Well, it depends. Sometimes manufacturers use a combination of fibers as well as horse hair and call it horsehair. Size is important, sorry male shoe brushes, as is the handle. How brittle or soft the hair is is also a consideration, depending on what you wish to do with it. There are many brands out there. Go to any higher end shoe store and they usually carry some good quality and reasonably priced brush. Around $20 is what I would pay.
