Density Thickening Protein Spray contains unique hyper-branched polymers and hydrolyzed pea peptides to instantly volumize fine hair. The heat-protecting, density-boosting formula fortifies weakened strands, helping to preserve the internal structure of the hair, while improving luster and shine.

- Hyper-branched polymers increase volume by transforming from a flat structure on wet hair, to a hexagonal shape upon drying, pushing the hair apart to deliver lasting volume and healthy hair ​
- Hydrolyzed pea peptides increase strand thickness and provide hydrating and smoothing benefits for the hair
- Panthenol is a conditioning agent that provides long-lasting moisture, thickens, and improves luster and sheen ​
- Yeast extract creates a protective layer over the cuticle, to protect against thermally induced damage
