Beautiful hair can change the entire impression of a look.
A simple outfit can feel more polished when the hair looks glossy and well cared for, while even the most elaborate beauty routine can lose some of its impact when the lengths appear dry, frizzy or dull.
That doesn’t mean perfectly styled hair has to look overly done. In fact, some of the most luxurious-looking hair is the opposite: soft, smooth, healthy-looking and naturally reflective.
This is where a good hair serum or oil can become one of the most useful finishing steps in a beauty routine.
Rather than trying to completely transform your hair, the right formula can help enhance what you already have — adding shine, smoothing the appearance of frizz, softening dry-looking ends and giving the lengths a more polished finish.
And because Dubai’s heat, humidity and frequent exposure to air conditioning can make hair particularly difficult to manage, a carefully chosen finishing product can be especially useful here.
A beautiful haircare routine doesn’t stop in the shower; the right finishing products can add softness, shine and polish, which is why choosing the right shampoo and conditioner is equally important.
Why Hair Serums and Oils Deserve a Place in Your Beauty Routine
Hair oils and serums have become much more sophisticated than the heavy, greasy products many people remember.
Modern formulas can be lightweight enough for fine hair while still providing noticeable shine and softness. Others are designed for dry, coarse or damaged hair that needs a richer treatment.
The important thing is understanding what you’re actually looking for.
A product designed primarily for shine won’t necessarily provide the same benefits as a treatment designed for damaged hair. Likewise, a rich oil that works beautifully on thick, dry lengths may be too heavy for very fine hair.
The best luxury haircare routine isn’t about owning the most products.
It’s about choosing the right ones for your hair.
If you approach skincare in the same way, you’ll recognise the philosophy. Our guide to The Ultimate Luxury Skincare Routine: Morning & Night Steps for Glowing Skin takes a similar approach to building a considered beauty routine rather than simply accumulating products.
DID YOU KNOW?
Hair looks glossy when its surface reflects light smoothly. When the outer surface is rougher or uneven, light scatters in different directions and the hair can appear duller. This is one reason smoothing and conditioning products can make such a visible difference to the appearance of the lengths.
Hair Oil vs. Hair Serum: What’s the Difference?
The terms hair oil and hair serum are sometimes used interchangeably, but they can serve slightly different purposes.
Hair Oils
Hair oils are generally associated with nourishment, softness and shine.
Depending on the formula, they can be used as a finishing product, a pre-shampoo treatment or as part of a broader haircare ritual.
They can be particularly useful for dry-looking lengths and ends, although the right texture depends on your hair type.
Hair Serums
Hair serums tend to be more focused on smoothing, finishing and managing the appearance of frizz.
Many modern formulas are lightweight and designed to leave the hair looking polished without making it feel coated.
Some products combine the characteristics of both categories, which is why it’s more useful to look at the actual formulation and intended use rather than relying solely on whether the bottle says “oil” or “serum.”
How to Choose the Right Formula for Your Hair
Before choosing a luxury hair oil or serum, ask yourself three questions.
1. What is your hair texture?
Fine hair usually needs a lighter touch.
Thick, coarse or highly textured hair can often accommodate richer formulas.
If your hair becomes flat easily, a heavy oil may not be the best choice. If your lengths are extremely dry, however, an ultra-light serum may not provide the finish you’re looking for.
2. What is your main concern?
Are you looking for:
- More shine?
- Less visible frizz?
- Softer ends?
- A smoother blow-dry?
- Help managing humidity?
- A finishing product for special occasions?
- A treatment for damaged lengths?
Your answer should determine the type of product you choose.
3. When do you want to use it?
Some formulas work particularly well on damp hair before styling.
Others are designed to be applied after styling.
Some can do both.
And richer oils may be better suited to occasional treatments rather than everyday finishing.
Understanding this before you buy will help prevent the common mistake of choosing a beautiful product that simply isn’t right for your routine.
Choosing Hair Oils for Fine Hair
Fine hair can benefit enormously from the right serum or oil, but it requires restraint.
The objective isn’t to coat the hair.
It’s to give the lengths enough product to create softness and shine while maintaining movement.
Lightweight formulas are generally easier to work with.
Start with a very small amount and concentrate it on the mid-lengths and ends.
If the hair still feels dry, you can add a little more.
It’s much easier to build up a lightweight product than to recover from using too much.
Choosing Hair Oils for Thick or Coarse Hair
Thicker or coarser hair can often handle richer textures.
