Learning how to moisturize low porosity hair is not as complicated as weâve been led to believe.
Simply put, hereâs how to keep low porosity hair moisturized:
- Keep the hair clean and clarified, to allow moisture to enter your hair;
- Prioritize light-weight, water-based products over heavy oils and oil-based products to keep the hair hydrated for longer;
- Use ambient heat strategically to set the hair and help products penetrate;
- Employ natural hair friendly tools that will work with your coils, not against it, and;
- Set your hair before bed to protect your coils and retain your styles
- Letâs get into the details of what this looks like.
Letâs get into how to keep low porosity natural hair moisturized.
What Is Natural Hair Porosity
As a friendly reminder, hair porosity is important because it measures our hairâs ability to retain moisture.
In essence, it is the ability for our hair cuticles (which are much like the pores on our face) to open up and take in the water we are giving it.
There are, generally speaking, three types of hair porosity: low, medium, and high.
Natural Hair Porosity
Natural hair porosity is the ability of your hair to absorb water and/products.
Low porosity natural hair has a low absorption rate, because the cuticles are stubbornly closed. It is difficult for this hair porosity to absorb moisture.
High porosity natural hair has a high absorption rate, because the cuticles are always open. It is difficult for this hair porosity to retain moisture.
What Is Low Porosity
Specifically, low porosity hair is when your cuticles are tight and flat.
The cuticles are so tightly shut that moisture and products have difficulty penetrating into through the cuticles and into the hair.
In other words, low porosity hair has an incredibly with high product buildup potential.
If youâve ever asked why is low porosity hair always dry, this is why! Product buildup is a significant factor in why low porosity hair is dry.
In fact, many âlow porosityâ naturals can be medium-porosity but because of product buildup, theyâve reduced their porosity because of all the layers of buildup. Yikes!
Letâs get into the exact recipe to moisturizing low porosity hair.
How To Moisturize Low Porosity Hair
Shampoo is key
The science is clear: shampooing natural hair every 7-10 days is an absolute non-negotiable if you want to have healthy, hydrated and happy natural hair.
This is true for ALL naturals, but even more important in low porosity hair.
Remember: moisture cannot travel through layers and layers of dirt.
If you are not properly clarifying your low porosity hair, youâll continuously experience dry hair because your strands are not experiencing that moisture. Itâs just contributing to product buildup.
Donât buy into the notion that natural hair will dry out natural hair.
While itâs true that some shampoos can be drying, there are plenty that are not!
Pick yourself up a gentle, moisturizing shampoo you can use on a weekly basis, and once a month (or whenever you feel you need), use a deeper cleansing shampoo to detox the hair. Youâll find that your hair will be softer and more supple when you apply your leave-in products.
Redken All Soft Shampoo
Best for TYPE 3-4
This shampoo is a go-to for many licenced cosmetologists and stylists. Itâs salon quality and highly moisturizing, yet it will clarify your hair thoroughly to give a silky press. Double cleanse your hair and scalp, smoothing your strands down as you go, for best results.

Best for TYPE 3 – 4
This shampoo is incredibly gentle and non-stripping, but contains enough surfactants to thoroughly cleanse your hair and remove buildup. Ginger root oil â the second ingredient in the formula â is antiseptic, boosting overall scalp health. A must have shampoo in any high porosity natural hair routine!
Minimal oils
A common question in the natural hair community is: should I use oils?
The answer: it depends.
Weâve already established that low porosity naturals experience dryness and product buildup much more often than other porosity types.
Oils, while they are packed with vitamins and fatty acids, have zero water content.
Using them in your leave-in routine may not give you an optimal style because itâs water that defines our curls and coils and gives our natural hair styles that full, plump look.
Itâs best to use water and water-based products in your leave-in and styling routine.
If you want to use oils, use them as a hot oil prewash treatment before your shampoo days. Just be sure to properly shampoo your hair to get all the oil out and avoid more buildup.
Water over everything
On that note, water should be considered your best friend if you have low porosity natural hair.
Water is natureâs only true moisturizer. That means, applying your leave-in stylers on damp hair and using water-based, light-weight products.
This will ensure that your low porosity hair will remain hydrated until the next wash day.

