Abstract: A hair processing accelerator which can uniformly irradiate heat to a hairline of the whole circumference of hair includes first and second heater units having first and second heaters of a generally semicircular shape connected to a top portion of a head top unit supporting part 3 which is positioned in the head top of hair. While moving through multiple positions and by swinging and rotating around hair so as to separate from each other to right and left or approach each other from right and left by a heater unit driving part 50 contained in a body supporting part 5, the first and second heater units irradiate heat to all the areas of hair from the head top of hair to each of right and left sides.
