Why we like it

The Moda Team Review

One product before the dryer that does five things: detangles, heat protects to 230°C, controls frizz, adds Roucou Oil softness, and primes for the OI Oil finishing step. The blowdry result is noticeably better than styling on unprotected hair. The product clients buy after the first appointment and never stop buying.

Read full stylist notes

The client who is getting a great OI result in the shower but blow-drying without any protection and wondering why the frizz comes back before she has finished styling. OI All In One Milk on towel-dried hair before she turns the dryer on — the frizz is controlled through the entire blow-dry and the finish looks salon-level. Davines is B-Corp certified, family-owned, made in Italy. OI All In One Milk is part of the award-winning OI line — the multi-function leave-in step that bridges the in-shower Roucou Oil conditioning into the blow-dry and styling phase.

How to use

Use it the way we would.

  1. Apply to towel-dried hair, working section by section from mid-lengths to ends.
  2. Comb or brush through to distribute evenly.
  3. Blowdry as usual — heat protection is active up to 230°C.
  4. Follow with OI Oil after blowdrying for the finishing gloss layer (optional but recommended).

Moda stylist tipApply to towel-dried hair section by section before blow-drying — not to dripping wet hair, which dilutes the Roucou Oil before it can bond. On fine hair, 3–5 sprays mid-lengths to ends is enough. On thick or long hair, 8–10 sprays working in sections for even coverage. Follow with OI Oil after the blow-dry for the full OI finish.

Best product I've tried for my fine curly hair. No more frizzy hair even when compared side by side with my previous long standing go-to. Love the signature fragrance as it's not too overpowering.

favourite davines product! the full size product is a small bottle but it surprisingly lasts a long time even on my very long hair. (although i do only wash 1-2 x per week and then use this product). I always repurchase.

Ask Moda
What does OI All In One Milk actually do — is it just a heat protectant?

OI All In One Milk does five things in one step: detangles, conditions, controls frizz, adds OI softness and shine, and protects from heat to 230°C. It is a multi-benefit leave-in that happens to include heat protection — and for clients who skip leave-ins entirely, it is usually the most impactful single product change we recommend.

Can I use OI All In One Milk alongside OI Oil, or is that too much product?

Using both is the routine we recommend for the full OI blowdry result. Apply the Milk to damp hair before blowdrying. Then apply 1–2 drops of OI Oil to dry hair after styling for the final glass-shine seal. They work at different stages and do not compete.

Is OI All In One Milk suitable for fine hair?

OI Milk is one of the lighter leave-ins we carry. Apply to mid-lengths and ends on towel-dried hair — not the root area — using 5–8 sprays for fine or short hair. Applying too much or too close to the roots is the most common reason leave-ins flatten fine hair.

Does OI All In One Milk work on curly or wavy hair?

Yes — OI Milk works well on wavy and curly hair as a pre-diffuse prep or for air-drying. It provides frizz control and softness without the hold of a gel. For fine wavy hair that wants body alongside OI softness, OI Soufflé is worth comparing.

How much OI All In One Milk should I use per application?

For short to shoulder-length fine hair, 5–8 sprays to mid-lengths and ends. For longer or thicker hair, 10–15 sprays, combed through for even distribution. Apply to towel-dried hair — not dripping wet — and do not rinse out.
