Understanding your hair porosity is the key to achieving healthy, moisturized hair. Hair porosity refers to your hair's ability to absorb and retain moisture, and knowing your porosity type helps you choose the right products for optimal results.
What is Hair Porosity?
Hair porosity is determined by the condition of your hair's cuticle layer. The cuticle acts like shingles on a roof - when they're tightly closed, moisture has difficulty getting in and out. When they're raised or damaged, moisture flows freely.
The Three Types of Hair Porosity
Low Porosity Hair
Low porosity hair has tightly closed cuticles that resist moisture. This hair type often feels dry and takes forever to get wet in the shower. Products tend to sit on top rather than absorbing.
Best products for low porosity hair:
- Hair Dew Low Porosity Leave In - lightweight formula that penetrates easily
- Stimulating Scalp Beverage Low Porosity - promotes circulation for better absorption
- Re-DO PrePoo Low Porosity - preps hair for better product penetration
Medium Porosity Hair
Medium porosity hair has a balanced cuticle structure that allows moisture to enter and stay. This is often considered the ideal porosity type as it's easier to maintain.
Best products for medium porosity hair:
- Curling Custard Gel Low to Medium Porosity - perfect hold without buildup
- Stimulating Scalp Beverage Medium Porosity - balanced nourishment
High Porosity Hair
High porosity hair has raised or damaged cuticles that allow moisture to enter easily but also escape quickly. This hair often feels dry shortly after moisturizing and may be prone to frizz.
Best products for high porosity hair:
- Hair Dew Medium/High Porosity Leave In - seals in moisture
- Stimulating Scalp Beverage High Porosity - intensive nourishment
- Ultra Hydro Repair Hair Mask - weekly intensive treatment
How to Test Your Hair Porosity
The Float Test
Take a few strands of clean hair and place them in a glass of water. Low porosity hair will float, medium porosity will sink slowly, and high porosity will sink quickly.
The Slip and Slide Test
Run your fingers up a strand of hair from tip to root. If it feels smooth, you likely have low porosity. If you feel bumps or resistance, you have higher porosity.
Creating Your Porosity-Specific Routine
Once you know your porosity type, you can build a routine that works with your hair's natural characteristics rather than against them.
For all porosity types, we recommend:
- Starting with a gentle cleanser like GrowPoo Moisturizing Shampoo
- Following with a porosity-appropriate conditioner
- Using a leave-in treatment designed for your porosity level
- Sealing with a light oil or cream
Understanding your hair porosity is a game-changer for your hair care routine. When you choose products formulated for your specific porosity type, you'll see dramatic improvements in moisture retention, manageability, and overall hair health.
