Introducing Oi Oil

The Colour Bar Salon Owner and Master Stylist, Lorena Martinez, talks all about the cult favorite Davines Oi Oil beautifying potion—how to use it, why we love it, and why you need it.


Loved by thousands of people around the world!

I love it and would recommend this beauty for anyone!

The Davines Oi Oil has been a traditional hair care product for me and has never disappointed! I use it either after a shower with damp hair or after straightening or curling my hair, this has helped repair and shine my damaged hair throughout use. I love it and would recommend this beauty for anyone!

The best thing that's happened to my hair!

I was referred to this product by a salon owner. It's been the best thing that's happened to my hair. I've colored my hair for a long time and it was pretty damaged. I had been using Moroccan Oil but never noticed a difference. This stuff changed my hair so quickly. I've been using it over a year now and my hair feels so healthy and like I never color it. My hair is fine and this product never weighs it down or makes it feel greasy.

This stuff is weightless!

I have heavily highlighted hair that is fine and straight. This stuff is weightless, soaks into the shaft of the hair, and you need only a dime-sized amount to work through your hair. The price may be off-putting to some, but it lasts FOREVER.

The scent never gets old!

I have used Oi Oil for around 5 years or so now! Great after showers on wet hair, for styling/finishing dry hair, and to moisturize the ends of my dry, fine, highlighted hair in the morning and at night. All this usage and it doesn't weigh my hair down or leave it greasy, plus the scent never gets old. Love.

Must have for my thirsty curls!

I have been using the OI Oil for several years and I always make sure that I reorder it as soon as my bottle is a little low. This product is a must have for my thirsty curls. After using it, my curly hair looks shiny without feeling greasy. This is a staple product in my hair routine and I will continue using it for years to come! :)

I can’t live without it!

I don’t even have the words to describe how magical this oil is. Not only does it smell good, but it really nourishes your ends (especially when they’re prone to split ends and drying). I use this along with Nounou shampoo+conditioner and Oi Milk. I can’t live without it and I must have it at all times!

I'm obsessed!

I have become obsessed with this product. It adds great shine, reduces frizz and doesn’t feel greasy. I like the scent too.

About Davines

In 1983, Davines was founded in Parma, Italy as a research laboratory that focused on high-end hair care production. Davines spent over a decade experimenting with different formulas for other companies, and eventually decided their expertise could be put towards their very own line, so they did just that. The Davines group now has Davines hair care, founded in 1992, their beloved skincare line Comfort Zone, founded in 1996, and further expanded with Skin Regimen in 2018.
