OI All in One Milk | Hair Leave-in Conditioner Spray | Powerful Hair Detangler + Hydrating Leave-In Treatment | Smoothes Frizzy Hair

I discovered the Davines Oi line about 11 years ago and this was one of the first products I started using. I’ve never looked back and have continued to use this for over a decade. Occasionally I’ll try a different leave in conditioner because I get drawn in by marketing but I have never ever found anything that even comes close to being as good as this! I always go right back to it. It’s so lightweight but really set angles and provides a lot of nourishment and shine, it helps protect against heat damage and seems to speed up my blow dry time, I also like using a small amount on dry hair for 2nd day re-styling and it’s great for that. It truly cuts down on frizz and static. The scent is incredible, it’s like nothing I’ve ever smelled before; just really warm and comforting but it’s so subtle and would not be overwhelming for anyone who is sensitive to scents. A little goes a long way (one of the small bottles lasts me just shy of a year and I have thick medium length hair) so it’s worth the cost. It’s perfect for normal hair and dry and damaged. I really can’t recommend this enough! No oily feeling just smooth, sleek, and silky! Just buy it, you won’t regret it!

This product is pure magic in a bottle. It makes my hair feel unbelievably soft, hydrated, and manageable without weighing it down. I spray it on damp hair after every wash, and it instantly detangles, smooths, and adds the most beautiful shine. My hair feels like silk once it dries — soft, bouncy, and healthy-looking. The scent is rich, clean, and salon-level luxurious — it lingers just enough without being overpowering. I have long, thick hair and only need a few sprays, so the bottle lasts a long time. It also helps protect my hair from heat styling and keeps it smooth even in dry air. Every time I use this, my hair looks freshly blow-dried and glossy, even if I let it air dry. It’s one of those rare products that lives up to the hype and then some.

My favorite leave in conditioner to moisturize my hair! It works so well and leaves my hair shiny and soft. I have long hair and use ~5 sprays throughout then brush it through. It has a nice subtle smell and the bottle lasts until the product is gone. This is also a pretty clean product and made it Italy- so love these aspects as well.

I’ve been buying this product for years, and it’s truly one of my all time favorites. If you knew me, you’d know I’m very sensitive to smells, most hair products are so strong they give me a headache or make my skin break out around my hairline. But this one? It’s the total opposite. The scent is soft, clean, and heavenly when you spray it, and the best part is that once your hair dries, the fragrance fades away. 🌿💫 ✨ Scent note: The smell is light, fresh, and slightly floral with a soft powdery base, kind of like a subtle, high end salon perfume. It’s not sugary or fruity, just clean and elegant. If strong fragrances usually bother you, this one is gentle and fades beautifully as your hair dries. The formula itself has been consistently amazing through every bottle I’ve bought. I have thick, wavy hair with tons of volume but very fragile, thin strands, not exactly the easiest combination to deal with. And living in a state with very harsh water doesn’t help either. This product cuts through all of that. All I need is a Wet Brush and about 5 or 6 sprays, and my hair instantly feels soft, smooth, and completely tangle free. No heaviness. No greasy film. Just healthy, shiny hair that behaves like it had a good night’s sleep 😄✨ 🌿 Ingredient & origin note: This leave in is made in Parma, Italy, where Davines formulates and produces everything in their own labs. It’s powered by roucou oil, packed with antioxidants and beta carotene to help protect and strengthen hair, along with panthenol (pro-vitamin B5), vitamin E, and sunflower seed oil to soften and hydrate. While it does contain a light fragrance and some smoothing agents, I’ve never experienced any irritation, the scent stays soft, not overwhelming. 💡 Helpful tip: I’ve found that applying it to damp hair and then brushing through once distributes the product perfectly. No need to overdo it. A little goes a long way, which makes this luxe product last a surprisingly long time. I’ve tried other leave ins over the years, but nothing else has worked this well while being gentle on both my skin and senses. This little black bottle has earned its permanent spot on my bathroom shelf and I’ll keep repurchasing it again and again 🖤

Not sure how I stumbled across this most excellent product, but many reviews talked about how good it smells... so i started with the smaller travel size to test it out. And yes, it *really* works well on my fine hair, and smells soooo good. The first day I kept wondering what perfume I had on, then remembered that I had used this on my hair. Not that you're wafting around in a cloud of scent, but it's just very pleasant. Kind of woodsy but fresh, easily a uni scent (I also love Maison Louis Marie's Bois de Balincourt perfume, not that it smells like that, but it's kind of the same direction). My hair feels silky and bouncy (no frizz!), although one day I went enthusiastically overboard with the spray and it was all a little flat. Live and learn. I also love that it comes in a travel size and full size –– I will just refill the small one from the larger size so I can take it with me on adventures. I've already signed up for a subscription because I never want to be without this lovely product.

I spray this on my hair when I get out of the shower and it really helps to detangle it a bit more after towel drying, so that it's easier to comb through. I love the smell of it and really like the product itself - it's not heavy and it sprays evenly. I do think it's expensive for the size of the bottle - $45 for just 4.6oz is not ideal - but again, I do really like it and it helps keep my hair healthy.

I have been looking for a leave-in spray for my hair; I have very fine hair, so finding a nice product that doesn't weigh my hair down has been difficult. Firstly, this smells amazing! Makes my hair feel so smooth and my hair isn't greasy at all after a whole day. I'm a big fan. Its a bit pricey, but I do think its worth it for the quality.
