This is my fave brush. So much that I don't think you can see the number on the brush anymore. The only thing I don't like is that the hairs are white. I wish they were a dark color it bothers me that I can never make it as clean as you see in this photo again.
I just tried it on. First impressions I like it better than any other dry shampoo. Other dry shampoos make my hair feel a little sticky but not this one.
