New in gift bag. If your hair tends to fall flat, you’re in luck: The brand-new Living Proof Plump Up the Volume Discovery Kit features a curation of products designed to give hair 2x the volume in one wash**, add softness + shine, and provide both instant and long-lasting volume and texture. Full Shampoo + Conditioner, Perfect hair Day Healthy Hair Perfector, and Full Dry Volume & Texture Spray work together to make hair bouncy, fuller-looking, softer, and shinier. One of our hero ingredients at work is our patented Volumizing + Texturizing Molecule — found in Full Dry Volume & Texture Spray — which increases the space between individual hair fibers for long-lasting volume and texture that won’t weigh down hair. Amaranth peptides plump hair fibers for an instantly fuller look while a bio-based replenishing agent helps to repair hair’s outermost layer, known as the F-layer, to smooth the cuticle while amaranth seed extract replenishes hair’s lost natural lipids.
