Abstract: A hair treatment composition, particularly a hair colouring and/or bleaching composition, comprising an oxidizing agent, an alkalizing agent selected from the group consisting of ammonia, its salts and mixtures thereof, one or more fatty alcohol(s), one or more non-ionic surfactant(s) and a specific fatty compound. It is also provided a kit, method and use thereof. Superior hair treatment performance, particularly superior colouring and bleaching performance, with a reduced or an eliminated smell of said alkalizing agent upon application, is achieved.

Abstract: A composition for providing a film on keratin fibres comprises: an aminosilicone polymer; a silicone resin which is a MQ resin; a thickening system comprising a thickening polymer; and a solvent. The composition has a viscosity of from 30 mPa·s to 1000 mPa·s, wherein the viscosity is measured at 23° C. The composition has a tangent delta of less than 2 at an angular frequency of 1 Hz at 23° C. and at 1% strain. Also, associated methods, kits and uses are provided.
