Anti-humectants for high porosity hair

If you have particularly dry, parched hair, “humectant” is a magic word.

Humectants like aloe and honey are holy grail products for many high porosity ladies because of their hydrating properties and the extra shine they give the hair.

But when you live in a humid environment, these much-loved, cult-favorite humectants go from your hair’s best friend to its downfall in a snap.

Humectants and humidity don’t mix, and when you’re not smart with how you use your favorite glycerin or flaxseed products, you could end up with poofy hair.

Luckily, anti-humectants are around to save the day.

I’ll be going into detail about anti-humectants for high porosity hair.

What are anti-humectants?

To get a good grasp of anti-humectants, we need first to understand what humectants are.

We hear it a lot when we talk about hydration, from hyaluronic acid in skincare to aloe vera for the hair.

Other popular hair humectants include glycerin, sorbitol, honey, and flaxseed.

Humectants are excellent hydrators because they absorb moisture from the air and into the hair.

This is well and good for dehydrated locks, but if you live in a humid environment with lots of moisture in the air, the humectants’ absorption can quickly spiral out of control.

Too much moisture will force your hair cuticles to expand and swell, making your curls look poofy, frizzy, and devoid of any definition.

Anti-humectants are the complete opposite of that.

They’re moisturizers as well, but they seal in hydration and block excess water from being absorbed into the hair.

Because it closes up your hair shaft, it eliminates frizz, keeping the hair sleek and put together.

Some of the most popular anti-humectants come in the form of rich, nourishing oils, such as shea butter, beeswax, and coconut oil.

These fight frizz in hot, humid weather, and more importantly, they block moisture from escaping your porous hair.


What is high porosity hair?

High porosity hair means that your cuticles have spaces in between them, leaving your hair shaft full of gaps.

These gaps act like pores in a sponge – they allow easy entry of moisture and oils into the hair, but just as quickly releases them too, making it very hard for highly porous hair to retain moisture.

This kind of porosity in hair is more often than not a side effect of abusing your hair with frequent chemical processes like relaxers, bleach, and dyes.

Styling with hot tools regularly can also affect your hair porosity and lift your cuticles, making it more challenging for them to stay moisturized.

Simply put, high porosity hair needs a lot of moisture.

That’s why humectants are a godsend for porous hair.

But if you use and abuse humectants without understanding when you should switch things up to an anti-humectant instead, you’re just setting yourself up for failure.


At what point do you use anti-humectants on high porosity hair?

You should use an anti-humectant to keep your hair moisturized if you’re going to a humid area, or a place high in water vapor in the air.

You always have to anticipate how your highly porous hair will react to different weather.

Look out for cities with high dew points – that means it’s extra humid there.

You can use your trusty weather app on your phone to see what the dew points are in various areas.

If the dew point is anywhere from 35-50°F, it’s safe to use humectants.

But if the dew point is anywhere below that or goes up to around 60°F, you should be using anti-humectants because it’s either extremely dry (your hair will have nothing to absorb) or very humid (you risk over-moisturizing the hair).

A good rule of thumb to follow is to use anti-humectants in hot, sweaty weather and humectants for cool and dry places.

If you use anti-humectants in super cool and dry weather, you could leave your hair brittle and straw-like.

Use your anti-humectants at the end of your hair care routine.

Because it’s a sealant, it should be the last thing you massage into your hair so that all your hydrating, conditioning products stay locked in your tresses.


What types of anti-humectants are there?

Even if we don’t know it, many familiar everyday ingredients in our hair products are anti-humectants.

Anti-humectants for high porosity hair range from natural, organic oils and butters to science-based compounds and copolymers.

Let’s start with the ingredients that are au naturel.

Natural forms

Many of our favorite rich, thick, deeply nourishing hair oils are anti-humectants because they make great sealants.

These include coconut oil, olive oil, avocado oil, and shea butter.

High porosity hair generally loves these oils because of the moisturization, shine, and curl definition they provide; but they’re ten times more powerful and useful when they’re pit against humidity.

These oils are fantastic at fighting humidity because they produce a protective coating around the hair shaft, prohibiting any excess moisture from coming into the cuticle to make it expand and look poofy.

You can use these oils and butters in their pure form when finishing up your hair care routine before heading outside in the summertime.

But if you haven’t quite mastered the art of using oils on your hair, you can just watch out for those ingredients in finishing serums, moisturizing creams, and gels.


Other forms

Apart from these organic oils, there are also a bunch of anti-humectants that come in other forms.

These include polymers like silicones and esters, or more unique natural occlusives like beeswax or triglycerides from plants.

I know what you’re thinking.

Silicones are bad for the hair! Right?

Well, not exactly.

Silicones, like most polymers in hair products, actually do a great job sealing in moisture in the hair by creating a protective layer around the hair strand.

It also keeps your hair from frizzing up, especially when it’s hot and humid.

The issue with these non-oil forms of anti-humectants is that they may be too thick and weigh your hair down.

They could also build up on your scalp and hair, giving you a tough time washing them out unless you use a heavy-duty clarifying shampoo.

If you follow the Curly Girl Method and have vowed never to use silicones, don’t sweat it.

You can always opt for more natural anti-humectant ingredients, like olive and coconut oils or even beeswax.


Commercial anti-humectants for high porosity hair

If you’re uncomfortable using pure, rich oils on your hair, you can opt for thoughtfully designed hair care products that contain anti-humectants instead.
