  • Patent number: 5042987
    Abstract: Hair on a live head is treated with metal ion in a pretreatment step then subjected to an oxidative or autooxidative dyeing step in which scalp staining occurs. Between the pretreatment step and the dyeing step the scalp of the live head is subjected to vigorous massage, rubbing, combing or brushing for a time sufficient to reduce scalp staining, or sufficient time is permitted to elapse between the pretreatment step of the dyeing step to reduce scalp staining, or a combination of these two procedures is employed.

  • Patent number: 5034014
    Abstract: An aromatic amine, or a cosmetically acceptable salt thereof, is reacted with an aromatic aldehyde in a reaction medium containing water. 2,6-dihydroxypyridine, or a cosmetically acceptable salt thereof, is reacted with hydrogen peroxide in a reaction medium containing water. The two reaction mediums are combined so that both reactions are carried out together on hair. Preferably, the two reactions are carried out together in the same reaction medium. pH is adjusted so that the pH of the common reaction medium is about 5 to 7. Surprisingly, substantially no cross reaction occurs between the two reactions on hair.

  • Patent number: 4399349
    Abstract: An electrically heated, hand-held portable facial sauna appliance has a top air inlet, side air inlet, an air flow adjustment arrangement and a fan to mix ambient air with steam generated from a quantity of water contained in an internal steam generating chamber having an associated electric heater and a bottom fill opening such that the appliance must be inverted to fill the chamber with water. A water trap and overflow arrangement in the container ensures that the chamber cannot be overfilled and enables the appliance to be overturned during use without leaking. The appliance is provided with attachments in the form of a facial mask, concentrator tube, brush and sponge, each designed to fit over a steam-air mixture outlet and control the quantity of air entering through the top air inlet.
