Moroccanoil Treatment Hair Oil
The original argan oil treatment. Frizz control, shine, and heat protection in a single application.
What Is Moroccanoil Treatment Hair Oil?
Moroccanoil Treatment is a multi-use hair oil built around argan oil as its active ingredient. It was originally developed as a professional salon product and is widely credited with starting the argan oil haircare trend in North America. The formula is alcohol-free, and the bottle is made from 40% recycled glass. It's also PETA certified cruelty-free.
The product comes in three sizes and two formulas: the Original (reviewed here) and Treatment Light, which is designed specifically for fine or light-coloured hair. The Original is meant for medium to thick hair, or any hair type that needs more nourishment and control.
It's described as a styling oil, leave-in conditioner, and finishing product in one — you can apply it to damp hair before blow-drying, or to dry hair to smooth frizz and add shine. One independent study cited by the brand found a single application increased shine by up to 118%.
Moroccanoil has been ranked the #1 hair oil brand in the US by The NPD Group for multiple consecutive years, which is one of the rare instances where a brand claim is actually backed by third-party data.

In-Depth Review
TL;DR - Too Long, Didn't Read
If you have medium to thick hair that tends toward frizz, dryness, or damage — this oil delivers. Frizz control is the strongest benefit and it's visible from the first use. Fine-haired users can make it work too, but only with very small amounts; anything more and your hair will feel heavy. The scent is a defining feature people either love immediately or find overpowering at first. The price is high, but the bottle lasts a long time when used correctly.
What makes it different from other argan oils
There are hundreds of argan oil products on the market, most of them much cheaper. The difference with Moroccanoil Treatment comes down to formulation and stability. Pure argan oil on its own doesn't absorb well without a carrier or emulsification. Moroccanoil's formula combines argan oil with linseed extract and vitamins in a way that allows faster absorption and a weightless finish — something most drugstore argan oils don't manage.
The other meaningful difference is consistency. Amazon reviewers who have used the product for years consistently report the same result, bottle after bottle. That kind of reliability at scale is harder to fake than a good set of marketing claims.
It's also worth noting the formula hasn't changed drastically since launch. Brands often quietly reformulate their bestsellers to cut costs. Moroccanoil has kept this one close to its original version, which is partly why the long-term loyalists keep coming back.
How it performs: frizz, shine, and heat protection in real use
Frizz control is where this product earns its reputation. Applied to damp hair before blow-drying, it smooths the cuticle and makes hair noticeably easier to style. Hair stays calmer through humidity for several hours after use — not all-day perfection, but a marked improvement compared to styling without it.
The shine boost is real but front-loaded. Hair looks noticeably more polished immediately after application, but the visual shine effect fades faster than the smoothing benefits. The frizz control tends to last through to the next wash; the glossy finish does not.
Heat protection is a benefit that gets undermentioned on most review sites. The oil creates a light barrier between your hair and heat tools, which matters for anyone who blow-dries or flat-irons regularly. It won't replace a dedicated heat protectant for extremely high heat, but for everyday blow-drying it does the job.
One thing that surprises first-time users: how little you actually need. One to two pumps for thick, long hair. Half a pump for short or fine hair. Getting the dosage right makes a significant difference in results.
Fine hair vs. thick hair: what to expect
This is the section most review sites skip, so it's worth being direct.
For medium to thick hair, the Original formula works well without much adjustment. Frizz reduction, detangling, and shine all come through clearly. You'll feel the difference in the first use.
For fine hair, the situation is more nuanced. A few Amazon Canada reviewers with fine hair report good results when they use very small amounts — half a pump maximum, focused on mid-lengths and ends only. One reviewer noted she uses it specifically for sleek buns and flyaway control rather than all-over treatment, which works well. However, anything approaching a full pump on fine hair will weigh it down and flatten volume.
Moroccanoil actually makes Treatment Light for exactly this reason. If your hair is fine or colour-treated and lacking density, the Light version is the more appropriate product. The Original is designed for hair that can handle heavier conditioning.
Reddit's r/finehair community has had positive threads about the brand, with the caveat that most fine-haired users see better results with the lightweight products in the line rather than the Original.
Is the premium price justified?
Straightforwardly: yes, but only if you use it correctly.
The most common complaint from disappointed buyers is that the bottle "ran out too fast." Almost without exception, those buyers were using too much per application. One to two pumps is genuinely enough for most hair lengths. Used correctly, the 3.4 fl oz bottle lasts most people three to four months of daily use — which brings the cost per use down considerably compared to the sticker price.
Compared to alternatives like Olaplex No.7 or Oribe Gold Lust, Moroccanoil Treatment is competitively priced for what it delivers. Cheaper argan oils exist, but the absorption quality and finish are noticeably different. This is one of the few categories where the price premium reflects a real formulation difference rather than just brand positioning.
The Amazon.ca listing has Amazon's Choice status and ranks #2 in Hair Treatment Oils — not from advertising, but from sustained sales volume and review quality. That's a reliable signal at this scale.
What Real Users Say
The pattern across Amazon Canada reviews is consistent: buyers across different hair types mention frizz reduction and softness as the first things they notice.
A March 2026 verified purchase review reads: "I've used Moroccanoil Treatment for a long time and it has never failed me. It makes my hair softer, smoother, and much easier to manage while controlling frizz and adding a healthy shine. A small amount goes a long way, and it doesn't leave my hair feeling greasy or heavy."
Another Canadian buyer who switched from Olaplex wrote: "It soaks in quickly leaving my and my daughter's hair shiny, hydrated and smelling great." A UK buyer who had it recommended by their hairstylist noted both the softness and the ease of detangling as immediate improvements, adding: "My hairdresser told me with oils like this, if you pay a premium you get a premium result — and for how long it lasts, it's worth the price."
The most instructive critical feedback comes from fine-haired users. A March 2024 Canadian review from someone with very fine hair gave it four stars, noting: "I wouldn't recommend being generous with the amount of oil you use as it definitely weighs your hair down. For fine-haired people, instead of using hair wax or gel for a slick look, use Moroccanoil Treatment in small amounts — it will leave your hair looking shinier and healthier." That framing is actually a good way to think about dosing for finer hair types.
The scent generates strong opinions in both directions. Most buyers describe it as a standout feature — a spicy amber and floral combination that reads as luxurious without being heavy. A smaller number find it too strong for scent-sensitive environments, which is worth knowing before buying.
If frizz, dryness, or flat styling results are problems you deal with regularly, this is one of the most consistently rated solutions available on Amazon right now. It ranked #2 in Hair Treatment Oils on Amazon.ca with over 87,000 reviews for a reason.
Is it worth it?
For medium to thick hair that deals with frizz, dryness, or heat damage: yes, this is a legitimate product that delivers consistent results. The frizz control is the strongest argument for buying it, and it holds up across thousands of verified reviews and years of use.
For fine hair: it can work, but only with careful dosing. If you're not disciplined about using minimal amounts, the Treatment Light version is a better fit.
The one honest caveat is the price. This is a premium product, and if you're not dealing with frizz, damage, or styling difficulty, a cheaper option might serve you just as well. But if those are problems you already have, this oil tends to actually solve them rather than just temporarily mask them.
Who It's Best For
People with dry, frizzy, or coarse hair looking for daily frizz control
Anyone who uses heat tools regularly and wants a light layer of protection
Colour-treated or chemically processed hair that needs ongoing conditioning

Fine-haired users willing to use very small amounts and stay disciplined with dosing
Anyone who's used salon products and wants the same results at home
Not recommended for:
Fine-haired users who tend to over-apply products
People who are sensitive to fragrance (the scent is distinctive and persistent)
