Davines OI Oil lightweight multi‑use hair serum — 4.56 fl oz, anti‑frizz & shine with roucou oil

Davines OI Oil is a lightweight, multi-tasking hair oil that smooths frizz, boosts shine, and replenishes moisture without weighing hair down.

Formulated in Parma with roucou oil and antioxidant-rich ingredients, this versatile hair serum works as a pre-styling protector, leave-in moisturizer, and finishing gloss for all hair types. The non-greasy texture absorbs quickly to detangle, protect from environmental stressors, and add a polished shine to dry, coarse, or color-treated hair. Available in a travel-friendly 1.69 fl oz and a full 4.56 fl oz bottle, Davines OI Oil is designed for those who want salon-quality softness at home.

How does Davines OI Oil control frizz and add shine?

OI Oil smooths the hair cuticle and creates a light barrier that reduces humidity-driven frizz while reflecting light for an immediate glossy finish. Its fast-absorbing formula leaves no heavy residue, so hair moves naturally and looks healthy.

• Contains roucou oil and antioxidants to seal and smooth the cuticle
• Light, non-greasy texture prevents stickiness or buildup
• Delivers instant high-shine finish without flattening volume

Can I use this oil on damp hair before styling?

Yes — a small pump on damp strands helps detangle, reduce drying time, and protect hair during blow-drying or heat styling. It primes the hair so styling tools glide easier and styling products perform better.

• Apply 1–2 pumps to mid-lengths and ends on towel-dried hair
• Helps reduce frizz while speeding up blow-dry time
• Compatible with thermal styling when used as a primer

Is this oil suitable for my hair type and color-treated hair?

OI Oil is formulated to be universal: it benefits fine to coarse textures by adding moisture and polish without excess weight. It’s also safe for color-treated hair, helping maintain shine and manageability while supporting hair health over time.

• Light enough for fine hair when used sparingly, richer for thick or curly types
• Color-safe formula preserves vibrancy and minimizes dulling
• Use more or less product to tailor effect to your hair density

How should I incorporate it into my routine for best results?

Depending on your goals, Davines OI Oil can be used pre-styling, post-styling, or as an overnight treatment. Start with a pea-sized amount, increase for thicker hair, and distribute evenly to avoid weighing down roots.

• Pre-styling: apply to damp hair to detangle and protect from heat
• Finishing: smooth a tiny amount over dry hair to tame flyaways and boost gloss
• Deep-conditioning boost: layer under a leave-in mask for added hydration

Who is this for: Davines OI Oil suits anyone seeking a lightweight, multi-function hair oil that tames frizz, enhances shine, and moisturizes without heaviness. Ideal for busy people who want quick detangling and styling benefits, color-treated hair that needs boost without buildup, and textured hair that needs definition and control.
