Many shoppers search oil non oil by mistake. The product line is called OI. Searching the right name finds the real listings faster.
Choose size by commitment level
New users should start with the 1.69 oz travel size. A little goes a long way. Commit to the 4.56 oz bottle once you love it.
Check it is the real OI Oil
Look for the Davines store as seller. The bottle should say OI Oil with roucou oil. Fakes exist, so verify the listing carefully.
Dose by hair thickness
Fine hair needs one to two drops. Thick hair can take three to four. Start small and add more only if ends still look dry.
Use it before heat styling
OI Oil doubles as a light heat protectant. Apply to damp hair before blow drying. It speeds drying time and boosts shine.
