When it comes to choosing the right products and routines for your hair, understanding your hair type is only half the story. One often overlooked, but extremely crucial aspect is hair porosity. Knowing your hair's porosity can dramatically improve the way your hair responds to moisturizers, oils, and treatments. And the best part? You can find out your hair's porosity with a simple hair porosity test at home. You will also get some best products from Asra Derm to protect your hair.
In this blog, we’ll dive deep into what hair porosity is, how to test it, and what it means for your hair care routine. By the end, you'll be equipped to give your hair exactly what it needs.
What is Hair Porosity?
Hair porosity refers to your hair's ability to absorb and retain moisture. It’s largely determined by the state of your hair’s cuticle, the outermost layer that protects the inner layers. When the cuticle is tightly bound, moisture struggles to get in or out. When it's loose or damaged, moisture comes in easily but escapes just as fast.
Types of Hair Porosity
Understanding the different types of hair porosity is essential for building a hair care routine that truly works for you. Porosity refers to how well your hair can absorb and retain moisture, and it’s determined by the condition of the cuticle layer. Hair porosity generally falls into three categories: low, medium, and high. Each type has distinct traits and specific care needs.
1. Low Porosity Hair
Low porosity hair has a tightly bound cuticle layer that lies flat, making it difficult for moisture and products to penetrate the hair shaft. Because of this, it tends to resist water and may take longer to get fully wet or dry. While low porosity hair often looks shiny and healthy, it can also be prone to buildup because products tend to sit on the surface instead of being absorbed. People with low porosity hair often struggle with deep conditioning treatments, which may not penetrate the strands without heat.
Key Characteristics:
- Takes a long time to get wet and dry
- Products tend to build up on the hair rather than absorb
- Water beads up on the hair surface
- Resistant to chemical treatments like coloring or perming
- Often appears shiny and smooth
2. Medium Porosity Hair
Medium (or normal) porosity hair has a cuticle layer that is looser than low porosity but not overly raised. This balanced structure allows moisture to enter and be retained efficiently, making it the most manageable porosity type. Medium porosity hair generally requires less maintenance and responds well to most hair care products, coloring, and styling treatments. It retains style well and doesn’t suffer from dryness or frizz as easily as high porosity hair.
Key Characteristics:
- Easily absorbs and retains moisture
- Hair looks healthy, shiny, and feels soft
- Holds styles well without excessive product use
- Accepts coloring and chemical treatments with minimal damage
- Requires minimal maintenance for moisture balance
3. High Porosity Hair
High porosity hair has cuticles that are raised or even damaged, which allows moisture to enter the hair quickly, but it also escapes just as fast. This type of hair is often the result of chemical treatments, excessive heat styling, or environmental stress. High porosity hair tends to feel dry and rough, and it may look dull or frizzy. Because it loses moisture easily, it often requires richer, more intensive moisturizers and sealing techniques to lock hydration in.
Key Characteristics:
- Absorbs water and products quickly, but loses moisture fast
- Hair dries quickly after washing
- Feels dry, rough, or frizzy
- Prone to breakage, tangling, and split ends
- Reacts strongly to humidity and weather changes
Why Does Hair Porosity Matter?
You might be using the best shampoos, conditioners, and oils, but if they’re not suited for your hair’s porosity, you might not see results. Here’s why understanding porosity is a game-changer:
- Moisture retention: Knowing your porosity helps you understand how well your hair holds moisture.
- Product absorption: Some products work better for certain porosity types than others.
- Heat and chemical treatments: Your porosity level affects how your hair reacts to color, relaxers, or heat styling.
In short, porosity dictates your hair's behavior.
The Hair Porosity Test: How to Do It
Determining your hair porosity is the first step to building a hair care routine that truly works for you. The good news is that you don’t need any expensive tools or salon visits to figure it out, just a few strands of clean hair and a glass of water.
Float Test
This simple at-home method, known as the Float Test, can reveal whether your hair is low, medium, or high porosity in just a few minutes.
