Kérastase's Elixir Ultime L'Huile Original Hair Oil Is the Secret Sauce to My Fine Hair Care Regimen

The Kérastase's Elixir Ultime L'Huile Original Hair Oil is a blend of five precious oils that promise to add shine and prevent breakage. Our editor shares how it’s her savior for split ends.

I don’t know about you, but anything dubbed as a “magic potion for beautiful hair” is a must-try in my book. Enter: the Kérastase Elixir Ultime L'Huile Originale Hair Oil. This elixir has been name-dropped in countless beauty articles as the best hair oil for its frizz-zapping abilities and powers to soothe split ends. It was about time I did my due diligence as an editor at—one who deals with both these concerns—and put it to the test.

My ideal hair has a glossy finish that mimics that of a glazed donut. In reality, I haven't been able to stick with a decent hair routine in ages, so my locks lack vibrancy and are sprinkled with split ends. I also recently learned that my super fine hair has high-porosity and therefore doesn’t hold moisture as much as I’d like, leaving me with lots of frizz by mid-day.

Read on for my Kérastase Elixir Hair Oil review and see if it lived up to the hype for me.

The luxurious blend helps to prevent breakage, making it the ideal oil for dry hair and split ends.

It’s a multi-use product that can be used before, during, or after you blow-dry your hair for a boost of nourishment. It can be used on all hair types, but promises to work wonders on over-processed hair and dull hair looking for shine.

Is Kérastase Elixir Ultime Heat Protectant?

Yes, Kérastase Elixir Ultime L'Huile Originale Hair Oil can be used as a heat protectant! To use pre-blowout, apply to towel-dried hair and blow dry as you normally would.

Is Kérastase Elixir Oil Worth It?

This Kérastase Elixir is more than just a nourishing oil for hair. Considering this product’s versatility—it can be used to smooth frizzy and split ends, as an oil treatment pre-wash, heat protectant, and works for touch-ups, too—it’s the best oil for hair and well worth the price tag. Not to mention, 3.4 fluid ounces is a lot more product than most bottles of hair oil house.


My Kérastase's Elixir Ultime L'Huile Original Hair Oil Review

I admit, I had my apprehensions about using oil for hair, especially on hair as fine as mine. I stopped using hair oils a while ago when the formulas I found left my hair greasy and stringy, and not glazed donut-like. But the Kérastase Elixir quickly became my summertime hair favorite. It sits on my desk while I work from home to smooth out any flyaways before video calls, and I’ve even been throwing it in my beach bag since it’s the perfect solution to quench thirsty strands soaked with salt. And now that we’re transitioning into fall, it’s keeping my ends intact when I heat style.

Let’s count the other ways I’ve used the iconic elixir: to slick down baby hairs, to finger curl tendrils, to swipe over any signs of frizz, to scrunch into my waves so they look less crispy and more shiny…the list goes on.

Just two to four drops emulsified into my palms does the job when I’m distributing across my entire head, but the pump dispenser makes it easy to go for just a drop when using for touch-ups. Honestly, it’s a game-changer versus the dropper bottles commonly used for hair oils. Plus, the formula leaves no residue behind.

For all these reasons and its truly weightless formula, Kérastase Elixir Ultime L'Huile Originale Hair Oil has made me a hair oil convert. I can say without a doubt that as far as the ‘best hair oil’ for fine hair title goes, this is it.
