Introducing Oi Shampoo

The Colour Bar Salon Owner and Master Stylist, Lorena Martinez, talks all about the beloved Davines Oi Shampoo—you’ll learn why it’s our top-seller and why we can’t stop recommending it!


Loved by thousands of people around the world!

Makes my hair feel so soft and clean!

This shampoo has been amazing! It smells great and makes my hair feel so soft and clean. It brings volume to my roots and my hair does not feel greasy for about 2-3 days. I love pairing this shampoo with the conditioner. You do not need a lot of product to get the job done, so it is worth it.

Doesn’t weigh down my hair!

I have baby fine, color treated hair. This shampoo locks in the color, doesn’t weigh down my hair while making it soft and smooth. Paired with the OI All in One Milk, my hair has body and holds the style after blow drying. Love it!

This product is consistently amazing every time!

My hair is very long (below my hips) and I struggle to find products that I like for more than 2 washes. This product is consistently amazing every time I use it. I was SHOCKED when it worked better than anything I owned. It lathers extremely well, it feels clean the instant I run my fingers through to the end, and it leaves my hair shiny and weightless.

I will never use another shampoo again!

I am NEVER one to leave review but I love this product so much that I thought it deserved it. Ever since I switched I have been getting so many compliments on how healthy, shiny, and amazing my hair looks and I don’t even need to blow dry it anymore. I will never use another shampoo again... 10/10 love love love this product.

Amazing for my type 4C hair!

After receiving a sample of this product I became curious about how it would react with my type 4C hair. It was AMAZING and I quickly went to purchase more of both the shampoo and conditioner. It's a little pricey so I don't purchase as frequently as I'd like but it is definitely worth the money. Please try if you have coarse or kinky hair!

Your hair has never looked this good before!

A+++++ Shampoo and the OI smell is amazing. Shampoo leaves your hair clean and shiny and smelling delicious. Your hair has never looked this good before.

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.
