Japanese head spa treatments improve the condition of your scalp. The massages that are part of the treatments help reduce stress and prevent hair loss. One of the major causes of thinning hair and hair loss is blood circulation deteriorating from the stiffness and dryness of the scalp. It also comes from the regular stresses of life. Scalp massages reduce shoulder tension and scalp stiffness and can relieve stress, eye strain, and brain fatigue.