What You’ll Need:
- A clear glass or bowl filled with room temperature water
- A few clean strands of shed hair (from your brush or comb)
Note: Make sure the hair strands are free of any product, oil, or conditioner. Product buildup can interfere with the accuracy of the test.
Steps to Perform the Hair Porosity Test:
- Step 1: Shampoo your hair to remove oils, conditioners, or styling products. Let it air dry without adding anything to it.
- Step 2: Once dry, take 1–2 strands of naturally shed hair from your comb or brush.
- Step 3: Fill a glass with room temperature water (not hot or cold; extreme temperatures can skew results).
- Step 4: Gently drop the hair strands into the glass of water and observe them for about 2 to 4 minutes.
Interpreting the Results:
-
Hair Floats on Top = Low Porosity
Your hair’s cuticles are tightly sealed and resist moisture. Products may sit on the surface instead of penetrating. -
Hair Hovers in the Middle = Medium (Normal) Porosity
Your cuticle is slightly open, allowing moisture to enter and stay. Your hair absorbs and retains moisture well. -
Hair Sinks to the Bottom Quickly = High Porosity
Your cuticles are raised or damaged, so your hair soaks up moisture fast but also loses it just as quickly.
Tips for Accurate Results:
- Use freshly washed hair strands without any leave-in products or oils.
- Perform the test in a still environment, with no fans or air movement that might affect the water surface.
- For best results, test multiple strands from different parts of your head, as porosity can vary across sections.
The Slide Test (Strand Texture Test)
This test helps you assess the physical texture of your hair strand and how open or smooth your cuticle layer is.
How to Do It:
- Take a single, dry strand of hair from your head (or brush).
- Hold it at one end and gently slide your fingers upward, from the tip toward the scalp.
- Pay attention to how it feels under your fingers.
What You’ll Notice:
- Smooth glide: If your fingers slide up easily without friction, your hair cuticles are tightly sealed, this indicates low porosity.
- Slight bumpiness: If you feel some texture but nothing extreme, you likely have medium porosity.
- Rough or jagged feel: If it feels coarse or bumpy all the way up, it likely indicates high porosity, where the cuticles are lifted or damaged.
2. The Spray Test (Water Absorption Test)
This test mimics how your hair reacts when you apply water or liquid-based products.
How to Do It:
- Mist a small, clean section of dry hair with a spray bottle of room temperature water.
- Watch closely how the water behaves on your hair.
What You’ll Notice:
- Beads up and rolls off: Water just sits on the surface? That’s low porosity, your cuticle is too tight to let moisture in easily.
- Sits briefly, then absorbs: If it takes a few seconds to sink in, your hair is likely medium porosity.
- Absorbs instantly: If the water disappears almost as soon as you spray it, it’s probably high porosity, which means your cuticles are wide open.
3. The Drying Time Test
How quickly your hair dries after washing can reveal a lot about its porosity. This test works best on clean, product-free hair.
How to Do It:
- Wash your hair as usual using a sulfate-free shampoo and conditioner.
- Do not apply any styling products, leave-ins, or oils.
- Let your hair air dry naturally.
- Observe how long it takes to dry.
What You’ll Notice:
- Takes a long time to dry: You have low porosity hair. The cuticles resist water entry, but once wet, they trap moisture inside.
- Dries in a moderate, consistent way: You likely have medium porosity hair, ideal for moisture balance.
- Dries very fast: This is a sign of high porosity; the hair absorbs water quickly but loses it just as fast due to raised or damaged cuticles.
4. The Product Absorption Test
This test shows how your hair reacts to products, especially conditioners and oils.
How to Do It:
- Apply a small amount of leave-in conditioner or light oil to a clean, dry section of your hair.
- Observe how the product behaves over the next 10–15 minutes.
What You’ll Notice:
- Product just sits on top: Your hair isn’t absorbing it easily, this indicates low porosity.
- The product gradually sinks in and softens the hair: That’s a sign of medium porosity.
- Product gets absorbed immediately but hair still feels dry later: That’s typical of high porosity, where moisture enters fast but doesn’t stay in.
