According to Ayurveda, shirodhara is beneficial for Vata and Pitta dosha. When out of balance, Vata dosha exhibits as fear, insecurity, worry, racing thoughts. Out of balance Pitta dosha exhibits as anger, irritability, frustration, judgment.
The action and qualities of the liquid used in shirodhara counters the qualities of the out of balance doshas. It soothes, nourishes and pacifies the doshas through the application of the liquid to the forehead, scalp and nervous system.
