Staff Pick: OI All in One Milk

Best-selling and award-winning OI All in One Milk acts as both a daily routine and styling agent. Formulated with Roucou oil, OI products provide extraordinary shine and softness to any type of hair. Featuring a rich fragrance, with multiple benefits for your hair and skin, OI is made with antioxidant Roucou oil to protect hair against the effects of aging and environmental damage. Rich in beta carotene (which has a restructuring effect on the hair), Roucou oil reduces cellular damage from UV rays, as well as helping to prevent the signs of aging. Hair is instantly softer, detangled and therefore easier to comb to prevent unwanted breakage.


Lightweight OI All In One Milk is a multi-function leave-in spray treatment that softens, detangles, controls frizz and protects the hair from heat. Antioxidants for hydrating and shine-enhancing, for any hair type.

"This product is amazing for all hair types, and is a great prep product before a blow out. OI Milk is especially exceptional on colour treated hair. It’s very light and won’t add weight or greasiness. Makes hair easy to comb out and adds everyone’s favorite.... shine !!"

- Jenn, Senior Colour Technician

How to Use

Apply 10-15 sprays to washed, towel-dried hair. Do not rinse, and proceed with styling. It is possible to apply the product as a moisturizing finish, vaporizing it directly on the hands and then distributing it evenly on the hair, if they are particularly dehydrated.

Dedicated to absolute beauty for all types of hair and skin, the name OI comes from the ancient Eastern idea of harmony through the balance of opposite forces. In an effort to create balance between the senses, multiple benefits and effectiveness, OI lets you see immediate positive results from your first use. All products belonging to the OI family are both sulfate and paraben-free. The carbon dioxide emissions deriving from its production are offset with reforestation and woodland protection projects.
