The present invention relates to a hair iron, and more particularly, to a hair iron which can perform a hair setting function using a single hair iron and a straight setting function capable of re-spreading the wave hair . In other words, in the hair iron, an assembly hole 111 is formed in the middle, and electric wires for supplying power are connected to the rear of the assembly hole 111 as a boundary, and a temperature control unit 112, A grip portion 110 provided with a grip portion 113 and a grip portion 114; A circular fixing part 120 having a first heating part 121 whose temperature is raised according to the operation of the first switch 113 is formed in front of the assembly hole 111; A handle 130 formed at a rear side of the assembly hole 131 and having an assembly hole 131 connected to the assembly hole 111 through a fixing means; And a circular swinging part 140 having a second heating part 141 whose temperature rises in response to the operation of the second switch 114 in front of the assembly hole 131. The first swinging part 141, By forming the first and second heating portions whose temperatures rise according to the operation of the first and second switches, it is possible to simultaneously set the wave setting and the straight setting of the hair so that the user can set the hair iron for hair setting and the hair for straightening It is possible to reduce the cost increase due to the purchase of the iron separately.
