Abstract: A hair coloring apparatus comprises upper and lower hinged body parts closable about a lock of hair (58). Within the body parts is contained a drive mechanism and a color applicator (32) so that, when applied to a user's hair and closed, the apparatus moves progressively down a lock of hair (58) applying hair treatment material as it moves.

Abstract: An electrode generally comprises a body, which makes up the electrode and which is formed as a thin flexible polymeric substance such as urethane foam. The electrode body includes a central inner conductive area, which is associated with a first electrode connector. Around the inner conductive area is a non-conductive area formed as a ring around the inner conductive area and there is also an outer conductive area provided as a ring, concentrically arranged around the non-conductive area. Electrode connector (6B) is connected to the outer conductive ring. The electrode body, which has a release tag and is supported on a backing sheet and body can be peeled off the backing sheet using the release tag. The condition of the electrode can be evaluated using a test device, which can for example measure electrical impedance across the electrode via electrodes (6A) and (6B).

Abstract: A laser hair removal device 10 has a base unit 12 and a hand held laser wand 14. Laser 18 generates light pulses of sufficient energy and duration to damage papilla of each hair follicle in the path of the beam. The device 10 includes one or more safety features to prevent accidental misuse of the device. In particular, the device incorporates a high intensity LED 24 which makes looking at the potential path of the laser uncomfortable, thus promoting a blinking reflex. Additionally the device may incorporate a skin contact/proximity sensor 26 to prevent use of the laser away from the skin, and/or one or more locking element to prevent accidental powering of the laser.
