We’ve all been there. We’re ten minutes into a looooong, blissful soak, the water is perfectly warm, and our stress is finally starting to dissolve. Then the question hits: what do we do with our hair? We know magnesium is a powerhouse for our muscles and our nervous systems, but is dunking our strands into the tub a genius beauty hack or a recipe for a bad hair day?
When we use Flewd Stresscare soaks, we’re dealing with high-quality magnesium chloride, which is a bit different from the standard Epsom salts we might find at the grocery store. While the minerals are busy replenishing our bodies, our hair is also soaking up that environment. Some of us swear by the volume and scalp-clearing benefits, while others worry about ending up with hair that feels like a bale of hay.
The short answer is yes, we can absolutely wash our hair in a magnesium bath, but there’s a bit of a technique to it if we want to avoid the dreaded "salt-hair" crunch. In this guide, we’re gonna break down the science of what happens to our follicles in the tub, how to tailor the experience to our specific hair type, and why the form of magnesium we use matters more than we think.
Can't decide? You don't have to! Give all four soaks a try with the soak stan favorite, the Stresscare Sampler 12-pack.

Before we dunk, it helps to understand what’s actually in the water. Most people use the terms "magnesium bath" and "Epsom salt bath" interchangeably, but they aren't the same thing. Epsom salt is magnesium sulfate. At Flewd, we focus on magnesium chloride hexahydrate because it's the most bioavailable form for transdermal absorption—meaning it’s easier for our skin to actually use.
When our hair enters this mineral-rich environment, several things happen simultaneously. First, the salt molecules interact with the hair cuticle. Our hair is made of overlapping scales called cuticles. In a warm bath, these cuticles lift slightly, allowing moisture and minerals to move in and out. This is why some of us find that a magnesium soak makes our hair feel thicker; the minerals provide a bit of "grip" and texture by subtly propping those cuticles up.
Second, there’s the scalp factor. Our scalps are essentially just an extension of our skin, but they’re packed with a higher density of hair follicles. Research suggests that these follicles might actually be the primary entry points for magnesium absorption. By soaking our heads, we aren't just treating our hair; we’re potentially giving our nervous systems a direct line to those anti-stress minerals.
Key Takeaway: Magnesium chloride is highly bioavailable, and our hair follicles may actually help our bodies absorb those minerals more effectively during a soak.
If we’re intentional about it, washing or soaking our hair in magnesium water can offer some pretty suuuuuper benefits for our scalp and overall hair health.
If we struggle with hair that feels limp, flat, or just generally uninspired, magnesium can act as a natural volumizer. By removing excess oils and providing that mineral "grip," it can give us that "beach hair" look without the actual sand and seagull drama. It’s particularly effective for those of us with fine hair who feel like every product just weighs us down.
Our scalps deal with a lot—dry shampoo buildup, pollution, and the general sweat of existing. Magnesium chloride is excellent at breaking down this gunk. It acts as a gentle clarifier, helping to lift away dead skin cells and product residue. Many of us find that a regular mineral soak can help manage an itchy or flaky scalp by keeping the environment clean and balanced.
For those of us dealing with "grease-trap" roots, magnesium can be a lifesaver. It helps regulate sebum (our natural skin oil) production. Instead of stripping the scalp completely—which just makes our skin panic and produce more oil—magnesium helps create a balanced environment. This may allow us to go a day or two longer between traditional washes.
We can't ignore the psychological benefit. Stress is a notorious thief of hair health, often contributing to thinning or dullness over time. By fully submerging ourselves—scalp and all—we’re signaling to our nervous systems that it’s time to downshift. When we use something like the Ache Erasing Soak, we’re attacking stress from the physical side (muscle relief) and the sensory side (citrus aromatherapy), which indirectly supports the healthy environment our hair needs to grow.
We have to be real: salt is drying. If we aren't careful, the same minerals that give us volume can also leave us with brittle strands.
Our experience with a magnesium bath is gonna depend entirely on what’s growing out of our heads. Here’s how we should approach it based on our specific hair needs.
We are the big winners here. A magnesium soak is like a reset button for oily roots. We can comfortably dunk our hair, massage the mineral water into our scalps, and let it sit for the duration of the bath. It’ll help lift that excess sebum and leave our hair feeling light and airy.
We need to be a bit more cautious. If our hair already feels like it’s struggling for moisture, we should avoid a full soak. Instead, we can use the "spray" method: mix a little bath water in a bottle and just target the scalp, or keep our hair in a bun and only dunk the very ends for a minute at the end of the soak. Always, always follow up with a heavy-duty conditioner.
Curly hair is naturally more prone to dryness because the oils from our scalp have a harder time traveling down the twists of the hair shaft. However, some of us find that magnesium gives our curls incredible definition and "bounce." The key is to treat it like a treatment, not a wash. Soak for a few minutes, then rinse and use a deep-conditioning mask immediately after.
