Definitions

• Hairdressing tool hairdressing system and method for hairdressing
• the invention relates to a hairdressing tool, a hairdressing system and a method for hairdressing.
• Conventional hairdressing involves performing complex manual positioning techniques, such as manipulation, gathering, selection and/or separation, on a section of hair to prepare said section or underlying sections of hair for the actual hairdressing techniques, such as cutting, coloring, shaping and/or providing attaching hair extensions.
• Hairdressers are extensively trained to perform the positioning techniques with one hand while executing the hairdressing techniques simultaneously with the other hand. This limits the ability of the hairdresser to execute accurate and/or complex hairdressing techniques.
• the invention provides a hairdressing tool comprising a first mouthpiece, wherein the first mouthpiece comprises a suction inlet, a suction outlet, and a suction duct extending between the suction inlet and the suction outlet, wherein the suction outlet is connectable to a suction unit, wherein the suction inlet is arranged for sucking in a section of hair from the human head into the suction duct and wherein the suction duct is arranged for retaining said section of hair along a retaining path inside the suction duct wherein the suction inlet comprises an inlet opening with an inlet width and an inlet height, wherein the ratio between the inlet width and the inlet height is at least 10:1, preferably at least 15:1 and most preferably at least 20:1.
• the suction duct defines a laminar flow area extending from the suction inlet towards the suction outlet along the retaining path, wherein the suction duct at the laminar flow area is formed so as to generate a laminar or a substantially laminar flow of air along said retaining path.
• the suction duct has a cross section perpendicular to the retaining path, which cross section is constant or substantially constant in the laminar flow area. Hence, the air flow rate can be kept substantially constant in said laminar flow area.
• the inlet height is less than ten millimeters, preferably less than eight millimeters and most preferably less than six millimeters