If your lengths tend to feel rough or dry, a nourishing oil can provide a more substantial finishing effect than an ultra-light serum.
But even here, more isn’t necessarily better.
Warm the product between your palms and distribute it gradually through the lengths rather than concentrating it in one area.
The ideal result is hair that feels soft and touchable, not saturated.
Choosing a Product for Dry or Damaged Hair
If your hair has been coloured, bleached or regularly exposed to heat styling, the ends may be where you notice the most dryness.
A nourishing oil or treatment-focused serum can help improve the appearance and feel of those lengths.
However, it’s important not to treat a finishing oil as a miracle repair treatment.
Haircare still begins with appropriate cleansing, conditioning and treatments. A serum or oil is best viewed as one part of that routine.
For another example of adapting your beauty routine to Dubai’s environment, see our guide to Best SPF to Survive Dubai’s Summer Heat. The principle is similar: the best beauty routine is one that takes your environment into account.
Choosing a Product for Frizz and Humidity
Humidity can make already-styled hair look completely different within minutes.
If your main concern is frizz, look for a formula specifically designed to smooth the appearance of the hair and control flyaways.
This is particularly relevant in Dubai, where outdoor humidity and indoor air conditioning can create very different conditions for your hair.
The trick is not to eliminate your natural texture.
Instead, the goal is to make the hair look controlled, polished and intentional.
STYLE TIP
For the most natural-looking shine, warm a tiny amount of oil between your palms before applying it to your hair. Start at the mid-lengths and ends, then use whatever remains on your hands to lightly smooth the surface. This creates a softer finish than applying a large amount directly to one section.
How Much Hair Oil Should You Use?
This is one of those beauty situations where less is usually more.
Start with a very small amount.
Fine or short hair may need only a drop or two, while longer or thicker hair may require more.
The exact amount will depend on the product, so always follow the individual manufacturer’s instructions.
A useful rule is to build gradually rather than apply generously from the beginning.
If your hair looks greasy, flat or visibly coated, you’ve probably used too much.
If it looks soft, smooth and reflective while retaining movement, you’ve found the right balance.
When Should You Apply Hair Serum or Oil?
There are three common moments when these products can be useful.
Before Styling
Some formulas can be applied to damp or towel-dried hair before blow-drying.
This can help smooth the hair and, depending on the product, provide heat protection.
Always check the manufacturer’s instructions rather than assuming every oil offers heat protection.
After Styling
A small amount can be used as a finishing step.
This is particularly useful for smoothing the ends, adding shine and taming visible flyaways.
As a Treatment
Some oils are designed for use before shampooing or as a more intensive treatment.
These are generally richer and shouldn’t automatically be treated like everyday finishing oils.
Don’t Confuse Shine With Healthy Hair
A beautiful glossy finish can make hair look instantly healthier, but appearance and hair condition aren’t exactly the same thing.
A serum can smooth the surface.
An oil can add shine.
A styling product can temporarily improve the appearance of dry ends.
But maintaining healthy-looking hair also requires appropriate washing, conditioning, treatment and protection from excessive heat.
Think of your serum or oil as the finishing touch, rather than the entire routine.
For another beauty finishing step, our guide to The Top Luxury Foundations That Look Like Real Skin explores the same concept from a makeup perspective: the best luxury products often enhance rather than overwhelm.
What Makes a Hair Oil Feel Truly Luxurious?
Luxury isn’t simply about the price tag.
A beautiful hair product should ideally combine an effective formula with an enjoyable experience.
That might mean a sophisticated fragrance, elegant packaging, a lightweight texture, a beautifully designed bottle or simply the feeling that the product fits seamlessly into your beauty ritual.
The best products also make sense for the person using them.
If you have fine hair, a beautifully packaged rich oil isn’t necessarily luxurious for you if it leaves your hair flat.
If you have dry, thick hair, a tiny lightweight serum that doesn’t provide enough nourishment isn’t necessarily the right investment either.
Luxury is ultimately about fit.
And that brings us to the products themselves.
There is no single luxury hair oil that will be perfect for everyone. The best choice depends on your hair texture, concerns and the finish you want.
The following selection focuses on products that bring something distinctive to the category — from iconic all-rounders to treatment-focused formulas and ultra-luxurious oils.
1. Kérastase Elixir Ultime L’Huile Originale — Best All-Rounder
If you want one versatile luxury hair oil that can fit easily into several stages of your routine, Kérastase Elixir Ultime L’Huile Originale is one of the strongest choices.
