Why does a scalp massage feel so good?
There are 7 pairs of nerves that end on the scalp. These nerve endings are connected to larger nerves, which ultimately connect to the brain. The nerve endings pick up messages from the skin being touched and send them to the brain, and the brain interprets them as pleasure, pain, or other sensation.
In Chinese medicine, several meridians cover much of the scalp. A scalp massage stimulates these meridians, which cover large portions of the body.
Either using Western science or Eastern tradition, the scalp is a sensitive place, and these scalp massagers work fantastically!
