
- Water absorbs slowly = Medium porosity
- Water absorbs immediately = High porosity
Real Results from Real Customers
"I struggled with my low porosity hair for years until I switched to the Low Porosity Leave-In and PrePoo. Within 3 weeks, my hair was finally absorbing moisture. No more product buildup or crunchy hair!" - Destiny L.
"My high porosity hair was breaking constantly. After 8 weeks of using the High Porosity Scalp Beverage and GroGurt protein treatment weekly, my hair is stronger than it's ever been. I'm finally retaining length." - Shanice K.
"Understanding my medium porosity hair changed everything. I stopped over-complicating my routine and focused on balance. My hair has never looked healthier or grown faster." - Amber T.
Porosity-Specific Hair Care Routines
Low Porosity Routine:
1. Clarify weekly with GrowPoo Clarifying Shampoo
2. Apply Re-DO PrePoo Low Porosity before shampooing
3. Deep condition with heat (hooded dryer or steamer)
4. Use lightweight leave-ins and oils
5. Avoid heavy butters and proteins
6. Use warm water to open cuticles during washing
High Porosity Routine:
1. Moisturize daily with water-based leave-in
2. Apply Re-DO PrePoo High Porosity before every wash
3. Deep condition weekly with Ultra Hydro Repair Hair Mask
4. Protein treatment bi-weekly with GroGurt
5. Seal with heavier oils and butters
6. Use cool water rinses to close cuticles
7. Sleep with satin bonnet to retain moisture
Medium Porosity Routine:
1. Shampoo as needed (1-2 times per week)
2. Deep condition bi-weekly
3. Alternate between moisture and protein treatments
4. Use balanced products (not too heavy, not too light)
5. Maintain consistent routine for best results
Can Porosity Change
Yes. While your natural porosity is genetic, chemical treatments, heat damage, environmental factors, and aging can increase porosity over time. Low porosity hair can become high porosity through damage, but high porosity hair cannot become low porosity without new growth.
This is why protective styling, gentle handling, and porosity-appropriate products are essential for maintaining healthy hair.
The Bottom Line
Your hair porosity is not a limitation—it's a roadmap. When you understand whether your hair is low, medium, or high porosity, you can choose products and techniques that work with your hair's natural structure instead of against it.
Stop guessing and start seeing results. Test your porosity, choose the right products for your hair type, and watch your hair transform.
