Our verdict

A weightless leave-in thickening spray for thin hair that wants body without stiffness. Volume figures in the listing conflict, so the bottle size is not fully clear.

Overview

People with thin, weak hair get a leave-in volumizing spray from Garnier that goes on after conditioning and stays in. Polypeptides and citric acid add body from root to tip without crunch or residue.

Fuller-looking hair after one use, with no stiffness, is the strongest case for this spray. The specs disagree on bottle volume, listing several different figures.

Who it's for

Fine hair that falls flat after drying suits this mist. People needing strong hold or heat protection claims will not find them here.
