Abstract: The invention relates to a two-chamber container in which two separate components are to be mixed together to make a ready-to-use preparation before it is dispensed from the container, and which are contained in two chambers, an upper container and a lower container chamber, disposed one above the other in a container housing. The container chambers are connected to one another by a passage running from the top of the lower container chamber into the bottom of the upper container chamber. A separating plug stops this passage. The plug can be displaced into one of the container chambers by a plunger element which can be displaced in a vertical direction from the outside, so that the components can flow together and be mixed with one another within the container.

Abstract: A mixture for the oxidative dyeing of human or animal hair, which is prepared immediately before application by mixing an oxidant and a dye base in cream, gel or powder form containing at least one oxidative dye and adjusting to a pH in the range of 8.0 to 10.5.The means contains in the freshly-prepared state a microencapsulated, acid-reacting compound in an amount which shifts the pH of the dye into the weakly alkaline (pH.ltoreq.8), neutral or acid range.The encapsulating material for the acid-reacting compound is soluble in the alkaline dye or changeable at least in its strength properties in the sense of a weakening, the wall thickness of the microcapsules being so adjusted that the walls are dissolved or weakened within a period between 10 and 60 minutes to such an extent that the acid-reacting compound is able by itself or upon the exertion of an additional mechanical stress to emerge into the dye.Furthermore, the invention relates to the use of the means for the redyeing of dyed hair.

Abstract: The permanent shaping agent containing one or more hair keratin-reducing active substances is adjusted by means of stiffening additives to a consistency that is viscous to cream-like at room temperature with a viscosity of over 100 mPa.times.s.The stiffening additives are selected such that the permanent shaping agent, upon warming to a temperature with a temperature range between 25.degree. and 42.degree. C., undergoes a decided loss of viscosity of over 60% with respect to the initial viscosity, to a value under 50 mPa.times.s, i.e., becomes fluid within this temperature range.The permanent shaping agent of raised viscous or creamy consistency is applied to curled hair on curlers and then the viscosity of the permanent shaping agent is lowered, by elevating its temperature in situ, so that the liquified agent penetrates into the hair on the curlers.
