Real boar hair shaving brushes are cheap and are packed with very stiff boar hair bristles. They are popular amongst those wet shavers who prefer to use hard shaving soaps when lathering up.
The boar hair is thicker and stronger than badger hair, but is much less softer, a boar hair brush needs worked in overtime to soften the tips. The stiffer backbone of the boar hair creates a lather from hard shaving soaps such as Mitchell’s Wool Fat, or tripled milled soaps such as Saponificio Varesino very easily.
Mixed hair shaving brushes cover a multitude of different, assorted grades of bristles. Typically a mixed hair brush consists of boar hair to give stiffness and backbone and lower grade badger hair, some even contain horse hair.
As with boar hair brushes mixed hair shaving brushes are much stiffer than standard shaving brushes so exfoliate the skin and lather up hard shaving soaps with ease.