Proceed with caution. If we’re in the first week of a new color, we should probably keep our hair dry. After that, we can indulge, but we should minimize the time our hair is submerged. A quick dunk and a fast rinse with fresh water is the safest bet to keep our color vibrant.
If we want the benefits without the drawbacks, we need a plan. Here is the best way to incorporate our hair into our 15-minute Flewd ritual.
What to do next:
- Grab a hair tie (just in case we decide against the dunk halfway through).
- Keep a bottle of fresh water or a detachable showerhead nearby for the final rinse.
- Choose a soak that matches our current stress level, like the Sads Smashing Soak for a mood lift.
Most of the horror stories about "salt hair" come from people using low-grade Epsom salts or swimming in the ocean. Ocean water contains a mix of sodium chloride and other minerals that can be incredibly harsh. Flewd soaks are built around magnesium chloride hexahydrate, which is much kinder to the skin and hair.
Because our formulas are 99% natural and free from parabens and phthalates, we aren't coating our hair in synthetic chemicals while we soak. We're also getting the benefit of targeted nutrients. For example, our Insomnia Ending Soak includes vitamins A and E, which are known to support skin and hair health. When we dunk our heads in that formula, we’re essentially giving ourselves a nutrient-dense mineral treatment.
We also have to talk about bioavailability. Transdermal absorption (absorbing through the skin) is a clever way to get nutrients into our systems without having to deal with the digestive upset that sometimes comes with oral magnesium supplements. By including our scalp—one of the most absorbent parts of our body—in the soak, we’re maximizing the efficiency of our 15-minute session.
There’s a lot of "wellness" noise out there, so let’s clear up a few things.
Myth: Magnesium will make our hair grow overnight. Magnesium is essential for protein synthesis and cellular health, which are necessary for hair growth. However, it isn't a magic potion. It helps create a healthy environment for growth by clarifying the scalp and reducing stress, but it won’t give us six inches of length by morning.
Myth: It’ll ruin a perm or chemical treatment. While it's not "ruinous," any salt-based soak can affect the longevity of chemical treatments. If we’ve just had a keratin treatment or a perm, we should wait at least two weeks before letting our hair soak in a magnesium bath.
Myth: We don't need to wash our hair afterward. While the magnesium cleanses the scalp, it doesn't replace the need for a proper rinse. If we leave the minerals in our hair to dry, they will crystallize, leaving our hair feeling stiff and looking dull. Always rinse.
The beauty of a Flewd soak is that it’s designed to be effective in a short window of time. We lead busy lives; we don't always have an hour to dedicate to a spa ritual. The nutrients in our soaks are designed to be absorbed quickly, with effects that many of our 100,000+ customers report lasting up to five days.
When we choose to wash our hair in the bath, we’re combining two self-care steps into one. We’re clarifying our scalps while we decompress our minds. It’s an efficient way to manage the physical symptoms of stress—like those tension headaches that often start at the base of the scalp—while also giving our hair a little boost.
"Our bodies treat a difficult email the same way they'd treat a lion. A magnesium soak is how we tell our nervous system the lion isn't real."
If we're gonna do this, let's do it right. Here’s the "too long; didn't read" version of how we handle our hair in a magnesium bath:
Washing our hair in a magnesium bath isn't just "okay"—it can be a legitimate part of our stress-care routine. By using a high-quality soak like those we make at Flewd Stresscare, we’re giving our scalps a hit of bioavailable magnesium chloride and targeted vitamins that can help with everything from oil control to volume. As long as we remember to rinse thoroughly and follow up with some hydration, our hair will come out feeling as refreshed as our minds do.
If we're ready to try it, we suggest starting with the Whole Mood Bundle so we can see how our hair and body react to different formulas. Whether we're trying to "smash the sads" or "erase the aches," there's a way to make our hair part of the healing process.
It isn't inherently damaging, but the salt content can be drying if we don't rinse it out properly. For most of us, a quick soak followed by a fresh-water rinse and conditioner will leave hair feeling voluminous rather than damaged.
We wouldn't recommend it. Leaving mineral salts in our hair can cause the cuticle to stay lifted, leading to significant dryness and potential breakage. Always rinse with fresh water before we go to bed.
Many find Epsom Salt Substitute for Bath to be superior because it’s more bioavailable and generally less "harsh" than the magnesium sulfate found in standard Epsom salts. It tends to be gentler on the skin and scalp while providing better mineral absorption.
Yes, many users report relief from scalp itchiness after a magnesium soak. The minerals help clarify product buildup and can support a healthier, more balanced scalp environment, which often reduces the urge to itch.
