The fastest way to get argan oil out of your hair is to shampoo twice in a row, letting the first wash break through the oil before the second wash actually cleans your hair. If your hair still feels greasy after that, a clarifying shampoo or a simple pantry ingredient can handle the rest. The approach you need depends on how much oil is weighing your hair down and how quickly you need results.
Why Argan Oil Is Hard to Rinse Out
Argan oil is roughly 80% unsaturated fat, with oleic acid making up 43 to 49% and linoleic acid another 29 to 36%. These fatty acids are hydrophobic, meaning they repel water. Running your hair under the faucet, even with hot water, won’t dissolve them. The oil clings to each strand and resists rinsing the same way cooking oil resists washing off your hands with water alone. You need a surfactant (the cleansing agent in shampoo) to bind to the oil molecules and carry them away.
This is also why a single, quick shampoo often isn’t enough when you’ve applied too much. The surfactants in your shampoo spend most of their energy binding to the heaviest layer of oil during the first wash, leaving little cleaning power for the oil that’s closer to the hair shaft itself.
The Double Shampoo Method
Double shampooing is the simplest fix and works for most people. The idea is straightforward: the first lather targets the heavy oil sitting on the surface. Once that’s rinsed away, the second lather gets direct access to the scalp and hair fiber to finish the job. Hair colorist and cosmetic chemist insights confirm this principle: surfactants initially bind to the “heavy stuff,” and only after that layer is gone can they clean effectively.
Here’s how to do it:
- First wash: Use a moderate amount of your regular shampoo. Work it through your hair for about 60 seconds, focusing on the oiliest areas. Don’t worry if it barely lathers. That’s normal when there’s a lot of oil present. Rinse thoroughly with warm water.
- Second wash: Apply shampoo again. This time you should get a fuller lather. Massage your scalp and work the suds down to the ends. Rinse completely.
Warm water helps here because it softens the oil slightly, making it easier for the shampoo to do its job. Avoid very hot water, though, as it can strip your hair of moisture you actually want to keep.
When to Use a Clarifying Shampoo
If double shampooing with your regular product doesn’t cut it, a clarifying shampoo is your next step. These are formulated with stronger surfactants designed to strip away stubborn product buildup, heavy oils, and residue that regular shampoos leave behind. One wash with a clarifying shampoo is typically enough to remove even a generous application of argan oil.
A few things to keep in mind: clarifying shampoos are effective precisely because they’re aggressive. Using one too often (more than once a week or so) can leave your hair dry and stripped. Think of it as a reset button, not an everyday product. Follow up with a lightweight conditioner on your ends to restore some moisture after using one.
The Apple Cider Vinegar Rinse
If you’d rather skip a special shampoo, an apple cider vinegar rinse can help dissolve oil buildup using what you already have at home. The acetic acid in the vinegar works to break down product residue on the hair shaft.
Mix one part apple cider vinegar with two parts water. After shampooing, pour the mixture over your hair and let it sit for a couple of minutes before rinsing it out with cool water. The smell fades quickly once your hair dries. This method is gentler than a clarifying shampoo and works well for moderate oil buildup rather than a full-on grease situation.
Quick Fix: Absorbing Excess Oil
Sometimes you don’t have time to jump in the shower. Maybe you applied too much argan oil right before heading out the door. In that case, a dry absorbent can soak up surface oil fast.
Cornstarch and arrowroot powder both absorb oil effectively. Arrowroot has a finer texture, so it blends in more smoothly and leaves less of a powdery residue. Sprinkle a small amount onto your roots or the greasiest sections, let it sit for two to three minutes, then brush it out thoroughly. Dry shampoo works on the same principle if you have some on hand. This won’t remove the oil from your hair, but it will cut the visible greasiness until you can properly wash it out.
For darker hair, cocoa powder mixed with cornstarch helps avoid the white cast that pure starch can leave behind.
Why Low Porosity Hair Holds Onto Oil
If your hair always seems to get weighed down by argan oil no matter how little you use, you may have low porosity hair. This means your hair’s outer cuticle layer is tightly sealed, so oils and treatments sit on the surface rather than absorbing into the strand. The result is buildup that feels heavy and greasy, even from a small amount of product.
For low porosity hair, the solution is twofold. First, use the clarifying shampoo method described above to remove the current buildup. Second, prevent the problem going forward by switching to lighter oils. Argan oil is a medium-weight oil, and low porosity hair handles lighter options (like grapeseed or a very small amount of jojoba) much better. When you do use argan oil, apply it to damp hair rather than dry, and use only a few drops warmed between your palms. The warmth helps open the cuticle slightly so the oil absorbs instead of just sitting on top.
Skip the Baking Soda
You’ll see baking soda recommended online as a natural oil stripper, but it’s one of the worst things you can put on your hair for this purpose. Baking soda has a pH of 9, which is strongly alkaline compared to healthy hair (which sits around pH 4.5 to 5.5). At that pH, it forces the cuticle layer to open wide, allowing excessive water absorption that breaks down the hydrogen bonds in keratin, the protein your hair is made of.
The consequences are measurable: lower elasticity, increased friction between hair fibers, cuticle damage, and ultimately breakage and fragility. It will remove the argan oil, yes, but at a cost to your hair’s structural integrity that isn’t worth it when gentler methods work just as well. A clarifying shampoo or vinegar rinse accomplishes the same goal without the damage.
Preventing Overuse Next Time
Most argan oil mishaps come down to using too much. A little goes a long way. For fine or medium hair, one to two drops is plenty. For thick or coarse hair, three to four drops is usually the upper limit. Always warm the oil between your palms first, then apply it to mid-lengths and ends rather than your roots. Your scalp already produces its own oil, so adding more there just creates greasiness.
Applying argan oil to damp hair (not soaking wet, not bone dry) helps it distribute evenly and absorb better. If you’re using it as a pre-wash treatment, apply it 20 to 30 minutes before showering so it has time to penetrate the hair shaft. That way, when you shampoo, the excess rinses out easily and you’re left with the conditioning benefits rather than a greasy film.
