I initially loved this brush. It's pretty comparable to the Wet Brush, but feels nicer in hand and is slightly more flexible and easier on the hair.
However, after owning it for about a year, about 15% of the nubs have broken off, leaving sharp ragged plastic that scratches your scalp every time you brush. It hurts. Scalp health is the first step of hair health, so irritating my scalp with sharp edges is not on the menu.
I went back to my Wet Brush.
