Shoppers Call This Multitasking Hairspray "Literal Magic" for Gray, Brittle Hair

We all have our passions, and for years, mine was pursuing the dream of silky, smooth, glossy hair — the strands that magazines once touted as the end-all, be-all. We're thankfully in a more inclusive place now, but I'll never forget convincing my parents to detour from a roadtrip to pick up a hard-to-find bottle of Davine's hair oil, convinced it would transform me (spoiler: It didn't). But according to shoppers, the brand's Oi All in One Milk is indeed "literal magic," especially for brittle grays.

The Italian brand has a few celebrity fans, including Connie Britton: She of the legendary mane told InStyle in 2018 that she was a fan of the line, and last year, Hailey Bieber highlighted the All in One Milk to Vogue. "With the time I spend swimming in the summer, it's important for me to always have a good leave-in conditioner handy to protect my hair and keep it knot-free. My go-to is the Davines Oi All In One Milk — [it] smells amazing and works great," the Rhode skincare founder said.

Thousands of other people are similarly impressed. The spray, which double-times as a heat protectant and detangler, has earned just under 7,000 five-star ratings at Amazon. One user with fragile gray hair called it a "game changer" for aging gracefully; their strands were left "stronger, thicker," and smelling fantastic, even in the face of significant damage.

Another shopper with gray hair dubbed the formula "great" for controlling frizz without weighing down their hair, an opinion seconded by someone who called it "literal magic" for their temperamental waves. Per a different person, it gives them a good hair day, every day — the only downside is the risk of strangers sniffing their hair (please, world, no). One more fan colorfully referred to the bottle's contents as "angel spit," since it leaves their color-treated, fly-away prone hair fabulously conditioned.

As luck would have it, no saliva is needed. The formula instead draws on panthenol, vitamin E, fatty alcohols, glycerin, sunflower seed oil, and roucou extract; the latter is an antioxidant and anti-inflammatory addition that the brand claims can offer anti-aging benefits, too. That said, it is last on the ingredients list, so it's difficult to say how much of those effects you'll notice.

Regardless, its hydrating and shine-inducing effect is undeniable. A penultimate user wrote that it "does wonders" for softening and smoothing out hair, and a last convert wrote that after trying it via a Birchbox sample, the decreased amount of breakage gave them longer, stronger hair. No wonder Reese Witherspoon included the product in the 2017 box she curated with the company.

If you'd like to try the Bieber-approved Davines Oi All In One Milk, get it for $36 at Amazon.
