The styling step of the Acidic Grow Full system for thicker-looking hair
Redken Acidic Grow Full Instant Densifying Spray is a leave-in spray for fine, thinning-looking hair and a key step of the Acidic Grow Full system. It gives an instant boost of up to 17% in volume and lifts the roots for fuller-looking hair, while protecting against heat styling up to 230°C. It adds body without weight and leaves hair soft, smooth and easy to style, never greasy or heavy.
How it works
A light mist that you spray on damp hair, focusing on the roots, before blow-drying. It dries without stiffness or residue, so hair keeps its movement.
Who it suits
- Fine hair that falls flat
- Hair that looks thinner at the roots
- Anyone who blow-dries or uses hot tools
- Users of the Acidic Grow Full shampoo and conditioner
Worth knowing before you buy: the effect is cosmetic and instant: it makes hair look thicker and fuller while you wear it. For a routine that targets the scalp and hair fall over time, pair it with the Acidic Grow Full anti-hair loss treatment.
