Conductive gel is specifically formulated to have a low resistance to electrical currents, allowing for efficient transmission of electrical signals between electrodes and the skin. It contains ingredients like sodium chloride or potassium chloride that help conduct electrical signals.
On the other hand, hair gel is primarily designed for styling hair and lacks the necessary conductive properties. Using hair gel instead of conductive gel can lead to poor signal transmission, affecting the accuracy and quality of measurements or treatments that rely on electrical currents.
