Davines Oi All-In-One Milk, a leave-in hair treatment that has gone viral on TikTok, is winning over users with its ability to hydrate, detangle, and control frizz without heat styling. The lightweight spray has garnered over 10,600 five-star ratings on Amazon, with many reviewers calling it a "favorite ever" and a versatile product that keeps hair smooth even in humid or rainy weather.
What Makes Davines Oi Hair Milk Unique
Formulated for all hair types—from pin-straight to tight curls—the spray is designed to detangle post-wash and provide ongoing benefits like frizz control and protection from environmental stressors and heat styling. It can be applied to towel-dried or damp hair, or used after styling for a hydrating, flyaway-taming finish. The product also leaves behind a lasting fragrance, though those sensitive to smells may want to start with a small bottle.
The key ingredient is roucou oil, which the brand says is rich in beta-carotene and antioxidants that help strengthen hair. Davines uses this oil across its entire Oi line, including shampoos, conditioners, and hair butters.
Real User Reviews and Longevity
Despite a luxury price point, users report that a full-size bottle lasts at least six months, depending on hair length and thickness. One reviewer, Amanda U., shared: "I’ve been using this spray for 2 years... A full size bottle will last me a year. I have thick, long hair... Leaves my hair feeling so soft, moisturized, and shiny." Another user, J. Stechler, noted: "A little pricey but I get a good six months from one bottle and I find it well worth the investment."
Reviewers also highlight its effectiveness in challenging weather. Diane Rose said: "I have fine shoulder length hair and struggle with frizz on a good day. I have found if I use this product on a rainy or muggy day, my hair remains smooth. It is a must-have!"
Versatility for Curly and Coily Hair
Users with curly textures also praise the product. Nonya, who has dense coils, wrote: "This product does what it says and more. I use it as my leave in on dense coils and spray it on, let it sit for 1 minute, and my curls transform into lush, fragrant, moisture infused coils that a rat tail comb glides straight through!"
Another reviewer, Sarahsmile, noted that the product works well for thick hair without weighing it down: "I have really thick hair and I don’t like a lot of product since it weighs it down more but I don’t notice that with this."
