Damage-free determination of the thickness of the main hair

摘要

There is provided a device (10) for determining the thickness of hair. The device has a computing unit (100) and a user interface (110). The arithmetic unit (100) has a processor (102) and a local memory (104), wherein the processor is connected to the local memory such that the processor can read data from the local memory and / or write to the local memory. The user interface (110) serves as an input unit and / or output unit for interaction with a user. The arithmetic unit (100) further comprises an image data input interface (106) for receiving image data of a hair ensemble consisting of at least a single hair, the image data input interface being connected to the processor, and a user interface (107) communicating with the user interface (110) and with connected to the processor. The arithmetic unit (100) is designed to process the image data of the hair ensemble and to thereby create a histogram of the hair thickness values occurring in the hair ensemble and to output the histogram to the user interface.
