In the method of hair color consultation, actual individual images of a person are continuously recorded by a video camera and are input into a computer in a continuous sequence in real time. Automatic image editing and processing is carried out in real time, in which the computer continuously marks hair regions of the individual images by an automatic analysis of close and similar pixel color values, of contiguous texture, and/or of contiguous morphological properties, and changes hair color of the hair regions according to predetermined specifications. Then the modified individual images with the changed hair color are displayed on the at least one screen and/or touch screen in real time so that the desired hair color may be selected. An apparatus for performing the method is also described.

Method for a hair colour consultation

Device () for the heat treatment of scalp hair () of a person (), consisting of one first and one second heat radiator (), which are formed and arranged facing each other as a left side radiator () and as a right side radiator () to provide heat () to the side scalp hair (), wherein the left side radiator () has one first ring-shaped infrared radiator () with one first shell ring reflector () and the right side radiator () has one second ring-shaped infrared radiator () with one second shell ring reflector (), wherein at least one third heat radiator () is provided for heat treatment of the remaining scalp hair, wherein all heat radiators () are arranged in a so-called open design to provide for unlimited handling and observation of the scalp hair () and extensive visual freedom for the person () during the heat treatment, characterized in that the first shell ring reflector () of this type has at least one first infrared radiation screen () and the second shell ring reflector () has at least one second infrared radiation screen () arranged as symmetrical mirror images and on the radiation side, and characterized in that radiation intensity () in the area of the contour () of an average hairline is gently reduced in the direction of the face () of the person () ().

Device for heat treatment

The handheld hair dryer for generating a heated air stream has a blower for generating an air stream, an electric heater for heating the air stream, a catalytic odor filter for deodorizing the air stream and a thermal radiator for heating the catalytic odor filter. The electric heater and the catalytic odor filter are separate from each other so that the active surface area of the catalytic odor filter can be maximized to deodorize the air stream. The thermal radiator is also separate from the electric heater.
