The present invention provides a method which achieves a simultaneous coulouring and straightening of the hair in a single step, utilizing a hair treatment composition comprising at least one carboxylic acid of formula (I) defined below and at least one direct dye:R&#x2014;CO&#x2014;COOH&#x2003;&#x2003;Formula (I) In another aspect, the invention is directed to the hair treatment composition and the use thereof for straightening and colouring the hair.

Process for one-step colouring and straightening hair

The present invention a process for straightening the hair, using a composition comprising at least one carboxylic acid of the formula (I): R&#x2014;CO&#x2014;COOH Formula (I) The process of the invention is characterized in that it involves the treating of the hair with the composition and the drying of the treated hair under conditions of mechanical tension and hot air flow having a temperature of 60-140&#xb0; C.

Hair treatment process

The present invention relates to a process for reducing the frizziness and improving the manageability of the hair, wherein the hair is treated with a cleansing composition and/or a conditioning composition comprising at least one carboxylic acid of the formula (I): R&#x2014;CO&#x2014;COOH and/or a hydrate thereof and/or a salt thereof.

Process for treating hair

The present invention provides a hair straightening composition with improved ease of use, which leads to an enhanced smoothness of the straightened hair. The composition comprises at least one carboxylic acid of the formula (I) in combination with at least one quaternary ammonium compound having two long-chain hydrocarbon groups: R&#x2014;CO&#x2014;COOH Formula (I). In further aspects, the present invention concerns a process for semi-permanent straightening of the hair, utilizing said composition, the use of the composition for straightening hair, and a kit comprising the composition and a straightening iron.

Composition and process for semi-permanent straightening of hair

The present invention relates to a process for semi-permanent hair straightening and aftercare treatment and to a kit of compositions for use in this process. In the process of the present invention, the hair is firstly subjected to a straightening treatment using a straightening composition comprising at least one carboxylic acid of the formula (I): R&#x2014;CO&#x2014;COOH defined below and/or a hydrate thereof and/or a salt thereof. Then, a specific cleansing composition and/or a specific conditioning composition comprising at least one carboxylic acid of the formula (I): R&#x2014;CO&#x2014;COOH defined below and/or a hydrate thereof and/or a salt thereof are used as aftercare products in order to improve durability of the straightening effect.

Process for semi-permanent hair straightening and aftercare of the hair

The present invention provides a hair straightening composition with improved ease of use and reduced smoke development during the application of a straightening iron. The composition comprises at least one carboxylic acid of the formula (I) in combination with at least one polymeric thickening agent selected from non-ionic, anionic, cationic and amphoteric polymers having a viscosity of at least 500 mPa-s measured at a polymer concentration of 1% by weight, in water and at 20&#xb0; C. with a Brookfield viscometer: R&#x2014;CO&#x2014;COOH Formula (I) In further aspects, the present invention concerns a process for semi-permanent straightening of the hair, utilizing said composition, the use of the composition for straightening hair, and a kit comprising the composition and a straightening iron.

Composition and process for semi-permanent straightening of the hair

A composition for the permanent shaping of human hair, with good waving capability while avoiding damage to the hair, comprises at least one reducing agent and 0.1% to 15% by weight, calculated to the total composition, of 2-methyl-1.3-propanediol.

Composition for the permanent shaping of human hair

Composition for permanent waving of human hair comprising an at least partly water-soluble chlorophyll or chlorophyll derivative, especially an alkali magnesium or copper chlorophyllin to improve the waving performance of the composition.

This invention refers to a composition for permanent waving of human hair, containing thioglycolic acid or the salts thereof, preferably the ammonium salt, and comprising two compositions which are kept separate until application, whereof a Composition (A) contains at least an amino acid hydrochloride and at least one polyol or the methyl and ethyl ethers thereof, preferably 1,2-propanediol in aqueous solution, having a pH-value of preferably between about 4.5 and 6.5, and a Composition (B) which is kept separate from said Composition (A) until use contains ammonium carbonate, ammonium hydrogen carbonate, and (or) ammonium carbamate as alkalizing agent(s), having a pH-value between about 8 and 9.5, and both compositions are mixed before application whereby a pH-value between about 7 and 8 is obtained. The compositions, which are kept separate, present outstanding stability; upon application after admixture optimal waving performance and, at the same time, gentle treatment of the hair is achieved.

Composition for permanent waving of human hair

A permanent waving composition showing excellent waving properties and, at the same time, a hair conditioning effect contains

A permanent waving composition for human hair without any skin sensitizing effect comprises as reducing agent 1,3-propanediol monothioglycollate and 1,3-propanediol dithioglycollate alone or in admixture with other reducing agents, wherein the content of 1,3-propanediol dithioglycollate is not more than 10%, preferably less than 5% by wt., calculated to the monoester.

The invention is related to a composition for the permanent waving of human hair with improved properties of use, containing alkanediols in combination with ammonium carbamate as alkalinizing compound.

Composition for permanent waving of human hair and use of ammonium

A mild permanent waving process for human hair including the steps of applying a reducing composition containing at least one thio compound, subsequently pre-fixing with a composition containing at least one dithio compound without previous rinsing, and finally fixing with a composition containing an oxidant, especially hydrogen peroxide, in a low concentration.

Process for permanent waving of human hair

Agent for the long-lasting shaping of hair, on the basis of a thioglycolic acid ester as reducing agent, preferably of a glycerol monothioglycolic acid ester. The permanent shaping agent contains, in addition to the thioglycolic acid ester, an amount of 2-mercaptopropionic acid monoglycerol ester and/or 3-mercaptopropionic acid monoglycerol ester as shaping agent, and at least one solubilizer.

Agent for the long-lasting shaping of hair

The permanent shaping agent containing one or more hair keratin-reducing active substances is adjusted by means of stiffening additives to a consistency that is viscous to cream-like at room temperature with a viscosity of over 100 mPa.times.s. The stiffening additives are selected such that the permanent shaping agent, upon warming to a temperature with a temperature range between 25.degree. and 42.degree. C., undergoes a decided loss of viscosity of over 60% with respect to the initial viscosity, to a value under 50 mPa.times.s, i.e., becomes fluid within this temperature range. The permanent shaping agent of raised viscous or creamy consistency is applied to curled hair on curlers and then the viscosity of the permanent shaping agent is lowered, by elevating its temperature in situ, so that the liquified agent penetrates into the hair on the curlers.
