I Tell Everyone I Know to Buy Davines OI All In One Milk Hair Mist

As someone with fine hair, this was my eternal dilemma: I needed a lightweight detangling spray that also hydrated my hair, but I simply didn’t think it existed. That is, before I tried Davines Oi All In One Milk.

The idea of spraying something called "milk" in my hair definitely felt weird (don’t worry, it’s not actually made from milk at all), but I heard so many rave reviews of the this product that I thought I’d give it a try anyway.

Luckily for me, it more than lives up to its purported detangling and smoothing claims.

The Bottom Line: Lightweight hydration

Davines Oi All In One Milk infuses hair with moisture without weighing it down—and it smells divine. It smooths frizz, detangles, and protects during heat styling, which makes it an all-in-one product ideal for taming and smoothing unruly hair.

About My Hair

As someone with super fine hair, fancy products always seemed to be a recipe for disaster. Hair masks would leave my locks weighed down. Sprays would make it greasy. Mousses or foams would leave it feeling crunchy.

But without products? My extra long, extra fine hair would get easily tangled, making it difficult for almost any brush to work through it comfortably. I’d have childhood flashbacks to when my mom used to try to comb out my tangled hair only to have me cry hysterically.

How to Apply

In my experience, the product is best used as the directions state—on damp, towel, or air dried hair. Simply give your whole head of hair 10-15 good sprays (although more is tempting given the smell) and either let it sit or run your hands through your hair like I do to make sure it covers everything. And that’s it. Your brush will run through tangles like they’re nothing at all, and your hair instantly feels hydrated and healthy without being greasy or weighed down.

If you have fine or short hair, you can probably get away with about half the spritzes. Spray mid-shaft through ends to distribute the product evenly and concentrate where you want the most hydration and silkiness.

The Feel: Light and fresh

This doesn't make hair feel greasy or heavy. It's a light spray that immediately softens hair.

The Scent: Soft and powdery

The first thing I noticed is the first thing everyone seems to notice when they use the cult favorite product (you should read the reviews): The smell. I instantly wanted to douse my whole body in the product and Googled to see if it came in a perfume or body wash version (it does, for $25), and looked forward to spritzing it on my hair each day. It's a light, floral scent that I love—sort of like the sweet scent of baby powder. It's also long-lasting and freshens up second-day hair.

Ingredient Quality and Concentration: Roucou oil

The brand touts its inclusion of roucou oil, or bixa orellana seed extract—an antioxidant-rich extract that comes from the annatto plant. Roucou oil is rich in beta carotene, which hydrates hair, and ellagic acid, thought to potentially bolster hair growth. However, it's the last ingredient listed, meaning the concentration in this product is low.

The Results: Silky and sweet-smelling

Even if the mist didn’t make my hair smell delicious, I’d still use it just based on how it makes my hair feel.

As someone who doesn’t spend a lot of time or money on cut, color, or heat styling their hair every day, having a product that makes my air-dried hair feel luxurious and healthy is worth every single penny. Even if the mist didn’t make my hair smell delicious, I’d still use it just based on how it makes my hair feel. Plus, it prevents frizz, a common enemy to my hair when it’s not blow dried or heat-styled.

The Value: Steep, but worth it

The one thing that might make you hesitate before buying this product? It’s not cheap. At $35 for 4.6 oz, it’s probably more than most of us spend on beauty products (especially ones that we may go through in a couple months or so). If I hadn’t received this in a PR mailing, I, too, probably would have been hesitant to add it to my cart. But now that I can’t live without it, I fully plan on purchasing it again and again and again.

Davines OI All In One Milk vs. It's a 10 Miracle Leave-In Product

At $19 for 4 oz, It's a 10's Miracle Leave-In is a cheaper alternative to Davines. Like the All In One Milk, Miracle Leave-In also contains panthenol and sunflower seed oil, plus amino acids to add moisture, strength, and shine. It detangles and protects during heat styling. You might consider It's a 10 if you have particularly dry, damaged hair—though there is a Lite version for fine hair.

Our Verdict: Memorable scent and magical results

If you read reviews, you’ll find people praising the product for everything from the way it tames their thick, curly hair to how it gets rid of their frizz for good. Some people even rave about how it detangles their hair and their grandchildren’s hair. And everyone—I mean everyone—talks about how good it smells.
