You've probably seen those tiny, amber glass bottles sitting on the shelves of every high-end salon from Los Angeles to Paris. They call it "liquid gold." It’s argan oil. People swear by it. They say it makes their hair grow like crazy, but if you look at a bottle and expect a miracle mane overnight, you’re gonna be disappointed.
Honestly, the marketing is a bit much.
Argan oil, extracted from the kernels of the Argania spinosa tree native to Morocco, is packed with fatty acids and antioxidants. That’s a fact. But does it actually trigger biological hair growth from the follicle? Or are we just looking at a really fancy lubricant that stops your ends from snapping off? The truth is somewhere in the middle, and it’s a lot more interesting than "put this on your head and grow six inches."
The Biology of Argan Oil and Hair Growth
Most of what we know about argan oil comes from its chemical profile. It’s heavy on oleic and linoleic acids. These are essential for maintaining the skin barrier. When your scalp is healthy, your hair has a better chance of thriving. Think of it like soil. You can’t grow a prize-winning rose in dry, cracked dirt.
A study published in the Journal of Pharmacy & Pharmacology actually looked at how argan oil protects the hair shaft. It’s not necessarily about the oil "feeding" the root to make it grow faster. Instead, it’s about the tocopherols (Vitamin E). Argan oil is loaded with them. These compounds fight oxidative stress. We know from research by experts like Dr. Antonella Tosti that oxidative stress is a major player in hair thinning and premature aging of the follicle. By neutralizing free radicals, argan oil basically acts as a bodyguard for your scalp.
It’s protective. It’s not a stimulant like Minoxidil. It’s more of a long-term maintenance strategy.

Why Your Hair Feels Longer (Even If It Isn't)
We need to talk about breakage. This is where the argan oil for hair growth myth usually starts. When your hair is dry, the cuticle—the outer layer of the hair—lifts up. This makes the strands snag on each other, leading to split ends and snapping. If your hair is breaking off at the bottom at the same rate it’s growing from the top, you’re at a stalemate.
You feel like your hair is stuck at shoulder length forever.
Argan oil fills in those gaps in the cuticle. It’s a hydrophobic barrier. That’s just a science-y way of saying it keeps water from bloating the hair shaft and keeps the internal moisture from escaping. Because the oil has a small enough molecular structure to penetrate the hair slightly—though not as deeply as coconut oil—it increases elasticity. When your hair can stretch without snapping, you actually get to keep the length you grow.
Basically, you aren't growing hair faster; you're just losing less of it to your hairbrush.
The Scalp Microbiome Factor
If you have a crusty scalp, you aren't growing healthy hair. It’s that simple.

Seborrheic dermatitis and dandruff cause inflammation. Inflammation tells the hair follicle to enter the telogen (resting) phase early. This is why people with chronic scalp issues often see thinning. Argan oil has demonstrated anti-inflammatory properties. In Moroccan traditional medicine, it’s been used for centuries to treat skin infections.
Modern science backs some of this up. The triterpenoids found in the oil help with tissue repair. If you massage a few drops into your scalp, you’re doing two things. First, the physical act of massaging increases blood flow to the area. Second, the oil helps dissolve excess sebum and soothe irritation. It’s a double-win for the follicle environment.
Don't Fall for the "Pure" Trap
Not all argan oil is equal. If you buy a "Moroccan Oil" blend that lists dimethicone or cyclomethicone as the first two ingredients, you aren't using argan oil. You’re using silicone with a hint of argan perfume.
Silicones aren't inherently evil. They make hair shiny. But they don't provide the biological benefits of the fatty acids we're talking about. Look for "100% Argania Spinosa Kernel Oil." It should smell slightly nutty—sort of like popcorn or toasted seeds. If it smells like nothing, it’s been over-processed and likely lost its antioxidant punch. If it smells like perfume, it’s a cosmetic blend.
How to Actually Use It for Results
Stop dumping it on your head. Seriously.

Argan oil is heavy. If you have fine hair, you’ll look like you haven't showered since 2022. The best way to use argan oil for hair growth is as a pre-wash treatment.
- Warm up about a tablespoon of oil in your hands.
- Massage it into the scalp for a full five minutes.
- Work the remainder through the ends.
- Leave it for thirty minutes.
- Wash it out with a sulfate-free shampoo.
Doing this twice a week is plenty. If you have thick, curly, or "coily" hair (Type 3 or 4), you can use it as a sealant on damp hair. This mimics the natural sebum that has a hard time traveling down the twists of a curly hair strand.
The Limits: When Argan Oil Isn't Enough
We have to be real here. If you are experiencing androgenetic alopecia (pattern baldness) or telogen effluvium from a thyroid issue, argan oil is a band-aid on a broken leg. It cannot block DHT (dihydrotestosterone), which is the hormone responsible for shrinking follicles in genetic hair loss.
If you see your part widening or you’re losing clumps of hair, go see a dermatologist. Don't waste six months hoping a nut oil will fix a hormonal imbalance. Use argan oil as a secondary support system, not your primary treatment.
Actionable Steps for Better Hair
If you want to integrate this into a routine that actually yields length, follow these steps:
- Check the label: Ensure "Argania Spinosa" is the only ingredient. Avoid blends with "Fragrance" or "Parfum" if you have a sensitive scalp.
- The Scalp Massage: Commit to a 5-minute scalp massage with the oil twice a week. This mechanical stimulation is just as important as the oil itself for encouraging blood flow.
- Protection over Growth: Use a tiny drop on your ends every single night before bed. This prevents "sleep friction" breakage against your pillowcase.
- Internal Support: Remember that hair is built from the inside. Pair your topical argan oil use with a diet rich in biotin, zinc, and iron.
- Temperature Control: Argan oil has a high smoke point, but it isn't a miracle heat protectant. Keep your curling irons under 350 degrees Fahrenheit to avoid "cooking" the oil into your hair fibers.
Argan oil is a tool, not a magic wand. It keeps the hair you have healthy, flexible, and attached to your head. That is the secret to "growth" that most brands won't tell you.
