This volumizing shampoo and conditioner duo uses Biovolume 128™, a linden bud–derived ingredient, along with hydrolyzed rice protein and biotin to lift fine, flat hair from the root for a fuller, bouncier look.
Unlike heavier formulas that sacrifice hydration for volume, this pairing balances lightweight moisture with strand-strengthening ingredients, so hair looks fuller without feeling weighed down. In a survey of users, 90% saw increased hair volume after 28 days of consistent use.
