Abstract: A two-part oxidative dyeing composition is described. The two-part composition has an alkaline first part comprising oxidative dye couplers and/or oxidative dye precursors, and a second part comprising hydrogen peroxide, xanthine and/or its derivatives, and a lipophilic compound. The second part is formulated as water-in-oil emulsion and it was unexpectedly found that xanthines stabilize the viscosity of the second part composition allowing for improved dyeing performance.

Abstract: Processes and kits for permanent waving keratin fibers achieve durable shiny waves. The processes comprise treating fibers with a reducing composition, a non-reducing and non-oxidizing alkaline composition, optionally and acidic composition and finally an oxidizing composition, wherein, after processing the reducing composition, the fibers are rinsed off and the fibers are inserted into a curler having a tubular body with a first opening located at the first end and a second opening located at the second end and, wherein the curler is configured to allow keratin fiber streak to be inserted from the first opening toward the second opening and it is capable of being rolled up.

Abstract: 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.

Abstract: An aqueous oxidizing composition comprising a xanthine derivative is described. The composition may comprise more than 5% by weight of hydrogen peroxide. The composition may further comprise a lipophilic compound or a surfactant, and may be applied to keratin fibers. It has been unexpectedly found out that xanthine derivatives stabilize hydrogen peroxide compositions during storage.

Abstract: A hair treatment method for curling a lock of hair using a hair holder. The hair holder includes a tubular body which has an opening located at a first end and an opening located at a second end of the tubular body, and configured to allow a lock of hair be inserted from the first end opening of the tubular body toward the second end opening and to be capable of being rolled up. The method includes inserting a lock of hair into the hair holder, rolling up the tubular body together with the lock of hair inserted therein, so that the number of turns of the lock of hair is less than one, and curling the lock of hair in this wound state. A hair holder in which the tubular body is configured to be wound less than one turn is suitably used in this hair treatment method.

Abstract: The present invention provides a hair treatment method for curling a lock of hair (H) using a hair holder (1). The hair holder (1) includes a tubular body (2) which has an opening (21) located at a first end of the tubular body and an opening (22) located at a second end of the tubular body, and which is configured to allow a lock of hair (H) to be inserted from the opening (21) toward the opening (22) and to be capable of being rolled up.

Abstract: A hair treatment method for curling a lock of hair using a hair holder is provided. The hair holder includes a tubular body into which a lock of hair can be inserted from an opening at a first end of the tubular body toward an opening at a second end thereof, and the tubular body is configured to be capable of being rolled up. The hair treatment method includes inserting a lock of hair into the hair holder, rolling up the tubular body together with the lock of hair inserted in the tubular body so that a large diameter portion that has a tubular shape and forms an outer circumferential portion and a small diameter portion that is located inside the large diameter portion and has a space between the small diameter portion and the large diameter portion are formed, and performing curling while maintaining this wound state.

Abstract: Present invention relates to a process for permanent waving keratin fibers, especially human hair, for achieving durable waves wherein fibers are treated with a reducing composition, a non-reducing and non-oxidizing alkaline composition, a non-reducing and non-oxidizing acidic composition and finally an oxidizing composition wherein after processing the reducing composition the fibers are rinsed off.