Best for TYPE 3-4, low porosity
This light-weight formula is perfect for low porosity naturals looking for moisture without the product buildup. It adds definition while replenishing moisture to curls and coils, resulting in soft, supple and defined hair.
On damp, sectioned hair, section off your hair and apply a light amount of a lightweight leave-in conditioner. Keep applying water to make sure the leave-in is fully mobile and melts into the hair.
Follow this up with a styler of choice: gel for wash and go, and mousse for twist-outs/braid-outs. Again, keep adding water to each section to work the product into your hair.
Ambient heat â How to dry low natural hair
Heat gets a bad rep in the natural hair community.
Direct heat in the form of flat irons can damage your cuticle layer if done excessively.
To truly dry low porosity hair, itâs optimal to use ambient heat, or indirect heat in the form of hooded dryers or diffusers, are highly effective in setting low porosity hair styles.
Once youâve applied your products on wet hair, instead of allowing your hair to air dry, sit under a hooded dryer or use a blow dryer with diffuser attachment (using the lowest warm setting) and allow your style to set.
An issue with low porosity hair is that products sit atop the hair and doesnât do its job.
Setting your styles with heat will help with this!
Using ambient heat when drying the hair, will set your styles better and reduce breakage in the long-run. Youâll find that your hair will retain moisture much longer!

Use protein strategically
Our hair is made out of a protein called keratin, a heavily-bonded protein that keeps our curls bouncy and elastic.
Protein treatments not only work to keep our moisture-protein balance aligned, but they also fill in cracks and holes in the surface of our cuticle layer.
However, too much protein treatments can result in protein overload, and this is detrimental to low porosity hair which is already dealing with dryness.
To mitigate this, look for treatments that:
- Contain protein-free products, including your leave-in conditioners
- Do occasional protein treatments using small-sized protein molecules such as amino acids, which that are small enough to enter the cuticle and fortify your cortex without causing dryness.

How do you keep low porosity hair moisturized (until the next wash day)
Sleep with silk
Sleeping with cotton is a sure way to dry out your low porosity hair.
Cotton not only absorbs moisture from the hair, but its fibres tug at our cuticle layer, frizzing out our styles and further accelerating dryness.
Silk is the best option to sleep with natural hair. It will not cause dryness and the smooth, silky fibres will not tug on your hair.

Keep your fingers out of your hair
That habit where you pick at your hair excessively?
Yeah, stop that.
Similar to cotton, your fingers can rob your hair of its precious moisture, and it can also frizz up your styles.
Try to keep your hands out of your hair as much as you can. If you want to fluff out your hair, use an afro pick!
How often should you moisturize your low porosity hair
If youâve ever asked the question, how often should you moisturize your low porosity hair, this part is for you.
The answer: whenever your hair feels dry.
If youâve done the above correctly, your hair should remain moisturized for at least 4-7 days.
When you feel like your hair is dry for your standards (i.e. it isnât holding any definition, feels dry, looks pale, etc.), itâs time to re-moisturize.
To re-moisturize natural hair is as simple as having a wash day, because moisture cannot penetrate through pre-existing product.
However, if you donât have time for this, re-purpose your style by sectioning your hair, spritzing some water on each section, and twist. You donât need to use product because there is product already on your hair.
Use ambient heat (via hooded dryer or blow dryer + diffuser) to set it. This will hold you over until your next wash day.

How to moisturize low porosity hair daily
If youâre looking to know how to moisturize low porosity hair daily, or how to moisturize low porosity hair between washes, the simple answer is: you shouldnât have to.
If you set your hair properly with the ambient heat tool of your choice, youâll find that you donât need to moisturize your daily.
However if your hair feels dry, section your hair, spritz some water on each section, and twist. You donât need to use product because there is product already on your hair. Be sure to set the style with ambient heat!
