Badger hair has the firmest bristles, which makes it ideal for eyebrow brushes, fan brushes, bronzer brushes and for grooming. Badger hair typically comes from China and is similar to sable hair in the sense that it has a thicker middle and a thin top, tapering out into a conical shape.
High-quality badger hair has a light and dark brown color, while lower-quality badger hair is gray and is commonly found in shaving brushes. Although badger hair is extremely firm, it is also very soft and has an elastic quality so it will never scratch up your face.
This Shu Uemura Natural Fan Brush ($45) is a popular brush used for powder and liquid face color. It's great for blending and dusting with accuracy. Keep in mind that because badger hair is so soft and bouncy, it must be kept clean at all times.
