OI Oil Absolute Beautifying Potion — Reddit Reviews
by Davines
Updated November 5, 2026
Evaporating silicone shine serum for fine hair; featherlight, non-greasy, and pricey.
What the community says
An ultra-light silicone finishing serum that smooths frizz, adds shine, and layers easily without making fine hair greasy. Use a tiny amount on lengths and ends, especially if heavier oils flatten you; the strong lingering fragrance and premium price are the real deal-breakers.
