When people first discover the Davines OI range, they're often drawn in by the incredible softness, mirror-like shine, and luxurious fragrance. But behind every bottle is one remarkable ingredient that makes the collection so special – Roucou Oil.

Used throughout the entire Davines OI range, Roucou Oil is the hero ingredient responsible for the collection's famous ability to leave hair silky, radiant, and beautifully healthy-looking.

So, what exactly is Roucou Oil, and why has Davines made it the heart of one of its most iconic collections?

What Is Roucou Oil?

Roucou Oil is extracted from the seeds of the Achiote tree (Bixa orellana), a tropical plant native to the Amazon rainforest.

Sometimes called the "Lipstick Tree" because of its vibrant red seeds, the Achiote plant has been valued for generations for its protective and nourishing properties.

Davines carefully selects Roucou Oil because it offers exceptional cosmetic benefits for the hair while fitting perfectly with the brand's philosophy of combining nature with advanced cosmetic science.

Why Is Roucou Oil So Good for Hair?

One of the reasons Roucou Oil is so highly regarded is its naturally rich nutrient profile.

It contains:

🧡 Beta-carotene – naturally present at levels far higher than many common vegetables, helping to support healthier-looking hair.

🌿 Powerful antioxidants – helping to defend the hair against environmental stress and everyday aggressors.

✨ Vitamin A – helping improve the appearance of softness, shine, and overall hair condition.

Together, these naturally occurring nutrients help leave hair looking healthier, smoother, and noticeably more radiant.

How Roucou Oil Benefits Your Hair

Unlike heavy oils that can leave hair greasy or flat, Roucou Oil helps nourish without compromising movement.

Regular use of the Davines OI range helps to:

✨ Increase shine

💧 Improve softness

🌿 Reduce frizz

💙 Enhance manageability

🌬️ Speed up drying time

☀️ Help protect against UV exposure and environmental stress

Whether your hair is naturally healthy or in need of extra care, Roucou Oil helps improve the overall look and feel of your hair with every use.

Why Does Hair Feel Softer After Using the OI Range?

Healthy hair has a smoother outer layer, known as the cuticle.

When the cuticle lies flat, hair reflects more light, feels smoother to the touch, and becomes easier to detangle.

The conditioning ingredients throughout the Davines OI range work alongside antioxidant-rich Roucou Oil to help smooth the hair fibre, reducing roughness while improving softness and natural shine.

The result is hair that feels silky, looks glossy, and is easier to style.

Which Davines Products Contain Roucou Oil?

One of the reasons the OI collection works so well is that every product has been developed to complement the others.

It's one of the reasons the OI collection has become a favourite in professional salons around the world.

The OI Fragrance Everyone Falls in Love With
