Circling: Place the teeth on the scalp and wiggle small circles in one direction, then reverse with the same number of circles in the opposite direction. Stroking: Brush (stroke) one direction, then reverse. If you have fine or thinning hair, be extra gentle or opt for the other two techniques. Tapping: Just like it sounds — gently tap the teeth of your tool along the targeted area.
