Ever wonder why your hair drinks up some products but ignores others? It might have nothing to do with the product itself. The secret could be your hair’s porosity. Sounds technical, but it’s actually simple once you break it down. And once you understand it, moisturizing gets way easier.
Let’s walk through what hair porosity is, why it matters and how you can build a hydration routine that actually works for your strands. Beauty Market Online carries products made for every hair type, so once you know your porosity, finding what works gets a whole lot easier.
What Does Hair Porosity Even Mean?
Porosity is all about how your hair soaks in and holds moisture. That’s it. It depends on how open or closed your hair’s cuticle layer is. The cuticle is like a shingle roof covering each hair strand. The way those “shingles” sit determines how water, oils and products move in or out.
There are three basic types of porosity:
-
Low porosity means the cuticles are tightly packed. Water rolls right off. Products tend to sit on top.
-
Medium (or normal) porosity is the sweet spot. Moisture goes in and stays there. Styling is easier too.
-
High porosity means the cuticles are lifted or damaged. Moisture gets in fast but it escapes just as quick.
You don’t need a lab test to figure it out. A few simple signs can clue you in.
How Do You Know Your Hair’s Porosity?
Try the water test. Take a clean strand of dry hair and drop it into a glass of water.
-
If it floats on top you probably have low porosity hair.
-
If it sinks slowly to the middle that’s medium porosity.
-
If it drops fast to the bottom it’s likely high porosity.
There are other clues too.
Low porosity hair takes ages to dry. It resists products. You’ll notice a lot of buildup.
High porosity hair loves product but still feels dry. It may frizz easily. Breakage is common.
Medium porosity behaves pretty well most days and reacts fine to most routines.
Why Porosity Changes Everything About Moisturizing
You could be using the best conditioner money can buy, but if it’s wrong for your porosity, it won’t help. Moisturizing low porosity hair isn’t the same as moisturizing high porosity strands. Your approach has to change.
Let’s break it down.
Low Porosity Hair Needs Lightweight Moisture
Since the cuticle layer is so tight, you’ve got to find ways to open it up gently. Warm water helps. So does steam. Lightweight, water-based products work better than thick creams. Think aloe vera juice or leave-ins that don’t weigh the hair down. A good example is the Sobe Luxe Hair Volumizing Mousse. It’s super airy and adds volume without build-up which makes it ideal for low porosity hair that hates anything heavy.
Avoid heavy oils. They’ll just sit on top. Look for ingredients like glycerin, rose water, or panthenol. These can sneak past those tight cuticles and give your hair what it needs.
And go easy on protein. Too much makes low porosity hair stiff.
High Porosity Hair Needs Sealing Power
If your hair’s highly porous, moisture escapes fast. The goal here is to lock it in. Start with hydrating leave-ins or creams that pack in moisture. Then seal it with something heavier like shea butter or castor oil.
Best oils for porous hair tend to be thick ones. Jamaican black castor oil, avocado oil and argan oil work well. These create a barrier and help reduce how fast moisture disappears. If you’re going the argan route, Keragen Moroccan Argan Oil is a great pick. It’s lightweight enough to smooth frizz but rich enough to lock in moisture on high porosity strands. Just a few drops go a long way.
Also, this type of hair loves protein. It helps fill in the gaps along the hair shaft and adds strength. Look for products with keratin or silk proteins.
Medium Porosity Hair Just Needs Balance
Lucky you if you fall in this category. Moisturizing isn’t too hard. Stick to hydrating shampoos, light conditioners, and a basic oil or butter to seal. Don’t go overboard with protein or heavy oils.
Still, things can shift over time. Color treatments, heat styling, or even just weather changes can raise your porosity. So stay in tune with how your hair feels.
Can Hair Porosity Change Over Time?
Yes, it can.
Bleaching, coloring or flat ironing too often can lift those cuticles permanently. That turns medium or low porosity into high porosity. Even too much sun or swimming in chlorinated water can do it.
On the flip side, good habits can help restore some structure. Deep conditioning, trimming split ends and using heat protectants, all these things help protect the cuticle layer.
How to Build a Hydration Routine by Porosity
Once you know your type, your hair care gets simpler. Here’s how to think about it.
For Low Porosity Hair:
-
Always use warm water to wash.
-
Try steaming your hair before applying masks.
-
Use light, water-based leave-ins.
-
Skip heavy oils. Go for jojoba or grapeseed oil if needed.
-
Clarify once a month to prevent buildup.
For High Porosity Hair:
-
Use creamy, rich conditioners.
-
Layer products: moisture first, oil or butter second.
-
Try deep conditioning often.
-
Use protein-rich treatments regularly.
-
Avoid too much heat or chemical damage.
For Medium Porosity Hair:
-
Rotate between moisture and protein treatments.
-
Use a simple LOC method: Liquid, Oil, Cream.
-
Stick with mild shampoos and balanced conditioners.
-
Don’t overload on anything. Less is more here.
Conclusion
Moisturizing your hair isn’t one-size-fits-all. And porosity is the reason why. Once you figure out where you fall on the porosity scale, you can stop guessing. Your products start making sense. Your routine finally works.
Start small. Change one thing in your routine that matches your porosity. See how your hair responds. Soft, shiny, healthy hair isn’t about luck. It’s about learning your hair and giving it what it truly needs.
FAQs
1. Can I have different porosity levels in one head of hair?
Yes. Roots might be low porosity while ends (especially if color-treated) can be high porosity.
2. How often should I check my hair’s porosity?
Every few months or after any big change like coloring or heat styling. Your hair changes with your habits.
3. What’s the best oil for low porosity hair?
Light oils like jojoba, argan, or sweet almond oil absorb better and don’t weigh it down.
4. Is porosity the same as hair type?
Nope. Porosity is about how your hair handles moisture. Hair type is about curl pattern or texture.
5. Can high porosity hair become low again?
Not completely, but you can improve moisture retention with regular deep conditioning and damage control.
