Process for semipermanent straightening and permanent shaping hair

A process for semi-permanent straightening and permanent shaping hair,

• wherein the semi-permanent straightening hair comprises the steps of:
• a. washing the hair with a cleansing composition and towel drying,
• b. applying a first treatment composition A on the hair, wherein the first treatment composition A comprises glyoxylic acid, at least one hydrate of the glyoxylic acid, and/or at least one salt of the glyoxylic acid or the at least one hydrate of the glyoxylic acid,
• c. leaving the first treatment composition A on the hair for 1 min to 90 min,
• d. optionally rinsing the first treatment composition A off the hair,
• e. drying the hair,
• f. heating the hair to a temperature in the range of 130° C. to 230° C.,
• g. washing the hair with a cleansing composition and towel drying,
• wherein the permanent shaping hair is carried out after the semi-permanent straightening hair such that the first treatment composition A is applied onto the hair before a second ready-to-use composition and a third aqueous composition C are applied onto the hair and the permanent shaping hair comprises the steps of:
• h. optionally washing and/or shampooing the hair and towel drying,
• i. putting hair under tension,
• j. applying to the hair the second ready-to-use composition obtained by mixing a composition B and a composition D,
• wherein the composition B is an aqueous composition comprising one or more reducing agents and one or more alkalizing agents, the one or more reducing agents present at a concentration in the range of 2 to 15% by weight calculated to a total weight of composition B, and having a pH in the range from 8 to 11, measured at 20° C.,
• wherein the composition D is a composition comprising:
• 1) ethylenediamine tetraacetic acid and/or its salts, and
• 2) malic acid and/or its salts,
• wherein the ethylenediamine tetraacetic acid and/or its salts (1) and the malic acid and/or its salts (2) are present at a total concentration of 10% to 100% by weight, calculated to a total of the composition D and the composition D comprises the ethylenediamine tetraacetic acid and/or its salts (1) and the malic acid and/or its salts (2) at a weight ratio (1)/(2) in the range of 2:1 to 1:100,
• wherein the second ready-to-use composition has a pH in the range of 6 to 12, measured at 20° C., and comprises the ethylenediamine tetraacetic acid and/or its salts (1) and the malic and/or its salts (2) at a total concentration in the range of 1.0% to 10.0% by weight, calculated to a total of the second ready-to-use composition,
• k. leaving the second ready-to-use composition on the hair for 1 min to 45 min,
• l. rinsing the second ready-to-use composition off the hair with water,
• m. optionally drying and heating the hair,
• n. applying the third aqueous composition C to the hair, wherein the third aqueous composition C comprises one or more oxidizing agents present at a total concentration of 1% to 20% by weight, calculated to a total weight of the third aqueous composition C, and having a pH in the range from 1.5 to 5, wherein the third aqueous composition C is left on the hair for a period from 1 min to 45 min,
• o. releasing the tension from hair in case the hair is put under tension in step (i), and
• p. rinsing hair and optionally washing with a cleansing composition.
