“Happy is definitely an understatement. The happy hairbrush cleaner worked with all the different bristle brushes I own! ( Hard and soft ) Within 20 seconds each brush was as clean as the day I got them. I'm never going back to the old way of wasting my time using a comb that barely picked up anything. Idk maybe I did it wrong. Anyway... I'm seriously happy with my order and I may get a happy hairbrush in the future when I'm in the need for a new brush.”