The current Kérastase UAE formula is a leave-in oil designed for all hair types, with shine, softness and anti-frizz benefits. The brand states that it provides heat protection up to 230°C and can be used on damp or dry hair, including before blow-drying and as a finishing touch.
That versatility is what makes it stand out.
You can use it when your hair is damp, after styling or for a small touch-up on the ends later in the day.
Best for: All hair types, shine, smoothing and everyday use.
Why it stands out: It’s one of the most adaptable options in the edit.
2. Kérastase Gloss Absolu Glaze Drops — Best for a Glossy Finish
If your priority is shine, Kérastase’s Gloss Absolu range is worth looking at.
The Glaze Drops are particularly appealing for anyone who wants that sleek, reflective finish associated with beautifully polished hair.
This is the kind of product to reach for when your hair already looks reasonably healthy but needs that final touch of gloss and smoothness before you head out.
Best for: Gloss, smoothness and a polished finish.
Why it stands out: It is particularly suited to the “glass hair” aesthetic without requiring an elaborate styling routine.
3. K18 Molecular Repair Hair Oil — Best for Damaged Hair
For coloured, bleached or heat-styled hair, K18 Molecular Repair Hair Oil takes a more treatment-focused approach.
The current UAE listing describes it as a lightweight oil designed to strengthen and repair damage while also reducing frizz and enhancing shine. It uses K18PEPTIDE technology alongside ingredients including avocado oil, sunflower oil, hemisqualane and squalane. Sephora UAE also lists heat protection up to 232°C.
This makes it particularly interesting if you want your finishing product to do more than simply create temporary shine.
Best for: Damaged, chemically treated or heat-styled hair.
Why it stands out: It combines a lightweight finishing texture with a repair-focused formula.
4. Oribe Gold Lust Nourishing Hair Oil — Best Luxury Finishing Oil
Oribe Gold Lust Nourishing Hair Oil has exactly the kind of glamorous positioning you’d expect from a luxury haircare brand.
It’s designed for those moments when you want the final step of your routine to feel indulgent as well as effective.
The product is currently listed among UAE luxury hair oils by Ounass, alongside brands such as Sisley, Augustinus Bader and Kérastase.
For Fancylicious, I particularly like this as the beauty-editor’s finishing oil: the kind of product that belongs on the vanity and gets pulled out before an evening occasion or polished blowout.
Best for: Luxury finishing and polished-looking hair.
Why it stands out: It brings together the sensory appeal of luxury haircare and a sophisticated finishing step.
5. Sisley Hair Rituel Precious Hair Care Oil — Best Ultra-Luxury Choice
If we’re talking about truly high-end beauty, Sisley Hair Rituel Precious Hair Care Oil deserves a place here.
And unlike some luxury hair products, this one has a particularly clear connection to the article’s central theme.
Sisley describes the oil as providing nutrition, radiance and softness, with a lightweight texture designed not to weigh hair down. Its formula includes passion fruit, shea, cottonseed and moringa oils.
It’s designed for all hair types and can be used on damp or dry hair, making it suitable for both treatment and daytime touch-ups.
Best for: A truly indulgent haircare ritual and glossy, soft-looking hair.
Why it stands out: It feels like the haircare equivalent of investing in a beautiful luxury skincare treatment.
6. Augustinus Bader The Hair Oil — Best Treatment-Focused Luxury Option
Augustinus Bader is better known for its skincare, but The Hair Oil makes an interesting addition to a luxury haircare routine.
The current UAE Sephora listing describes it as a lightweight, fast-absorbing oil designed to improve the look and feel of hair, with a focus on nourishment, shine, conditioning and protection. The formula includes argan, pomegranate and baobab oils alongside vitamin E.
It’s particularly appealing if you like the idea of treating your hair with the same level of sophistication as your skincare.
Best for: Dryness, shine and a treatment-led luxury routine.
Why it stands out: It brings Augustinus Bader’s science-focused luxury positioning into haircare.
7. OUAI Hair Oil — Best for Everyday Smoothing
For something a little more effortless, OUAI Hair Oil is an excellent everyday option.
The current Sephora UAE listing describes it as a multitasking oil designed to smooth frizz, seal the appearance of split ends and create a high-gloss finish. It also includes ingredients intended to help protect the hair from heat and maintain colour.
