What It Is: Raincry's large-sized brush is used to smooth, polish and enhance shine. What It'S For: Ideal for long hair (past shoulders) types. What It Does: Made with 100% Pure Boar Bristles-no nylon. Raincry's Spiral Design increases the brushes' heating surface and channels air around the brush for less drying time and helps prevent snagging and damage. Only a pure Boar Bristle brush can provide the advantage of conditioning by transferring natural oils and product from scalp to ends. Raincry
