The Luxe Ingredients Breakdown

One of the many reasons Kérastase is so well-known is its curated formula. Here’s what is in this bottle:

Marula Oil – Packed with fatty acids and antioxidants, which are great for deep absorption and intense softness.

Camellia Oil – Lightweight and silky; provides shine and smoothness without greasiness.

Argan Oil – Moisturizing and protective; great for frizz taming.

Maize Oil – Possesses all of the key nutrients to help repair damage.

Pracaxi Oil – Being native to the Amazon, it helps boost shine and hydrate.

However, it’s also a selling point for the scent. Violet leaf, freesia, mandarin, and musk offer a deliciously luxurious scent that lasts for hours and smells like you’ve just stepped out of a salon.

How to Use Kérastase Hair Oil Properly

To get the most out of the Elixir Ultimatum, application technique is key:

  1. For a Pre-Shampoo Treatment: Add a few pumps on dry hair, leave on for 10-15 minutes, and shampoo as you would normally for deep nourishment.
  2. On Damp Hair Before Blow-Drying: Use 1-2 pumps in mid-lengths and ends to provide heat protection and improve smoothness.
  3. As a Finishing Oil: Rub a teaspoon amount between palms and lightly sheer it over styled hair for instant shine and the control of flyaways.
  4. As an Overnight Treatment, generously use before heading off. For deep absorption or if hair is damaged or bleached.

FAQs

Does Kérastase Hair Oil make hair greasy?
A: Not if you don’t overload the hair. Use only 1-2 pumps on the ends. Kérastase hair oil can make your hair limp as it is very nourishing, especially for fine textures.

Can I use it every day?

Yes! It’s so lightweight that you can technically use it every day, but make sure it’s along with your usual routine. Kérastase hair oil is not going to build up on your hair unless you are really overusing it.

Is it color safe?

Yup! Kérastase hair oil is ideal for color treated hair because it nourishes and protects the hair.

Is there a dupe for Kérastase oil?

There is not exactly a dupe for Kérastase oil! The complex oil blend and scent is so good! On a budget, L’Oréal Extraordinary Oil or OGX Renewing Argan Oil are decent, but those will not replicate the same as Kérastase oil.

How often should I use Kerastase oil?

You can use Kérastase hair oil daily or a few times a week, depending on what your hair needs. To control frizz and add shine, a little amount on damp or dry hair after styling will do. To nourish dry and damaged hair, once or twice a week I would recommend a pre-shampoo treatment. Fine hair can benefit from 2-3 times a week of Kérastase oil, but thick and/or dry hair can benefit from using it daily.

Is Kérastase good or bad for your hair?
Kérastase is very good for your hair when used correctly, its products contain high-quality ingredients – such as marula oil, argan oil, and ceramides – that will nourish, protect, and repair your hair. Kérastase is particularly effective if you have damaged hair, dry hair, color-treated hair, or frizzy hair. Just keep in mind that it is possible to use too much Kérastase, especially if you have very fine hair or oily hair.

Is Kérastase high quality?
Kérastase is a high-quality, luxury haircare company that is used by professionals and salons all over the world. Kérastase has a long history of scientific innovation, and provides some of the best quality ingredients available on the market. Kérastase is also sought-after for its impressive salon-like results. Kérastase tends to be relatively pricey compared to other brands, however, many users believe that their hair health and visible shine are worth the investment!
