Definitions

  • the present invention relates to a cosmetic method of treating mammalian coloured hair to reduce or prevent colour fade and/or colour shift.
  • the colour be retained in a consistent manner for a predictable period of time. Further, there is a desire for the colour to be resistant to fading, as occasioned by the actions of washing (also known as wash fastness) and other exterior factors such as the action of the sun. It is, therefore, something of a balancing act between the desire to retain a consistent colour and the necessity of exposing the coloured hair to factors which would lead to colour fade and/or colour shift.
  • GB-1570220 discloses a pre-treatment composition comprising cationic materials for the elimination of the bad effect of discolouration or dyeing treatments.
  • JP- 60087208 discloses a pre-treatment comprising metal salts for preventing flux of protein components during shampooing and thereby protect the hair in addition to improving chemically damaged hair.
  • none of these references disclose the use of pre-treatment compositions on coloured hair for the prevention or reduction of colour fade/shift.
  • the present invention provides a cosmetic method for treating mammalian coloured hair to reduce or prevent colour fade and/or colour shift comprising;
  • the method can include treating the hair, after step (b), with a composition comprising a conditioning agent and/or an ultra violet filtering agent.
  • a composition comprising a conditioning agent and/or an ultra violet filtering agent.
  • the method of the present invention provides a reduction or prevention of colour fade and/or colour shift of coloured hair. The method can help to maintain a more consistent colour and, therefore, can increase the time between dye applications.
  • the method of the present invention comprises at least two essential steps, firstly a pre-treatment step and secondly a wetting step. Without intending necessarily to limit the scope of the invention, it is believed that pre-treatment with a composition comprising a conditioning agent 'seals' the hair thereby preventing or reducing the leaching out of dye molecules that can be caused by water.
  • coloured hair means hair which has been treated to alter its colour. In particular, this can be through a dyeing treatment which, permanently or temporarily, alters the hair's natural colour.
  • colour fade and/or colour shift means changes to the colour of coloured hair caused by the action of external conditions. In particular, this can be through exposure of the coloured hair to the sun or water.
  • reduction or prevention of colour fade and/or colour shift means impeding, retarding and/or arresting changes to the colour of hair. By reducing or preventing colour fade and/or colour shift a more consistent colour is achieved and the time between dye applications can be increased.
  • wetting of the hair means exposure of the hair to water.
  • this exposure can be during a cleansing regimen with, for example, shampoo or through other activities such as swimming.
  • a cleansing regimen it is preferable that such a regimen is carried out frequently, preferably from once a day to once a week, more preferably from once a day to once every three days, most preferably once a day.

Ce procédé peut éventuellement consister à traiter les cheveux, après l'étape (b), avec une composition contenant un agent traitant et/ou un agent filtrant les ultraviolets. Ce procédé permet de réduire ou d'empêcher l'affaiblissement des couleurs et/ou la dégradation de la couleur des cheveux teints. Ce procédé peut contribuer à préserver une couleur plus uniforme et, par conséquent, peut augmenter la période entre les applications de teinture.
