What Is Davines OI Oil Used For?

Davines OI Oil is a multi-purpose hair oil created to improve the look and feel of dry, coarse or frizz-prone hair. It is mainly used to add softness and shine, reduce frizz, support easier detangling and give hair a smoother finish before or after styling.

So, what is Davines OI oil used for? It can be used as a pre-styling hair oil on towel-dried hair or as a finishing product on dry hair. Its lightweight texture allows it to smooth the lengths and ends without making hair feel heavy when the right amount is used.

The product is part of the Davines OI range, which is formulated with Roucou oil. According to Davines, the oil is particularly suited to dry or coarse hair, while it can also be used across other hair types with an adjusted quantity.

What Does Davines OI Oil Do for Hair?

Davines OI Oil works as a finishing and styling support product rather than a rinse-out conditioner or treatment mask. It helps manage the visible effects of dryness, such as rough texture, flyaways and dull-looking lengths.

Helps Control Frizz

Frizz often becomes more noticeable when the outer layer of the hair appears uneven or dry. Applying a small amount of oil through the mid-lengths and ends can help smooth the hair’s surface. This may make the hair look more polished and easier to manage throughout the day.

For people who use blow-dryers, straighteners or curling tools, a finishing oil can also be useful after styling. It helps tame flyaways around the face and gives the final hairstyle a neater appearance.

Adds Shine and Softness

One of the main uses of Davines OI Oil is to give hair a softer and shinier appearance. Hair that feels dry after washing, colouring or repeated styling may benefit from a light finishing product applied to the ends.

The oil is designed to leave hair looking glossy without creating a greasy finish. However, the amount used matters. Fine hair usually needs less product than thick, curly or coarse hair.

Supports Easier Detangling

Dry hair can catch and knot more easily, especially around the lengths and ends. Davines OI Oil can be applied to damp hair before combing or blow-drying to improve slip. This can make it easier to pass a wide-tooth comb or brush through the hair gently.

When detangling, start at the ends and work upward in small sections. This approach can help reduce unnecessary pulling and breakage.

Key Ingredient: Roucou Oil

Davines OI products contain Roucou oil, derived from the seeds of the annatto plant. Davines describes Roucou oil as rich in beta-carotene and antioxidants, with benefits linked to protecting hair from environmental factors and improving its condition. 

The product formula also contains ingredients that help create its smooth texture and provide a glossy finish. As ingredient lists may be updated, it is always sensible to check the packaging before use, particularly if you have known sensitivities or allergies.

How to Use Davines OI Oil

Davines recommends using the oil in two ways: before styling or as a finishing touch. The method you choose depends on your hair routine and the result you want.

Apply It Before Styling

After washing your hair, gently towel-dry it until it is damp rather than dripping wet. Apply two to three pumps of Davines OI Oil to the mid-lengths and ends, then comb through evenly. Continue with your usual blow-drying or air-drying routine.

If your hair is fine, begin with one pump. You can add a little more only if the lengths still feel dry.

Use It as a Finishing Product

On dry hair, place a small amount of oil in your palms and rub your hands together before applying it. Focus on the ends, dry sections and visible flyaways. Avoid placing too much product directly on the scalp or roots, as this may make the hair look flat or oily.

Davines advises two to three pumps for dry hair, while fine hair should start with one pump. 

Is Davines OI Oil Suitable for Every Hair Type?

Davines OI Oil is especially helpful for dry, coarse, thick or frizz-prone hair. These hair types may need more moisture and smoothing support through the lengths.

People with fine or straight hair can also use it, but they should begin with a smaller amount. One pump is often enough to add a polished finish without affecting volume. For curly or textured hair, the oil can be used after styling to smooth the ends and define the overall finish.

It is not a replacement for shampoo, conditioner or a deep-conditioning mask. Instead, it works alongside a regular haircare routine as a leave-in styling and finishing product.

Final Thoughts

Davines OI Oil is used to smooth frizz, add shine, soften hair and improve manageability. It can be applied before styling for easier detangling or after styling for a neat, glossy finish. Using the right amount for your hair type is the key to achieving a natural-looking result.
