Enter OI by Davines: a sleek, sensorial product line that pairs Italian craftsmanship with plant-powered science for your most radiant hair and skin yet.
At Bloom Beauty & Extension Co., we’re constantly testing and curating products that match our high standards for performance, clean ingredients, and sustainability. OI has more than earned its place on our shelves — and we’re excited to show you why.
Whether you’re a blonde preserving shine, a brunette taming frizz, or someone who just wants touch-ably soft hair and nourished skin, the OI line offers daily indulgence without excess. Keep reading to explore how it works, which products to try, and how to experience its benefits at home.

What Makes OI So Special?
The OI line is built around Roucou Oil, a golden botanical extract from the Amazon, rich in beta-carotene, antioxidants, and essential minerals like selenium. Known for its anti-aging and restorative properties, Roucou oil protects hair and skin from environmental stress, UV damage, and free radicals — all while restoring softness, elasticity, and vibrancy.
Unlike harsh or heavily perfumed salon products, OI delivers a sensorial experience with subtle, fresh fragrance and rich textures that melt into the hair and skin. And with Davines’ signature commitment to sustainability, every bottle is made with recycled materials and carbon-offset production, so you can indulge without compromise.
OI Product Breakdown: Your Routine, Reimagined

OI Shampoo
This award-winning shampoo is where the magic begins. Its milky formula gently cleanses while smoothing and softening strands from the very first wash. With Roucou oil as the star ingredient, it’s perfect for those who want volume, shine, and manageability without sulfates or residue.
Best for: All hair types
Tip: Follow with OI Conditioner for a complete care experience.

OI Conditioner
Buttery, rich, and impossibly hydrating, this conditioner is a dream for anyone who wants detangled, soft, and silky hair without the weight. It also helps speed up blow-drying and protects from mechanical stress — making styling easier and gentler over time.
Best for: Medium to thick or dry hair
Tip: Rinse thoroughly and follow with All In One Milk or OI Oil.

OI All In One Milk
The name says it all — this do-it-all leave-in spray delivers moisture, detangling, heat protection (up to 230°C/446°F), frizz control, and enhanced shine. It’s lightweight but powerful, and great for prepping hair for a smooth, sleek blowout.
Best for: Fine to medium hair
Tip: Mist onto towel-dried hair before styling.

OI Oil
This multi-use oil adds softness, definition, and a mirror-like shine to any hair type. It’s especially helpful for taming frizz and reducing blow-dry time. Use it before styling for protection, or after to polish and perfect.
Best for: Coarse, frizzy, or thick hair
Tip: Start with 1–2 pumps on damp hair, adjusting based on density.

OI Hair Butter
Think of this as a weekly wellness ritual for your hair. This nourishing mask melts into strands, leaving them softer, smoother, and easier to manage. The best part? It’s versatile: use before shampooing, after, or both for a deeper treatment.
Best for: Dry, damaged, or frizz-prone hair
Tip: Use on dry hair pre-wash, then again after for an intensive repair boost.

OI Liquid Luster
A water-like, weightless rinse-out treatment that transforms hair in just one use. The high-gloss effect is immediate, with silkiness and shine amplified — perfect before a night out or a self-care reset.
Best for: Dull, coarse, or tired hair
Tip: Use after shampoo, before conditioner. One to two doses is plenty.

OI Soufflé
New to the OI family, this light styling foam gives fine to medium hair body, shine, and bounce — without stiffness. It also provides heat protection, making it a great blow-dry prep.
Best for: Fine, flat, or limp hair
Tip: Avoid the roots and use sparingly; this formula stretches far.
OI Body Wash & Hand Balm
OI isn’t just for your hair. The OI Body Wash creates a creamy lather that cleanses without drying, while OI Hand Balm offers deep hydration with a silky, non-greasy finish. Both are perfect for a calming end-of-day ritual — or a luxe start to your morning.
