Davines OI Oil — Why We Can't Live Without It

If there is one product we recommend to virtually every client who sits in our chair at Yanni Hair Studio, it's the Davines OI Oil. It's become the kind of product that, once you've used it, you can't imagine not having. Not because it's trendy, but because it genuinely works — beautifully — on almost every hair type and texture.

What Is OI Oil?

OI Oil is a multi-benefit beauty treatment oil from Davines — the Italian BCorp haircare brand we stock exclusively at Yanni. It's a lightweight, golden oil enriched with roucou oil (a natural pigment from the Amazonian roucou plant) that provides protection, shine, detangling and nourishment in a single product.

The formula is silicone-free, which means it nourishes the hair without coating it in synthetic polymers. What you get is real, lasting improvement to the hair's condition — not just the illusion of it.

What Does It Actually Do?

• Adds luminous shine without greasiness or heaviness
• Tames frizz and flyaways throughout the day
• Detangles — makes combing damp hair significantly easier
• Protects from heat styling and environmental damage
• Softens the hair texture noticeably with regular use
• Works on all hair types — fine, thick, curly, straight, colour-treated

How to Use It Without Weighing Hair Down

The most common mistake people make with hair oil is using too much. OI Oil is concentrated and a little goes a very long way. For fine or medium hair, 1–2 pumps is usually enough. For thick or coarse hair, you might use 3 pumps on longer lengths. Always apply to the mid-lengths and ends first — never directly to the roots — and work through with your fingers before blow-drying or styling.

Application Methods

• On damp hair: Apply before blow-drying for heat protection and smooth finish
• On dry hair: Apply a small amount to tame frizz and add shine
• As a pre-shampoo treatment: Apply generously, leave 20 minutes, then shampoo
• Mixed with conditioner: Add a pump to your regular conditioner for extra nourishment

Why Davines?

We chose Davines as one of our two exclusive brands at Yanni Hair Studio because they align with everything we believe in. They're a family-owned BCorp from Parma, Italy — meaning they meet rigorous standards for social and environmental responsibility. Their ingredients are naturally derived and traceable, their packaging is sustainable, and their products are genuinely outstanding.

The OI range — which includes the Oil, Shampoo, Conditioner, Hair Butter and All-In-One Milk — is built around the concept of beauty rituals. When hair care feels like a ritual rather than a chore, you do it more consistently, and the results show.
