Definitions

  • the present invention relates to a process for treating keratin fibers such as hair, as well as a composition and a kit to be used for the process.
  • compositions and/or processes known as treatments for repairing damaged keratin fibers that have been proposed are still insufficient insofar as they are often temporary and do not achieve proper recovery of keratin fiber integrity.
  • Fatty alcohols are known for their cosmetic properties on keratin fibers, and they are commonly used in hair care products. For example, please refer to US-A-2006-57096.
  • the main expectation of using fatty alcohols is generally to bring lustrous and shiny effects to keratin fibers.
