Query: Nice Brush

I bought this brush because the boar bristles are supposed to distribute oils and grip hair better for blow drying. Sure enough, it works. I blow-dried my permed hair straight this morning in a matter of 50 minutes ( i have thick shoulder length hair that is semi-coarse). I was very pleased by the performance of this brush and I LOVE the nylon bristles. Some people may not enjoy their scratchy feel, but I am accustomed to brushing my hair with a metal bristle brush so I really liked it. The reason why I gave this brush four stars is because I question the quality of the brush...I had some little black bristles all over the floor after I was done blow-drying my hair and I know that another reviewer has had the same issue. I have never used another boar bristle brush before though, so I guess I can't really compare the quality to other brushes.
