1. Usage: The finger ring comb is small, easy to carry and operate, and can be used for head massage anytime and anywhere. Meridian combs need to be massaged accurately according to the direction of meridians, otherwise the expected effect will not be achieved.

2. Relieve stress: By massaging the head, the ring comb can relieve the stress and fatigue of the head and promote relaxation and sleep. Because the meridian comb is highly irritating, it is not suitable for some special people, such as pregnant women and hypertensive patients.
