I bought the ionic shower head and beads 6 months ago. I noticed a huge improvement in the condition of my hair. Before then I found it very difficult to brush my hair, despite having quite straight hair. My brush would stick in the lengths and break the hair even with plenty of conditioner. Once I started using the ionic beads, it was easier to brush, in better condition, thicker. My hairdresser asked me what I had done to improve the condition.
I'll admit too that I did purchase other cheaper beads online but they just set my hair back again and once I purchased these beads again my hair improved more.
