- Multi-Functional in One Spray: controls frizz, detangles, hydrates, heat-protects, and adds shine — replaces multiple products
- Heat Damage Protection: safeguards strands from hot tools up to 230°C / 446°F
- Effortless Detangling: instantly improves slip and combability, even on dense or tangled hair
- Weightless on Fine Hair: softens and conditions without weighing down or causing oiliness
- Long-Lasting Hydration: sustained moisture through the wash cycle for soft, manageable strands
- Distinctive Signature Scent: the cult-favourite OI fragrance, long-lasting and universally complimented
- Roucou Oil (Bixa Orellana Seed Extract): Amazonian heritage ingredient rich in beta-carotene, vitamin A, and selenium for antioxidant defence
- Panthenol (Pro-Vitamin B5): deeply moisturising humectant that draws and locks hydration into the hair shaft
- Functional Amino Complex: specialised blend that helps hair resist mechanical, thermal, and environmental stress
- Heat Protection up to 230°C / 446°F: shields strands from damage during blow-drying, flat-ironing, and curling
- Lightweight Spray Format: even, weightless distribution that won't flatten fine or medium hair
- 94.7% Naturally Derived Ingredients: vegan, cruelty-free, made in Italy
- Iconic OI Fragrance: complex sensory scent of thyme and pine, settling into musk and amber
- 1. Cleanse: Wash with OI Shampoo and condition with OI Conditioner for the full system effect.
- 2. Towel-Dry: Gently squeeze excess water from hair until it's damp, not dripping. The formula absorbs best at this stage.
- 3. Apply: Spray 10-15 pumps evenly across the mid-lengths and ends, focusing on the most frizz-prone or damaged areas. Avoid heavy application at the scalp.
- 4. Distribute: Run fingers or a wide-tooth comb through to ensure even coverage. Do not rinse.
- 5. Style: Proceed with blow-drying, hot-tool styling, or air-drying. Hair is now protected, detangled, and primed for shine.
- 6. Pro Tip: For dehydrated mid-day touch-ups, spray 1-2 pumps onto your palms, rub together, and smooth over dry hair to refresh shine and tame flyaways. For extra-frizzy or coarse hair, apply OI Conditioner first, then layer OI All In One Milk over towel-dried hair for double the moisture. The 50 ml travel size fits any carry-on — perfect for hotel stays, gym bags, and clients who refuse to be parted from it.
What is Davines OI All In One Milk used for?
Davines OI All In One Milk is a multi-functional leave-in treatment spray used to control frizz, detangle, hydrate, protect from heat damage, and add shine to all hair types. The lightweight formula combines Amazonian Roucou oil, Pro-Vitamin B5 (panthenol), and a functional amino complex to provide heat protection up to 230°C / 446°F while softening and smoothing the hair. It is applied to towel-dried hair before styling and is one of Davines' best-selling and most-awarded products, ideal as a foundation step in any styling routine.
Will Davines OI All In One Milk weigh down or make fine hair oily?
No, Davines OI All In One Milk is specifically formulated to be lightweight and is well-suited for fine, medium, and thin hair. The mist-spray delivery system distributes the formula evenly without saturating any one area, and the cream-serum texture absorbs cleanly without buildup. Reviewers with fine hair consistently report softness and shine without flatness, stringiness, or oiliness when used at the recommended 10-15 spray dosage on towel-dried hair.
Does Davines OI All In One Milk protect against heat damage?
Yes, Davines OI All In One Milk provides heat protection up to 230°C (446°F), shielding the hair against damage from blow-dryers, flat irons, curling wands, and other hot styling tools. The protection comes from a functional amino complex combined with the conditioning silicone film that forms when sprayed on damp hair. It does not, however, provide UV protection. For best heat-protection results, apply to towel-dried hair before any hot-tool styling and avoid maximum-heat settings when possible.

The product everyone ends up owning. Eventually.
Meet OI All In One Milk, Davines' multi-award-winning leave-in spray that has earned the kind of cult following most brands can only dream of. Read the reviews and you'll see the same pattern, over and over: "I've been using this for ten years." "My hair has never been this soft." "I won't switch to anything else." It's the product clients ask their stylists about by name — and the one stylists quietly buy for themselves.
The reason it works is the breadth of what it does. One spray controls frizz, detangles tangles, hydrates dry strands, shields hair from heat damage up to 230°C / 446°F, and adds the kind of weightless, naturally radiant shine that makes hair look professionally styled even when it isn't. It's powered by Roucou oil (Amazonian Achiote, rich in beta-carotene and vitamin A), Pro-Vitamin B5 for deep moisture, and a functional amino complex that helps hair resist mechanical and thermal stress. 94.7% naturally derived, vegan, and made with care in Italy.
The signature scent is the part that turns first-time triers into for-life buyers: a complex, sensorial blend of thyme and pine, settling into musk and amber. Lightweight enough for fine hair, hydrating enough for coarse, and a non-negotiable in every great blowout routine. Award winner — Strategist 100 NY 2026. A best-seller for a reason.
