Definitions

  • the invention relates to a package kit for a tint, the kit comprising at least a first, a second and a third container, and a method for dyeing a substrate using the package kit of the invention.
  • the hair strands will comprise root virgin hair or new growth hair which has not been previously coloured and conversely at the tips hair which has experienced one or multiple hair colouring treatments.
  • the tips of the hair typically are the most damaged portion of the hair and the colour will have changed over time dependant on the wash fade profile and number of types of hair colorant applied, amongst many relevant factors.
  • the intermediate hair length is typically a medium between these two extreme conditions.
  • the salon stylists typically will colour the root virgin hair first with a specific composition to most effectively colour the hair to the desired end result.
  • the remaining length of the hair and tips which has been previously coloured and may have undergone multiple colouring cycles is coloured with a separate and different composition to that applied at the roots.
  • the salon stylist aims to provide a homogenous end colour result along the entire length of hair from root to tip independent of the variations of starting hair colour and condition along the hair length.
  • the tint used in a hair dye is susceptible to oxidative influences, especially to molecular oxygen found in the air.
  • Many successful attempts have been made to shield the tint from such influences, e.g., by using metal tubes or specific laminates or plastic packs which can essentially eliminate the contact between the tint and the oxidative environment.
  • Most of these attempts result in a serious disadvantage for the user insofar, as they require a transfer of the tint into a developer solution by the end user.
  • the solutions involving plastics for producing a tint container involve blow molding techniques, which severely restricts the options for the design of the container.
  • the present invention relates to a package kit for a hair dye comprising
  • the invention further relates to a method for dyeing a substrate having at least a first zone and a second zone with the first zone and the second zone having different properties, wherein a package kit as described above is provided, the first composition comprising a developer, the second composition comprising a tint and a third composition comprising a modifier, the method comprising the steps of
  • hair to be treated may be "living” i.e. on a living body or may be "non-living” i.e. in a wig, hairpiece or other aggregation of non-living keratinous fibers.
  • Mammalian, preferably human hair is preferred.
  • wool, fur and other keratin containing fibers are suitable substrates for the compositions according to the present invention.
  • dyeing composition it is meant a composition suitable for changing the color of hair.
  • the dyeing composition is referred hereinafter as “the composition”, unless otherwise specified.
  • the dyeing composition can comprise oxidative dye precursors, direct dyes or even no, or substantially no, dyes in case of bleaching only compositions where the change of color is mainly caused by the degradation of the natural melanin contained in the hair shaft by the oxidizing agent.
  • the term “dyeing" composition as used herein covers hair bleaching and hair oxidative dyeing products.
  • the dyeing compositions are applied to hair which has already been previously dyed with dyeing compositions.
  • the terms "root”, “hair roots”, “root hair line” and “virgin hair” all refer to the portion of hair having grown, since the last dye, said portion of hair being virgin, i.e. naturally-coloured and the terms “hair lengths and tips” refer to the remaining portion of hair having been already previously dyed.
  • All percentages are by weight of the respective compositions, i.e. of the dyeing composition or the first, second and third composition, unless otherwise specified.
  • the total weight to be considered is the total weight of the mixture of the necessary compositions applied on the hair simultaneously (i.e. the weight found "on head"), typically resulting from mixing a developer composition (also oxidizing composition/component) with a tint composition (also called dye composition/component), unless otherwise specified. All ratios or percentages are weight ratios or weight percentages unless specifically stated otherwise.
