Argan Oil for Hair.

What argan oil is, and who it suits

Argan oil is pressed from the kernels of the argan tree, which grows in southwest Morocco. It is light, absorbs reasonably quickly and carries a good amount of vitamin E and fatty acids, which is why it turns up in so many smoothing and shine products. On textured hair it earns its place as a finishing and sealing oil rather than a treatment oil, because it coats the strand and lays the cuticle flat instead of soaking deep into the cortex.

That makes it a good fit for fine to medium curls, wavy hair that hates heavy butters, and anyone whose ends look dull and feathery. Very coarse 4C hair often prefers something thicker underneath and argan on top as the final layer.

Pure oil or argan infused? They are not the same purchase

Pure oil is one ingredient doing one job. Shea Moisture 100% Pure Argan Oil and The One & Oily 100% Pure Argan Oil are the straightforward versions, useful on hair, skin and cuticles. A few drops go a long way, and you control exactly where it goes.

Argan infused products are formulated around the oil and do a specific job. Shea Moisture Argan Oil & Almond Milk Smooth & Tame runs across shampoo, conditioner and masque for frizz-prone hair. Cantu Argan Oil Leave-In Conditioning Repair Cream is a daily styler. Blue Magic makes three argan leave-in conditioners in tubs, and Eco Styler Argan Oil Styling Gel is the hold product. Buying the pure oil will not replace any of those.

Where argan fits in a wash day

The most reliable use is last. Damp hair, leave-in, cream or gel, then two or three drops of argan smoothed over the mid-lengths and ends to seal everything in and take the dullness off. It also works as a pre-wash treatment on dry hair an hour before shampooing, which softens the detangling process, and as a light refresher on day three when the ends look tired.

It is a sensible partner for heat too. XHC Argan Oil Heat Defense Leave in Spray is built for that, and pure argan on its own is not a heat protectant, so do not swap one for the other before a flat iron.

Argan in a British climate

Frizz here is mostly a humidity story. Summer air at 75 to 90 percent humidity swells the cuticle and lifts it, and a thin oil layer on the outside slows that down noticeably. Winter is the opposite: central heating pulls indoor humidity to around 30 percent, hair loses water to the room, and argan applied over a damp leave-in gives you something to hold onto.

Hard water in London and the south-east complicates it. Minerals on the strand already make hair feel coated, so pile oil on top of that and everything turns greasy without ever feeling soft. Clarify every few weeks, then go back to your usual amount.
