Hair porosity is one of those terms that gets thrown around in the hair care world like it’s some secret code—but it’s actually the key to understanding why your hair behaves the way it does.
Too porous, and your strands guzzle up moisture and then leak it out like a broken faucet.
Not porous enough?
Your hair repels hydration like it’s allergic to it. But medium porosity hair is the sweet spot.
Unlike high or low porosity hair, medium porosity hair is the middle ground—it absorbs moisture just right, retains it long enough, and cooperates with most products. It’s the type that doesn’t leave you in a constant battle between dryness and oiliness.
Sounds like the dream, right? Not so fast.
Even medium porosity hair needs the right care to maintain that balance—otherwise, it can quickly tip into a state of chaos.
If your hair sometimes reacts well to deep conditioning but doesn’t need it constantly, holds styles without much fuss, and dries at a reasonable pace, you’re likely dealing with medium porosity hair. But guessing won’t get you anywhere—knowing for sure and caring for it correctly will make all the difference.
Let’s break it down—how to identify medium porosity hair, how to care for it, and what NOT to do if you want to keep it in top shape.
What is Medium Porosity Hair?
Medium porosity hair is the sweet spot of hair porosity types—it absorbs moisture without hoarding it and holds onto hydration without letting it escape too soon. Unlike low porosity hair, which resists moisture like a waterproof jacket, or high porosity hair, which drinks up hydration but leaks it out just as fast, medium porosity hair has cuticles that are slightly raised—just enough to let moisture in and keep it balanced.
Your hair isn’t completely immune to bad product choices. The wrong medium porosity hair regimen can tip it into grease overload or bone-dry disaster mode.
Too much moisture? Limp, lifeless strands.
Too little? Brittle, dry hair begging for hydration.
The trick is keeping your hair’s natural balance intact. Nail the right routine, and your hair will reward you with manageable, frizz-free, and effortlessly healthy strands.
How to Identify Medium Porosity Hair?
Not all hair drinks up moisture the same way. Some hair types hoard hydration, while others let it slip away like a leaky faucet. Medium porosity hair absorbs just enough moisture to stay hydrated but doesn’t drown in it. But how do you know if you have it?
1. The Medium Porosity Hair Porosity Test: Quick and Easy
Try this:
-
Spray Test: Spritz water on a section of dry hair. If it sits on top for too long, you likely have low porosity hair if it absorbs instantly, high porosity hair. But if it soaks in at a moderate pace, bingo—you’re medium porosity.
-
Float Test: Drop a clean strand of hair into a glass of water. If it floats, low porosity. If it sinks right away, high porosity. If it hovers somewhere in the middle? Congratulations, you’re in the medium porosity club.
2. Your Hair Absorbs Water, But Doesn’t Stay Wet Forever
Medium porosity hair takes in moisture efficiently but doesn’t hold onto it for an eternity. It dries at a moderate rate—not within minutes, but not hours either. If your wash days don’t feel like a waiting game, that’s a big sign.
3. It Holds Styles Well Without Being Fussy
Your hair isn’t a diva—it takes styling products well but doesn’t demand an entire chemist’s lab to behave. Curl creams, mousses, and gels do their job without overloading your strands, and heat styling isn’t a total disaster.
4. Balanced Moisture—Not Too Greasy, Not Too Dry
Somewhere between “I need deep conditioner every day” and “My hair hates products” is medium porosity hair. It retains moisture without turning into an oil slick or a dry mess.
If you’re nodding along to most of these, congrats—you’ve got the most manageable porosity type. But even hair that behaves well needs the right care.
How to Care for Medium Porosity Hair?
Your medium porosity hair care routine is about keeping things running smoothly. Your cuticles are naturally balanced, allowing moisture in and holding onto it without much drama. But that doesn’t mean you can slap on any product and expect perfect hair. The key is, give your hair what it needs—without overdoing it.
Here’s how to keep medium porosity hair in its prime—strong, hydrated, and thriving.
1. Use Gentle Shampoos and Conditioners
Medium porosity hair is a little picky about buildup. Harsh shampoos can strip too much moisture, but skipping washes altogether? That’s a one-way ticket to greasy, weighed-down strands. The sweet spot is using a gentle, sulfate-free shampoo that cleans without throwing your moisture balance into chaos.
✔ Use a moisturizing shampoo for regular washes—keeps hydration levels steady.
✔ Rotate with a clarifying shampoo when needed—removes buildup without over-drying.
✔ Pair with a lightweight conditioner—enough moisture without suffocating your strands.
Your hair wants to be cleaned, but not squeaky clean. Give it what it needs—not too much, not too little.
2. Deep Conditioning—The “Less is More” Rule
Deep conditioning is great—until it isn’t. Overdo it, and your hair turns into a flat, over-moisturized mess. Medium porosity hair thrives on balance, so bi-weekly deep conditioning is all you need to keep elasticity in check and hydration locked in.
✔ Pick a conditioner with a protein-moisture balance—hair loves variety.
✔ Avoid constant heavy treatments—your strands don’t need coddling.
✔ Listen to your hair—if it starts feeling limp, dial it back.
Deep conditioning is like dessert—great in moderation, but overdoing it ruins the whole meal.
3. Heat Styling: Tread Lightly
Your hair isn’t fragile, but that doesn’t mean it loves being fried with heat. Flat irons, curling wands, and blow dryers on full blast can weaken the cuticle over time, pushing your hair into high porosity territory (and that’s a mess you don’t want).
✔ Always use a heat protectant—non-negotiable.
✔ Lower the heat setting—you don’t need 400°F to curl a strand.
✔ Take breaks from hot tools—if your hair feels drier than usual, listen to it.
Too much heat turns healthy hair into a high-porosity nightmare. Protect your cuticle from heat damage, or regret it later.
4. Feed Your Hair from the Inside
Great hair isn’t just about products—it’s about what you eat, too. A balanced diet packed with proteins, healthy fats, and hydration keeps your hair strong, prevents breakage, and supports new growth.
✔ Protein: Your hair is literally made of it—don’t skimp.
✔ Omega-3s: Found in fish, nuts, and avocados—keeps strands soft and healthy.
✔ Water: Dehydration shows up first in your hair—so drink up.
Your hair is built from the inside out. Treat it well, and it’ll show.
Conclusion
Medium porosity hair maintenance is all about balance—too much moisture, and it gets limp; too little, and it starts acting out. Unlike high or low porosity hair, it plays well with most products, but that doesn’t mean you can neglect it. The right shampoo keeps buildup at bay without stripping moisture, deep conditioning works best in moderation, and excessive heat styling is an easy way to sabotage healthy cuticles. Even diet plays a role—because hair thrives when it’s supported from the inside out.
Keep your routine balanced, and medium porosity hair will reward you with fewer bad hair days and more effortless, healthy strands.
