We've been using the Knot Genie for several weeks now with my 3-year-old daughter, and I've been pleasantly surprised with the results. She still cries when I first mention that I'll be brushing her hair, but then after I start to brush it with the Knot Genie she stops crying! It's a wonderful relief to finally find a product that keeps her hair detangled and stops all of that fussiness. Not to mention that her hair is silky smooth by the time I'm done brushing. I highly recommend this product if you are looking for a high quality hairbrush for your daughter...or yourself!
