More specifically, the present invention concerns the inclusion of such compounds of formula I in hair dye compositions as direct dyes, and especially the novel compound 4-(2-hydroxyethylamino)-3-nitrobenzamide. The compounds, some of which are novel, provide a yellow dye base for the hair dyeing compositions.

Abstract: This invention relates to a multi-fluid mixing and automatic mettering dispenser for co-dispensing a pressurized permanent hair dye composition, having a first container containing a hair dye and propellant material, a second container disposed within the first container and containing a dye developer material, a nozzle structure defining a discharge passageway and a valve structure having first and second valves for controlling passage of the materials through the nozzle. The nozzle structure permits concurrent operation of the first and second valves to permit simultaneous flow of the materials form the first and second containers through the discharge passageway under the influence of the propellant, such that the materials exit from the dispenser at an overall flow rate not greater than about 1.8 gm/sec, and the flow ratio of the hair dye and propellant material exiting the first valve to the dye developer material exiting the second valve is in the range of about 1.9 to 2.5:1.

Abstract: A process for simultaneously cold waving and coloring hair in which the neutralization of the hair waving composition is accomplished in two stages, the second stage of which involves the use of a neutralizing composition containing a hair dye.

Abstract: In a method for oxidatively dyeing hair, a pretreatment which comprises contacting hair with an aqueous solution of an effective amount of particular metal/chelate complexes followed by treatment with oxidative dye mixtures is disclosed. The process serves to conform the oxidative dyeing rate of virgin hair to that of the normally noncongruent rate of nonvirgin hair, so as to enhance the efficiency of the oxidative dyeing process, without reducing the intensity or variety of color available.

Abstract: A bobbin or spool type hair curler having a cylindrical hair roller portion formed between a pair of opposing parallel flanges and provided with a pliable, integrally formed, cup-shaped closure member. The closure member is axially aligned to one of the end flanges of the spool shaped hair roller portion. The wall of the cup-shaped closure member extends away from the spool shaped portion and, after the hair is wound upon the spool shaped portion, the wall may be flipped substantially 180.degree. about its point of attachment to its corresponding flange in order to place the rim of the cup-shaped closure member proximate to the other flange to thereby retain the hair around the spool shaped portion. The invention additionally includes a method for curling hair with the aforementioned device and, in one embodiment the hair curler is provided with an axial throughbore and the invention further includes a method for heating same.
