## Abstract

A hairdressing device is designed to heat a hair at different temperatures. The device includes first and second arms coupled together by a hinge so that the arms can be closed together when pressed toward each other, each of the first and second arms including a grip portion and a head portion extending from the grip portion. The first arm includes a first heat generating body having at least one electric heater arranged in the head portion for heating a hair. The second arm includes a second heat generating body having two electric heaters arranged side by side in the head portion for heating the hair at different temperatures and a digital display part provided on an outer surface of the second arm for indicating information on a permanent to be performed.

## Claims

### Claim 1

A hairdressing device comprising first and second arms coupled together by a hinge so that the arms can be closed together when pressed toward each other, each of the first and second arms including a grip portion and a head portion extending from the grip portion,
wherein the first arm includes a first heat generating body having at least one electric heater arranged in the head portion for heating a hair, and wherein the second arm includes a second heat generating body having two electric heaters arranged side by side in the head portion for heating the hair at different temperatures and a digital display part provided on an outer surface of the second arm for indicating information on a permanent to be performed.

### Claim 2 (depends on 1)

The hairdressing device as recited in claim 1, wherein the electric heater of the first heat generating body of the first arm includes first and second ceramic heaters arranged in a parallel relationship with each other and wherein the first arm has a plurality of vapor suction holes formed at a generally equal interval between the first and second ceramic heaters.

### Claim 3 (depends on 2)

The hairdressing device as recited in claim 2, wherein the two ceramic heaters of the second heat generating body of the second arm include third and fourth ceramic heaters arranged in a parallel relationship with each other and wherein the second arm has a diode unit provided between the third and fourth ceramic heaters.

### Claim 4 (depends on 3)

The hairdressing device as recited in claim 3, wherein the diode unit includes a plurality of laser diodes for irradiating laser beams on the hair and a plurality of infrared diodes for emitting infrared rays toward the hair, the laser diodes and the infrared diodes arranged alternately along the third and fourth ceramic heaters.

### Claim 5 (depends on 3)

The hairdressing device as recited in claim 3, wherein the first and third ceramic heaters are designed to heat the hair in a temperature range of 200° C. to 250° C., and the second and fourth ceramic heaters are designed to heat the hair in a temperature range of 55° C. to 75° C.

### Claim 6 (depends on 1)

The hairdressing device as recited in claim 1, wherein the electric heater of the first heat generating body of the first arm includes a single ceramic heater and wherein an ion generator is provided on an inner surface of the first arm for generating negative ions.
