Dark Oil.
A lighter touch.

We love hair that looks polished and still wants to move. Meet the Sebastian Dark Oil family—and the thoughtful routine behind that smooth, touchable finish.

Shine is a detail we care about. So is movement. The finish we love at OLETTE has polish, but you can still see the haircut, the texture and the person wearing it. Sebastian Dark Oil fits that mood beautifully: a collection built around smoothness, shine and a lightweight feel.

We use and love Sebastian Professional in salon. When we recommend a product, our starting point is the finish you want to recreate—not the number of bottles in the range. Dark Oil is a useful example of why knowing each product’s role makes a routine feel simpler.

Start with the care.

The family includes a shampoo, conditioner and mask. These are the rinse-out steps: cleansing, everyday conditioning and a more intensive conditioning option. Sebastian positions the range around silky shine and smoothness, while the mask brings deeper nourishment.

Our approach is to choose the amount of care your hair actually needs. If your lengths feel dry but your roots lose volume easily, tell us. If you love a smoother blow-dry but still want body, make that part of the brief. The right recommendation should respect both the look and the feel you enjoy.

Polish you can see.
A finish you still want to touch.

The oil is the finishing detail.

Dark Oil Smooth & Shine Styling Oil can be used on damp or dry hair. Sebastian recommends one to two pumps, concentrated through the mid-lengths and ends. It is designed to help smooth frizz and add shine without a heavy, oily finish.

For us, placement is the useful part of that advice. Ask your stylist to demonstrate the amount for your own length and density, and where to begin applying it. A product that works beautifully through long, dense ends may need a lighter approach on a shorter, finer cut.

Mist, serum or oil?

They are different tools. The Silkening Hair Mist adds a light veil of shine. Taming Elixir is a smoothing serum with heat-styling protection, used through damp hair before styling. The Styling Oil is a smoothing and shine step for damp or dry lengths.

We would not treat the oil alone as a substitute for a dedicated heat protectant. Choose protection that is appropriate for the tools and temperatures you use, and follow its directions. Your stylist can help you separate the prep step from the final polish.

Why we love this kind of routine.

It gives you options without asking you to use everything at once. You might need a well-chosen wash routine and one styling step. You might prefer a little finishing oil on the days you blow-dry, and a different approach when you wear your natural texture.

We also love making the recommendation tangible. At your appointment, ask what created the finish and what you would need to reproduce it. A clear demonstration is more useful than a long list of products with overlapping jobs.

Make it yours.

Dark Oil is for a finish, not a hair colour: the name does not mean it is only for brunettes. Bring us your questions about softness, shine, flyaways or a blow-dry that feels weighed down. We will help you decide which parts of the Sebastian range belong in your routine—and which you can leave on the shelf.
