Davines | OI All in One Milk

What It Is:
A multitasking, hydrating hair milk that detangles, moisturizes and helps manage frizz while leaving the hair feeling weightless, smooth and soft.

How To Use:
Apply five to 10 sprays onto washed, towel-dried hair, and then style as normal. No rinsing necessary.

Editor Feedback:
“I’m super prone to frizz, but many of the more concentrated serums on the market are too heavy for my fine hair. This milky leave-in smooths without the extra weight.” —Britt Fallon, director of beauty

Key Ingredients:
Full of beta-carotene and antioxidants, the star ingredient is roucou oil, which strengthens hair and protects it against the effects of aging and environmental damage.
