Moroccanoil Treatment is worth it if your hair is dry, frizz-prone, color-treated, or medium to thick and you want a polished, glossy finish with very little effort. Compared with OGX Renewing + Argan Oil of Morocco, it feels smoother and more refined, but the gap is smaller than the premium positioning suggests, and Kérastase Elixir Ultime is a slightly lighter pick for finer lengths.
Overview
Moroccanoil Treatment is a leave-in styling oil-serum from Moroccanoil. Its main promise is simple: soften rough ends, tame frizz, boost shine, and help hair look smoother with a very small amount. This review focuses on the original formula, which is richer than Treatment Light.

Who It’s For
This is a strong fit for dry ends, coarse strands, blow-dried hair, and anyone who wants that glossy, smoothed finish after styling. If your hair is fine, very low-density, or gets oily quickly, you can still use it, but only in tiny amounts and usually just on the ends.
Performance & Feel
The first thing to know is that Moroccanoil Treatment does not behave like plain argan oil. It feels more like a silky serum, which is why it spreads so easily and makes hair look smoother almost right away. On damp hair, it works best as a prep step before blow-drying. A small amount on shoulder-length hair helped with slip, cut down on puffiness, and left the ends feeling softer instead of crispy.
On dry hair, it shines as a finishing product. Warming a half pump between the hands and skimming it over the last few inches gave the prettiest result: less halo frizz, more shine, and a smoother outline without stiffness. It also does a nice job disguising tired, rough ends, though it does not truly repair split ends. The improvement is cosmetic, but it is immediate and easy to see.
Where it gets trickier is application control. If you use too much, hair can cross from glossy to heavy pretty fast, especially if your texture is fine or naturally straight. The scent is another dividing line. It smells luxurious and lasts for hours, but it is not subtle. If you are sensitive to fragrance, that alone may be enough to skip it.
Compared with simpler drugstore oils, the finish is more polished and consistent. Hair looks less piecey and more intentionally smoothed. Still, the jump in results is biggest on dry or frizz-prone hair. If your hair is already healthy, straight, and easy to manage, the difference is nice but not dramatic enough to make this an automatic buy.
Where hair oil-serums Usually Goes Wrong
Most reviews stop at shine and frizz control, but hair oil-serums usually go wrong on dosage and placement. With Moroccanoil Treatment, that matters more than usual because the formula is rich. If you use the amount many people instinctively reach for, especially on fine hair or near the roots, it can cross from polished to coated fast. The real test is not whether it makes hair look smoother, it is how narrow the margin is between glossy and greasy.
This is also where expensive oils can disappoint people who technically bought the right product. On dry, medium-to-thick, color-treated hair, a half pump to one pump through damp mid-lengths and ends can look excellent. On fine, low-density, or oil-prone hair, even that may be too much, and the best result often comes from using a partial pump only on the last few inches after styling. A lot of reviews do not spell that out clearly enough, which leads people to think the formula is bad for their hair type when the bigger issue is that richer oil-serums demand more precision than lighter finishing products.
The other common miss is buildup over time. Because this kind of product makes hair feel instantly softer, it is easy to keep layering it between wash days, especially on heat-styled ends. That can dull movement and make lengths feel heavy by day two or three. If you want the salon-like finish this product does well, it works best as a controlled finishing step, not a repeatedly reapplied fix throughout the week.
Advantages & Disadvantages
Pros
- Smooths frizz quickly and leaves hair noticeably softer.
- A little goes a long way, so one bottle lasts longer than you might expect.
- Works well on both damp hair and dry ends.
- Gives a glossy, salon-finished look that many lighter oils do not match.
Cons
- Easy to overapply on fine or low-density hair.
- Strong fragrance will not suit everyone.
- It is silicone-based, so it will not appeal to shoppers looking for a pure oil or a curl-method formula.

💡 The Editor's Closing Thoughts
Moroccanoil Treatment earns its reputation. It is not magic, and it is not the best value for every hair type, but it is a dependable smoothing oil that makes dry, frizz-prone hair look better fast. If your hair is medium to thick and you love a polished finish, it is worth the premium. If your hair is fine or you want a more natural, fragrance-free formula, I would pass.

Frequently Asked Questions ▾
Is Moroccanoil Treatment pure argan oil?
No. It is better understood as a styling serum that uses smoothing silicones alongside argan oil. That is why it feels silky in the hands and gives instant slip and shine.
How much should you use?
Start smaller than you think. For fine hair, a half pump or even less is enough. For medium to thick hair, one pump is usually a better starting point, with more only if your hair is very long or very dense.
Can you use Moroccanoil Treatment on dry hair?
Yes. It works very well as a finishing oil on dry hair, especially on the ends and any frizzy outer layer. Keep it away from the roots unless your hair is extremely dry.
Is it good for curly hair?
It can be useful for sealing ends, scrunching out a cast, or taming surface frizz, but it is not silicone-free. If that matters to your routine, check the ingredient list before buying.
Is it worth choosing over cheaper argan oil products?
For dry, coarse, or frequently heat-styled hair, yes, because the finish is smoother and more consistent. For healthy fine hair that only needs a bit of shine, cheaper options can get close enough that the premium formula is harder to justify.
