Low-Porosity Hair Merchandise and Ideas

Past stating that their hair is “blonde,” “brief,” or “curly,” they’re going to most likely launch right into a monologue about their hair’s density, thickness, and elasticity.


They will probably additionally contact on their hair’s porosity, i.e. how simply it absorbs and retains water. Having low-porosity hair is a blessing and a curse: Strands retain water properly, however they do not simply take in water within the first place. If you happen to’re at present taking your personal deep dive into semi-niche hair subjects and are curious in regards to the ins and outs of low-porosity hair, this is a information to the subject from beauty chemist and educator Erica Douglas, aka Sister Scientist.



Q: I feel I’ve low-porosity hair as a result of I wrestle to maintain my hair moisturized. How can I discover the perfect low-porosity hair merchandise and what ought to my hair-care routine appear like?

A: Low-porosity hair thrives with a mix of steam remedies and light-weight, water-based merchandise, in response to Douglas. However earlier than you overhaul your routine, it is useful to grasp the distinction between low- vs. high-porosity hair, and tips on how to decide the place you fall on the porosity spectrum.



What Is Low-Porosity Hair?

As talked about, low-porosity hair would not simply absorb or lose moisture in comparison with high-porosity hair. The rationale why pertains to the anatomy of your hair. The outermost layer of a hair strand is known as the cuticle, and it is made up of scale-like buildings, which Douglas likens to shingles on a roof. These quote-unquote shingles “open and shut evenly, and that is what permits moisture to enter the hair,” she says.


In case you have low-porosity hair, you are working with a comparatively impervious roof that does not let in a lot water when it rains. “Low-porosity hair is hair the place the cuticle layer is extraordinarily dense and compact, and that makes it very exhausting for the hair to soak up water or moisture by means of that high layer of the hair,” says Douglas. “That is additionally why low-porosity hair is normally extraordinarily easy.”




Genetics play a job in your hair’s porosity, however low porosity can have an effect on the complete vary of straight to curly hair sorts, explains Douglas. “I’d say that there was some linkage between some ethnicities [and hair porosity] but it surely’s not a really hardcore correlation,” she says. “It is not 100% of the time. A whole lot of occasions, very straight hair tends to be decrease porosity historically, however that is not a truth.” In different phrases, it is doable to have low-porosity curls or straight hair that is porous.


Your hair’s porosity might be extra of a mirrored image of your styling habits. “I feel there’s extra correlation between the way you model your hair and your porosity than what your pure, organic disposition is to a sure porosity degree,” says Douglas. Styling remedies (together with everlasting hair colour, relaxers, and even styling merchandise) enhance the pH of hair, which causes the cuticle to open to an excessive diploma, growing hair’s porosity, she notes. And sizzling instruments can eat away on the cuticle layer over time, she provides. “As extra broken spots happen on that cuticle layer, you are principally creating extra entry factors for moisture.” So, in case you have low-porosity hair, there is a good likelihood you are taking a comparatively minimal method to styling.

Easy methods to Determine Out If You Have Low-Porosity Hair

Whereas it isn’t all the time 100% correct, the “float take a look at” is a reasonably dependable means to determine your hair’s porosity, says Douglas. To strive it, you may take a strand of your hair out of your comb, wash it with shampoo, enable it to dry, then place it in a glass of water. If it sinks to the underside of the glass instantly, you most likely have high-porosity hair, as Form beforehand reported. Medium-porosity hair will float for just a few seconds after which sink, whereas low-porosity hair will take even longer to sink to the underside. A cool trick: If you happen to lower the strand in half first, and the phase that was nearer to your scalp takes longer to sink, that is a sign that the ends of your hair have the next porosity than your roots, possible as a consequence of injury from styling, says Douglas.




That stated, in case you’re not up for any science experiments, you possibly can nonetheless get a way of your hair’s porosity. Take into consideration how your hair behaves while you bounce right into a pool or take a bathe. If it looks as if it takes some time in your hair to absorb the water, you most likely have low-porosity hair, says Douglas. Alternatively, in case your hair rapidly soaks up water and air dries very quickly, you possible have high-porosity hair.



Easy methods to Moisturize Low-Porosity Hair

At this level you are most likely questioning precisely tips on how to moisturize low-porosity hair, provided that water would not simply go by means of its cuticle layer. The bottom line is to make the most of steam, a clarifying shampoo, and light-weight merchandise.


On Wash Days

On wash days, steam is your pal, says Douglas. “Primarily, the dimensions of the water molecules in steam are a lot smaller than liquid molecules in water,” she explains. “As a result of the molecules in steam are a lot smaller, it is a lot simpler to penetrate the cuticle. The extra you possibly can penetrate that cuticle with moisture, it opens up these layers to obtain your conditioning remedies and to primarily pull in additional moisture.”


Spend 15 to twenty minutes treating your hair with steam earlier than washing, a step that is the “key to unlocking very dense, compact hair, which is low porosity hair,” says Douglas. If you happen to do not personal a steamer — a hair software designed for this very goal — you possibly can activate a sizzling bathe and shut the door of your rest room to steam up the room, she says.

Lastly, think about using a clarifying shampoo on a biweekly or month-to-month foundation, suggests Douglas. “It is so exhausting to get moisture into low-porosity hair. You wish to just remember to’re eradicating as a lot build-up from the hair as doable with a purpose to be certain that the hair is basically going to have the ability to take in and absorb no matter conditioning remedies you’re subjecting the hair to,” she says.




In Between Washes

As for selecting styling merchandise to make use of between washes, low-porosity hair tends to reply higher to water-based merchandise, says Douglas. If water is the primary ingredient on a product’s ingredient checklist, it is most likely a water-based product. That is a fast approach to inform that wherever from 50 “to 90 p.c of that formulation or that product is water,” she says. “Utilizing merchandise like that, particularly as your first step in your styling routine, actually helps to make sure that you are getting as a lot water as near the cuticle floor as doable.” Silicone- or oil-based merchandise usually tend to sit on high of fairly than take in into your hair.


Normally, you are higher off with light-weight merchandise. “Low-porosity hair shouldn’t be absorbing merchandise as quick as high-porosity hair absorbs the product, so loads of occasions you are going to get build-up sooner,” says Douglas. “Having the ability to prioritize water-based merchandise and use very skinny or thinner light-weight oils or silicones is a significantly better routine than utilizing the heavier oils and silicones with low-porosity hair.”


Whilst you can view low-porosity hair as an excellent factor — it is usually an indication you might have minimal injury — it presents its challenges. In case your hair would not precisely welcome moisture with open arms, alter your routine and discover appropriate light-weight hair merchandise that may work in your favor.
