1/2-inch long bristles
I had seen other reviews about the short bristles.  My hair, though long, is thin and fine, so I decided it would be ok.  As it turns out, the bristles really are just too short.  It takes extra work to brush properly to the scalp.  I love the feel of the brush...the nicely crafted wooden handle...the boar bristles.  With longer bristles, this would be a 5-star hairbrush.  If your hair is thin, fine, and short, then this is a great brush for you.
