Scalp massager

This is a scalp massager I got like two years ago and never used it at all because I couldn’t figure out how to and was to lazy to search it up. It’s apparently really good for all types of hair specifically curly hair to help with the natural oils in your hair and with washing it. Like I said it’s brand new, only thing that’s a little messed up is the packaging it came in. But other than that everything is included. Including the batteries and tool to open it.