This makes it particularly appealing if you want a product you can use regularly without making your haircare ritual feel overly formal.
Best for: Everyday smoothing, frizz and shine.
Why it stands out: It’s easy to incorporate into a normal styling routine while still delivering a polished finish.
8. Moroccanoil Treatment Original — Best Classic
There are newer products everywhere, but some formulas remain classics for a reason.
Moroccanoil Treatment Original has become one of the most recognisable hair oils in modern beauty, particularly for its versatility as a smoothing and finishing product.
It’s also currently available in the UAE through major beauty retailers.
For someone who doesn’t want an overly complicated routine, it remains a straightforward option for adding softness and shine.
Best for: Everyday smoothing, softness and shine.
Why it stands out: It’s a familiar, versatile classic that has earned a permanent place in many haircare routines.

How to Incorporate Your Hair Oil Into Your Routine
Once you’ve chosen your product, resist the temptation to use it simply because you own it.
Instead, give it a specific role.
A versatile oil such as Kérastase Elixir Ultime can work before styling or as a finishing touch.
A repair-focused formula such as K18 Molecular Repair Hair Oil can make more sense when damage and frizz are your main concerns.
A luxurious finishing product such as Sisley Precious Hair Care Oil can be reserved for moments when you want particularly soft, glossy-looking hair. Sisley specifically recommends applying it to the mid-lengths and ends of damp or dry hair.
This is where a luxury routine becomes personal.
You don’t necessarily need three different oils.
You need one that makes sense for your hair.
And if you’re building the rest of your beauty routine with the same philosophy, our The Ultimate Everything Shower Routine: Turn Your Shower Into a Luxury Ritual is a natural companion piece.
The Mistakes to Avoid
Even a beautiful luxury formula can disappoint when it’s used incorrectly.
Using Too Much
This is the easiest mistake to make.
Start with a small amount and increase only when necessary.
Applying It Everywhere
Unless the product specifically says otherwise, concentrate most oils and serums on the mid-lengths and ends rather than automatically applying them to the scalp.
Assuming Every Oil Protects From Heat
Don’t assume.
If heat protection is important to you, check the individual product’s instructions and claims.
For example, Kérastase Elixir Ultime specifically states heat protection up to 230°C, while K18 Molecular Repair Hair Oil lists protection up to 232°C.
Choosing Based Only on the Packaging
A beautiful bottle is part of the luxury experience, but it shouldn’t be the reason you choose the product.
Your hair should make the final decision.
Expecting Oil to Replace Haircare
An oil can improve shine, softness and the appearance of frizz.
It isn’t a replacement for cleansing, conditioning, treatments or sensible heat styling.
The most luxurious hair doesn’t look overworked. It looks healthy, soft, effortless and full of light.
That’s the finish worth aiming for.
Not hair that looks covered in product — but hair that simply looks beautifully cared for.
Make Haircare Part of Your Beauty Ritual
There is something particularly satisfying about giving haircare the same attention you give skincare.
Instead of rushing through every step, take a moment to consider what your hair actually needs.
Perhaps that’s a nourishing oil before washing.
Perhaps it’s a lightweight serum after a blow-dry.
Perhaps it’s one tiny drop through the ends before leaving the house.
The ritual doesn’t have to be elaborate.
It simply needs to feel intentional.
EDITOR’S NOTE
The most luxurious haircare routine isn’t necessarily the one with the most bottles. It’s the one that understands your hair.
If your lengths are dry, give them nourishment. If humidity makes your hair difficult to control, choose a smoothing formula. If heat styling or colour has left your hair feeling compromised, consider a treatment-focused product.
And when all you want is beautiful shine, remember that you probably need far less product than you think.
Luxury is often about restraint.

Final Thoughts
Glossy, healthy-looking hair doesn’t require an enormous collection of products.
The right serum or oil can be a small but transformative part of your beauty routine — particularly when you choose it according to your hair’s texture, condition and styling habits.
From the versatile Kérastase Elixir Ultime and repair-focused K18 Molecular Repair Hair Oil to the ultra-luxurious Sisley Hair Rituel Precious Hair Care Oil and the effortless OUAI Hair Oil, there are now plenty of sophisticated options available to UAE shoppers.
Start with less product than you think you need.
Apply it strategically.
And let your natural texture remain part of the look.
Because the most beautiful glossy hair doesn’t look like you’ve tried too hard.
It simply looks healthy, soft, polished and beautifully cared for.
