Searching for how to use Kérastase Elixir Ultime oil usually comes down to one worry: how much is too much? Hair oils have a reputation for leaving fine hair flat and greasy when overdone, and for doing very little when underdone. The good news is that the product pages for the Elixir Ultime serums give a clear, simple method. In this guide we walk through that method step by step, explain how the Original and the Rose version differ, and show where a different finishing oil might suit you better.
A note on how we write about this. House of Portofino is an independent reseller and not an official dealer for Kérastase or any other brand we list, and we are not affiliated with or authorized by them. We describe what each product page says and keep to shine, softness and styling. We make no health or treatment claims.
What Elixir Ultime is, in plain words
The Kérastase Elixir Ultime L'Huile Originale hair serum is described as a lightweight leave-in serum for different hair types. Its listed aims are to nourish, to smooth and to add shine. The page says it helps the look of dry or frizz-prone hair and leaves the lengths soft and manageable. It is formulated with marula, camellia and argan oils, and is designed to avoid a heavy or greasy feel. The size listed is 100 ML.
Two points matter for how you use it. It is a leave-in, meaning you do not rinse it out. And it can go on before or after styling. That flexibility is the reason it suits both a quick morning routine and a longer blow-dry session.
How to apply it, step by step
The usage instructions on the page are brief and sensible. Here they are in order, with a few practical extras from us that are common hair-care sense rather than product claims.
-
Start with a very small amount. The page says to apply a small amount and adjust to your hair length, texture and styling needs. With oil, you can always add more but you cannot take it away.
-
Choose damp or dry hair. The page says it can go on either. Damp hair makes it easier to spread; dry hair is better for a quick finish.
-
Focus on mid-lengths and ends. That is where hair is usually driest and where frizz tends to show.
-
Spread evenly. Warm the oil between your palms, then smooth it down the lengths. A wide-tooth comb can help distribute it.
-
Style as you like. The oil can go on before or after styling.
Keep it away from the roots
The page points you to the mid-lengths and ends, and we would keep it there. Applying oil near the scalp is the most common reason hair looks flat by lunchtime.
Adjust for length and texture
A short cut needs far less than long hair. If your hair is fine, start with the smallest amount and see how it behaves after drying. If it is thick or coarse, you may want a little more on the ends. The page does not give a fixed number of pumps or drops because the right amount depends on you.
Original or Rose: which one?
The two serums are close relatives, and the difference lies in who they are for. The Kérastase Elixir Ultime L'Huile Rose Serum is described as a lightweight leave-in serum designed for colored hair. Its formula lists Imperial Tea along with the same marula, camellia and argan oils. The aims on the page are similar: nourish the lengths, add softness, smoothness and shine, and help frizz look less visible without a heavy or greasy feel. It is also 100 ML.
In short:
-
Original: described for different hair types.
-
Rose: described for colored hair, with Imperial Tea added to the formula.
If your hair is colored, the Rose is the version the product page is aimed at. If it is not, the Original is the more general option.
Another route: an oil for lightened or blonde hair
If your concern is dryness after lightening, a different product may be closer to what you want. The Kérastase Huile Cica-Gloss 100ML strengthening hair oil for blonde hair is described as a nourishing hair oil for dry, lightened or colored hair. The page says it is meant to help hydrate while adding softness, smoothness and shine, with a lightweight texture. It is enriched with Edelweiss extract and comes in a refillable pack. The application advice is the same as for the serums: a small amount on the lengths and ends of dry or damp hair, spread evenly, then style.
The product title uses the word "strengthening". We would not read that as a promise; the description itself speaks of hydration, softness and shine, and we suggest you read the full page for yourself.
For fragrance lovers: a perfumed finishing oil
A fourth option is the Chronologiste Huile de Parfum 100ML: Luxury Perfume Oil for Hair. This one is described as a scented hair oil that adds softness and shine and leaves hair subtly perfumed, with notes of tea rose, light woods and musk. It contains myrrh extract and goes on as a few drops on dry or towel-dry hair, mid-lengths and ends, with no rinsing. Note that the size shown in the variant is 75 ML.
A simple routine you can try
- Wash and towel-dry your hair as usual.
- Apply a small amount of oil to the mid-lengths and ends.
- Dry and style as normal.
- If the ends still look dry, add a tiny amount more on top once the hair is dry.
Give it a few uses before deciding. Hair that looks too oily on day one often just needs a smaller amount on day two.

Common mistakes with hair oil
-
Starting at the roots. Oil belongs on the lengths and ends. Roots tend to look flat quickly.
-
Using too much on day one. Start with a tiny amount and build up over several washes.
-
Applying to very dry, tangled hair. Comb through first so the oil spreads evenly instead of sitting in knots.
-
Changing everything at once. If you change shampoo, styling tools and oil in the same week, you will not know which one made the difference.
Storing and using it
The pages do not give storage instructions, so follow the printed guidance on the packaging when it arrives. As a general habit, keep the cap closed after each use and avoid touching the pump head to damp hands, so the product stays clean.
FAQ
Can I use hair oil on wet and on dry hair?
The Elixir Ultime pages say the serum can be applied to damp or dry hair, concentrating on the mid-lengths and ends. Dry hair is good for a quick finish; damp hair makes it easier to spread.
Will it make fine hair look greasy?
The pages describe a lightweight texture designed not to feel heavy. Even so, any oil can weigh fine hair down if you use too much or apply it near the scalp. Start with very little on the ends and add only if needed.
Do I rinse it out?
No. The Elixir Ultime serums are described as leave-in products, and the Chronologiste oil's page explicitly says not to rinse it out.
