Definitions

  • the present invention relates to a process for cosmetic treatment, in particular for conditioning hair, using the combination of two distinct compositions, one being said anhydrous and the other being said aqueous, to the kit comprising said two compositions, and to said anhydrous composition.
  • conditioning agents in particular cationic surfactants, cationic polymers, fatty substances or silicones, to make hair easier to disentangle and to make them soft and supple.
  • conditioning agents improve the disentangling and softness of wet and dried hair, but may however have a tendency to make the hair lank and dull.
  • Hair care compositions such as rinse-off conditioners, and leave- on masks, creams and milks, are generally emulsions of varying degrees of thickness. They deliver good cosmetic properties to hair; however, users some- times feel that their hair is heavy and that it becomes greasy easily, especially if they have fine hair.
  • compositions with new deliv- ery forms that can be applied in a novel manner, or that can be prepared by the consumer directly, just before application.
  • the purpose of the present invention is to propose a kit, and a process for cosmetic treatment that is combined with it, that allows users to prepare their cos- metic composition themselves just before they use it; said cosmetic composition moreover having improved use properties and further delivering good hair conditioning properties.
