Argan oil is everywhere. Every shampoo aisle, every blowout bar, every “anti-frizz serum” in the chemist. Most of it is 90% silicones and 1% argan, and most people use even the real version wrong.
Used properly, cold-pressed argan oil is genuinely one of the most useful single ingredients in hair care — high in tocopherols (vitamin E), oleic and linoleic fatty acids, and squalene, all of which the hair shaft will actually absorb. Used incorrectly, it sits on top of your hair like a wet blanket and makes you look like you forgot to shower.
Here is the proper way, and the four mistakes to stop making today.
What argan oil actually does for hair
- Smooths the cuticle. The fatty-acid profile fills the rough scales of damaged hair, so light reflects evenly. This is what people call “shine”.
- Reduces moisture loss. A thin lipid film slows trans-epidermal water loss from the hair shaft, which keeps lengths supple.
- Protects against heat. Argan starts to break down at roughly 200°C — high enough to act as a partial heat protectant for blow-dryers (most run around 60-110°C) but not full-blast irons (180-230°C).
- Calms the scalp. Squalene and vitamin E support the sebaceous balance — useful for dry, itchy, or flaky scalps.
- Reduces breakage over time. Weekly pre-wash treatments reduce protein loss during washing by up to 30%, according to multiple cosmetic-chemistry studies.
The 4 mistakes almost everyone makes
Mistake 1 — Applying it to dry hair as a leave-in
This is the single most common error. Dry hair has a closed cuticle. Oil applied to a closed cuticle cannot penetrate — it sits on top, weighs everything down, and turns dirty within hours. Argan absorbs only when the cuticle is open, which happens when hair is warm and damp.
The fix: apply 2-4 drops to towel-dried hair (damp, not wet), focusing on the lengths and ends. Never the scalp.
Mistake 2 — Using too much
The standard rule from professional stylists: two drops for shoulder-length hair, four for mid-back, six for waist-length. More than that and you have a greasy mess that no amount of shampoo will fix until the next day.
The fix: dispense into your palm first, rub palms together to warm and disperse, then run from mid-shaft to tips. Whatever is left, smooth lightly over the top layer.
Mistake 3 — Applying to the scalp
Argan on a healthy scalp clogs the follicles, traps sebum, and triggers the rebound oiliness it was supposed to prevent. The only exception: as a pre-wash overnight mask for chronically dry, flaky scalps (and even then, weekly maximum).
The fix: mid-shaft to ends only, always. Treat the scalp separately with a weekly rhassoul clay mask.
Mistake 4 — Buying the wrong “argan oil”
Roughly 70% of products labelled “argan oil” in Western drugstores are silicone-heavy serums with a tiny percentage of actual argan. They smell strongly perfumed, they come in plastic bottles, and they cost suspiciously little. None of those things are true of real argan oil.
The fix: see the buying guide below.
How to use argan oil properly (three routines)
Daily routine — anti-frizz, shine
- Wash and condition as normal. Towel-dry until hair is just damp (no dripping).
- Dispense 2-4 drops into your palm.
- Rub palms together to warm.
- Apply from mid-shaft to ends. Comb through with a wide-tooth comb.
- Air-dry or blow-dry as usual. Skip product on the scalp.
Weekly pre-wash treatment — repair and strength
- 30-60 minutes before washing, warm 1 tablespoon of argan oil between your palms.
- Section the hair and work the oil from roots to tips — yes, including scalp this one time.
- Cover with a shower cap, wrap in a warm towel. Leave 30-60 minutes.
- Wash with a gentle shampoo (double-cleanse the first wash to remove the oil).
- Condition the ends only.
Monthly deep treatment — for damaged or chemically-treated hair
Combine 2 tablespoons argan oil with 1 tablespoon honey and 1 egg yolk. Apply to dry hair, cover, leave 45 minutes, then shampoo out. Sounds odd; works exceptionally well for bleach-damaged or relaxed hair.
How to spot real argan oil
- Cold-pressed and unrefined. Should say “100% pure argan oil” with no other ingredients on the label.
- Sourced in Morocco. Specifically the Souss-Massa region — the only place argan trees grow. “Made with Moroccan argan oil” in 100ml of mineral oil does not count.
- Sold in dark glass. Argan oxidises fast in light and plastic. Clear or plastic bottles mean it has already started degrading.
- Smells faintly nutty. Not perfumed, not floral. A subtle roasted-nut smell is real. No smell at all means it has been deodorised (still works, less authentic).
- Costs €25-50 per 100ml. Anything under €15 is almost certainly cut. Real argan takes 8-12 hours of manual labour per litre to produce.
- Cooperative-sourced. Look for “fair-trade” or “women’s cooperative” on the label. The major Souss cooperatives — Tighanimine, Ajddigue, Marjana — supply most of the world’s authentic argan oil.
The EARTD argan oil on Souk Atlas is cold-pressed by the Tighanimine cooperative, dark amber glass, 100% pure, traceable to harvest batch.
Cosmetic argan vs culinary argan
Real argan oil comes in two forms: cosmetic (raw, unroasted) and culinary (lightly toasted, used for dipping bread and finishing tagines). They look almost identical but smell completely different. Never put culinary argan on your hair — the roasted aroma will not wash out for days.
Argan oil FAQ
Will argan oil grow my hair faster?
It will not directly stimulate growth, but by reducing breakage at the lengths, it can give the appearance of faster growth (because less is lost). For actual growth stimulation, rosemary essential oil applied to the scalp has stronger trial data.
Can I use argan oil on bleached hair?
Yes — bleached hair is exactly the hair that benefits most. Use the weekly pre-wash treatment plus daily light application to ends.
Does argan oil cause acne?
Not on the scalp if used correctly (lengths only). On the face it is non-comedogenic for most skin types — comedogenicity rating of 0.
Can I cook with cosmetic argan oil?
You can, but it tastes flat — the toasting in culinary argan is what gives it its hazelnut character. Better to use cosmetic argan for skin and hair only.
How long does a bottle last?
A 100ml bottle gives roughly 50 daily applications (4 drops each). Used properly that is 6-8 weeks per bottle.
Does argan expire?
Yes — 12 months once opened. Store cool, dark, sealed. If it ever smells rancid, throw it out.
The bottom line
Argan oil is genuinely one of the best things you can put on your hair — and one of the most-faked products in the beauty industry. Buy the real version once (€25-50, dark glass, cooperative-sourced), use 2-4 drops on damp lengths, never touch the scalp daily, and stop expecting it to be a leave-in. Within a month, you will see what your hair was supposed to look like all along.
