Vibrating Scalp Handheld Massager Hair Brush https://www.amazon.com/dp/B01DTGUVVY/ref=cm_sw_r_em_awd_X2kjxb1W9QBP7
This massaging brush is battery operated with 2 AA batteries (not included). The way to install the batteries is to pull out the round red button on the handle and then pull down the top part of the handle to expose the inside of the handle and put your batteries in.
Once the batteries are installed and you put the handle back together, you can turn this brush on and start massaging your head. On the back side of this brush are little nubs that really make your scalp feel great.
This brush is not only a massager but also a great brush to use on a daily basis. The only complaint that I have with this product is that it has a strong odor.
I received this product for a discount for my honest unbiased review.
