An aqueous oxidizing compositions comprising one or more amino acids and hydrogen peroxide are described. The aqueous oxidizing compositions reduce hair damage during chemical services. The effect of hair damage reduction was found to be further improved when polycarboxylic acids were added to bleaching powder, oxidative dyeing, and permanent waving compositions.

A sulphate-free-surfactant cleansing composition comprising, in an aqueous continuous phase: a total amount of anionic surfactant and amphoteric surfactant consisting of: (i) from 3 wt % to 13 wt %, by weight of the total composition at 100% activity, of an alpha olefin sulfonate anionic surfactant of general formula (I): R.sup.1—CH═CH—CH.sub.2—SO.sub.3-M.sup.+ (I) in which R.sup.1 is selected from linear or branched alkyl groups having from 11 to 13 carbon atoms and mixtures thereof; and M is a solubilizing cation; (ii) from 1 to 8 wt %, by weight of amphoteric surfactant, which is cocamidopropyl betaine; (iii) from 0.05 wt % to 0.5 wt % of a cationic polymer; (iv) from 0.3 to 2.8 wt % an inorganic electrolyte; and (v) water; in which the weight ratio of (i) to (ii) ranges from 2:1 to 1:4 and the pH of the composition is from 3 to 6.5; and wherein the composition has a viscosity of from 2,500 to 25,000 mPa.Math.s, when measured using a TA Instruments Discovery Hybrid Rheometer; parallel 40 mm sandblasted plates, peak hold protocol at 4 s−.sup.1; at 30 oC.

A method for treating human keratin fibers such as the hair is described and comprises the application to the keratin fibers of a dye composition comprising at least one cationic acrylic copolymer and at least one pigment, and the application to the dyed keratin fibers of a makeup-removing composition comprising at least one hydrocarbon oil.

Provided are indigo darkener, containing: in parts by weight, 0.1-99 of indigo dye, 0-99 of alkaline dyeing assistant, 0.01-99 of acidic dyeing assistant, and 0-99 of oxidizing agent, and hair dyeing process using the indigo darkener. The multi-layer scales on the surface of hair are opened at large angles under alkaline condition and/or high-temperature condition, so that large indigo dyeing particles are easily absorbed in the scales; black indigo oxocarbon or carbon black is generated under the action of alkaline dyeing assistant and oxidizing agent at high temperature by the property that the indigo dye is easy to oxidize; the acidic dye assistant is added as the temperature decreases, and the scales having opening angles on the surface of hair are closed under acidic condition, so that the indigo carbide is firmly clamped and fixed in the scales of hair; finally, the blue indigo dyes white hair into black.
