Not only does this mousse give fine strands a major dose of volume without any crunch, but it also provides heat protection and repairs strands so they feel stronger over time. The color-safe formula contains panthenol to plump up your hair shaft to add thickness, while a structure-forming starch polymer and styling polymer provide flexible hold and memory so your look lasts all day. With other conditioning ingredients like sunflower seed oil, glycerin, and vitamin E, it feels soft to the touch.
