Curly Hair Porosity 101: What It Is & The Best Products for Each Type
If you have curly hair, you already know—it’s a world of its own! But did you know that understanding your hair’s porosity can completely change your hair care game?
Your hair’s porosity determines how well it absorbs and retains moisture. Whether your curls soak up product like a sponge or let water roll right off, knowing your porosity will help you choose the right products (and avoid frustration).
Let’s break it down so you can give your curls exactly what they need!
What is Hair Porosity?
Hair porosity refers to how open or closed your hair cuticles are, which affects how well moisture and products penetrate your strands.
There are three types of porosity:
- Low Porosity – Cuticles are tightly closed, making it hard for moisture to enter.
- Medium (Normal) Porosity – Cuticles are slightly open, allowing moisture to flow in and out easily.
- High Porosity – Cuticles are widely open or damaged, causing hair to absorb moisture quickly but lose it just as fast.
How to Test Your Hair Porosity
Not sure what your porosity type is? Try the Water Test:
- Take a clean strand of hair and drop it into a glass of water.
- Watch what happens:
- Floats on top? → Low porosity
- Sinks slowly? → Medium porosity
- Sinks quickly? → High porosity
Now that you know your type, let’s dive into the best hair care routine and products for each!
Low Porosity Hair: Hard to Absorb Moisture
💡 Signs of Low Porosity Hair:
✔️ Water and products sit on top of your hair
✔️ Takes a long time to dry
✔️ Prone to product buildup
How to Care for Low Porosity Hair
Your cuticles are tight, so moisture struggles to get in. The key is using lightweight, hydrating products and avoiding heavy oils and butters.
🛍 Best Products for Low Porosity Hair:
✔️ Clarifying Shampoo: Buildup is your enemy, so a gentle clarifying shampoo like OUAI Detox Shampoo removes residue without stripping moisture.
✔️ Lightweight Leave-In Conditioner: Try Kinky Curly Knot Today for hydration that won’t weigh your curls down.
✔️ Water-Based Moisturizers: Look for products with aloe vera, glycerin, or honey like Camille Rose Curl Love Moisture Milk.
✔️ Heat Activation: Use a steamer or a heated cap to open up your cuticles so products penetrate better.
Medium Porosity Hair: The Perfect Balance
💡 Signs of Medium Porosity Hair:
✔️ Absorbs and retains moisture well
✔️ Holds styles for a long time
✔️ Low maintenance
How to Care for Medium Porosity Hair
You’re blessed with a balanced porosity, meaning you don’t have to fight too hard to keep moisture in. Just focus on maintaining your hair health!

💡 Signs of High Porosity Hair:
✔️ Hair dries very quickly after washing
✔️ Often feels dry, brittle, or frizzy
✔️ Prone to breakage and tangles
How to Care for High Porosity Hair
Your goal is to seal in moisture and protect your cuticles. Look for rich, nourishing products and avoid harsh chemicals.
