• a smooth hairstyle meets practicality criteria, being easier to maintain than a hairstyle with volume, as well as fashion criteria, since many people with long or medium hair prefer it.
• a smooth hairstyle gives a neat appearance to the hair, and this with less effort to do on the part of the user than to obtain a puffy hairstyle.
• the methods for straightening the hair, initially curled naturally or artificially, consist mainly of mechanical or thermal actions on the hair.
• the known methods for straightening the hair can be either cold or hot, so they imply the use or not of heat during the straightening.
• the device described essentially comprises a clamp with two articulated arms, the inner surface of which comes into contact with the hair is covered with an absorbent material, soaked in a solution to make cold perms.
• the wick to be treated is immobilized in the forceps, the forceps are closed by a lock, its tip being wound around a roller made of an absorbent material.
• the roller is then fixed in the clamp fixing ears, at a predetermined distance from the latter so as to stretch the wick and process it in this position.

The wicks thus first combed are then brought into contact with the metal parts facing the teeth of the comb. The hair is then straightened while being held between two fixed heating flat surfaces.
• Such an accessory is described in document US 3,939,850.
• This accessory has the shape of a comb fixed perpendicular to the longitudinal axis of the device, at the outlet end of the blown air. Using such a device, the hair is first combed, tensioned by the comb and dried in this stretched position.
• Another type of hair dryer accessory is described in document US Pat. No. 5,553,632. It performs shaping by penetrating inside the hair, lifting the hair and drying it in this same position. It consists of a comb secured to the upper part of the blower nozzle. The comb has two rows of overlapping teeth and means for moving one row of teeth relative to the other. In operation, the teeth of the comb penetrate into the hair, grasp it and retain it to allow it to exert traction on it when the hair dryer moves, the hot air sent by the hair dryer drying it in this position, near the root.
• the object of the present invention is to overcome the aforementioned drawbacks by proposing an accessory for hair straightening which is effective, quick and easy to use and which at the same time respects the treated hair.
