In various embodiments, a hair treatment device is provided. The hair treatment device can have a device body, at least one sensor arranged in or on the device body for detecting a hair condition parameter, and an electronic circuit device arranged in or on the device body. The electronic circuit device can be coupled to the at least one sensor for receiving the detected hair condition parameter, and the electronic circuit device can be configured, based on the received detected hair condition parameter, to control at least one hair treatment parameter and/or to dose at least one hair treatment agent and/or to provide a hair treatment recommendation.

Hair treatment apparatus, hair treatment system and method for cosmetically treating hair

A packaging system for a multi-component product preparation process, having: a first container for storing a first product preparation component, a second container for storing at least one second product preparation component, and a closure element which seals off the first container from the surroundings and has a coupling device in order to couple the second container to the closure element and in order to establish a fluidic connection between the first container and the second container. The closure element includes a closure cap which can be separated from the closure element along a predetermined breaking point in order to release the fluidic connection between the first container and the second container, wherein the closure cap can be coupled to the second container—so as to be blocked in a rotational direction about an axis of the closure element and movable in a direction parallel to the axis.

Packaging system and method for multi-component product preparation processes

A hair condition-determining device can have a device body having at least one first region and one second region, wherein the first region and the second region are designed in such a way that the hair of the user can be moved between the first region and the second region, at least one optional light source arranged in or on the device body for illuminating the hair of the user, at least one optical sensor arranged in or on the device body for sensing light that has been emitted by the light source and has interacted with the hair and/or ambient light that has interacted with the hair, and an electronic circuit device arranged in or on the device body, wherein the electronic circuit device is coupled to the optical sensor in order to receive the detected light.
