Argan oil is one of the most cited ingredients in the professional hair care market — and also one of the least rigorously analyzed. Its role goes far beyond a simple shine agent: its unique lipid composition and richness in antioxidant molecules make it an active whose action on the hair fiber follows precise biochemical mechanisms. Hairswiss describes the chemistry of argan oil and explains what truly sets it apart from other plant oils used in hair care.
Lipid Composition: What Makes Argan Oil Unique
Argan oil is cold-pressed from the kernels of the fruit of Argania spinosa, a tree endemic to Morocco. Its cosmetic value lies primarily in its fatty acid profile:
- Oleic acid (C18:1 ω-9): ~43–49% — a monounsaturated fatty acid whose linear structure allows efficient penetration into the hair cortex. It reduces transfibrillary water loss and restores fiber suppleness.
- Linoleic acid (C18:2 ω-6): ~29–36% — an essential polyunsaturated fatty acid, precursor of hair ceramides. It contributes to reconstituting the intercellular cement of the cuticle, reducing porosity and humidity-induced frizz.
- Palmitic acid (C16:0): ~12–15% — a saturated fatty acid that gives the oil good oxidation stability and a non-sticky texture.
- Stearic acid (C18:0): ~5–6% — contributes to viscosity and the immediate smoothing effect on the cuticle.
What fundamentally distinguishes argan from coconut or olive oil is its high ratio of linoleic acid (ω-6). On colored or bleached hair whose cuticle ceramides have been degraded, this ω-6 contribution plays a role of biomimetic reconstruction of the intercellular junction.
Tocopherols: Argan as an Antioxidant Shield
Argan oil contains an exceptionally high concentration of tocopherols — mainly γ-tocopherol and δ-tocopherol — reaching 620–900 mg/kg, approximately 2 to 3 times more than olive oil. These fat-soluble antioxidants protect the hair fiber from free radicals generated by UV radiation and the heat of styling tools, limiting the oxidative degradation of keratin chains.
Phytosterols and Triterpenes: Argan’s Least Known Actives
Argan oil also contains specific phytosterols — notably schottenol and spinasterol, absent in most other plant oils — as well as aliphatic triterpenes (butyrospermol, lupeol). These molecules exhibit anti-inflammatory and film-forming properties that complement the action of fatty acids, particularly on sensitive and reactive scalps.
Professional Argan Oil Products Available on cliCHair
Among the formulations that integrate argan oil in a technically coherent way, several references stand out on cliCHair.ch:
Argan Native Fluid — Edelstein
The Argan Native Fluid is a formulation based on native Argania Spinosa oil, enriched with keratin amino acids. Used as the final step in intensive regeneration protocols, it seals the cuticle, fixes the actives deposited in depth, and guarantees lasting shine.

Regeneration Ritual — Edelstein
The Regeneration Ritual by Edelstein combines native argan oil with Regenine (Hydroxypropyltrimonium Hydrolyzed Corn Starch) and aloe vera in an intensive regeneration protocol. The argan reconstitutes the interlamellar lipid film of the cuticle, the cationic active binds electrostatically to damaged keratin, while aloe vera maintains cortical hydration: a lipid-protein-humectant triad designed for fibers stressed by chemical treatments.ex: a lipid-protein synergy that maintains the straightening result while nourishing the fiber in depth.

Shimmer Smoothing Serum & Extender Frizz Free — Nika
The Shimmer Smoothing Serum and Extender Frizz Free by Nika are two anti-frizz and thermal protection finishing formulations, both enriched with argan oil. Designed for daily use or before each heat styling session, they deposit a protective lipid film on the cuticle that neutralizes electrostatic charges and prevents excessive atmospheric moisture absorption.

Argan vs. Other Hair Oils: A Clear Positioning
Coconut oil (rich in lauric acid C12, penetrating but potentially pore-blocking on oily scalps), jojoba oil (technically a liquid wax, film-forming but not nourishing), and castor oil (viscous, ideal for density but heavy to apply) each have their optimal application domain. Argan oil occupies a balanced position: penetrating without blocking, nourishing without weighing down, antioxidant without visible residual film. This versatile profile makes it one of the most widely used oils in premium professional formulations.
