The present invention includes a hair relaxing composition for the straightening of hair. The composition includes a calcium hydroxide and guanidine carbonate. The present invention further includes a method for using the hair relaxing composition with the addition of heat to straighten hair.

The present invention provides a process by which smoothness, body and a permanent wave pattern can be imparted to multi-textured hair of all types, from hair having an excessively tightly curled appearance, such as Negroid hair, to hair having a straight appearance, such as Caucasian hair, with substantially less damage to the hair. The process of the present invention uniquely combines the use of two hair structure altering chemicals--an alkaline hydroxide (such as sodium hydroxide) and a thio...

A process for simultaneously cold waving and coloring hair in which the neutralization of the hair waving composition is accomplished in two stages, the second stage of which involves the use of a neutralizing composition containing a hair dye.

Methods of permanent shaping and volumizing hair that are gentle and prevent overcurling are described. In one method using curlers to curl the hair, an alkaline permanent shaping composition having a pH of 7.6 to 11 and including a hair keratin-reducing substance is applied to the hair and allowed to act on the hair for 5 to 30 minutes at room temperature or for 2 to 20 minutes at an elevated temperature. Then the hair is optionally rinsed with water and subsequently with an acidic aqueous inte...

This invention relates to a method of straightening, texturing and strengthening hair undergoing an alkaline straightening procedure and to nonacidic aqueous hair texturing and strengthening compositions for use in conjunction therewith. The texturing and strengthening compositions have a pH value from at least 8 to about 11 containing at least one water-dispersible hair texturing and strengthening agent including a quaternary nitrogen atom with at least one aliphatic alkyl group directly or ind...

In the process for permanent shaping of hair, the hair is first rolled onto rollers and a permanent shaping composition based on a keratin reducing substance is applied to the rolled hair. The permanent shaping composition is allowed to act on the hair for 5 to 30 minutes and then rinsed out of the hair with water. The rollers are unrolled and removed from the hair and the hair is styled. During the styling the hair is combed into a desired shape with a comb, a brush or with the fingers, and at ...

This invention relates to a method of straightening, texturing and strengthening hair undergoing an alkaline straightening procedure and to nonacidic aqueous hair texturing and strengthening compositions for use in conjunction therewith. The texturing and strengthening compositions have a pH value from at least 8 to about 11 containing at least one water-dispersible hair texturing and strengthening agent including a quarternary nitrogen atom with at least one aliphatic alkyl group directly or in...

A method of coloring selected hair shafts with a thixotropic hair treating material, while leaving adjacent hair shafts untreated, in which a thixotropic hair treating material is laid down onto a plurality of generally parallel spaced and non-overlapping areas running along the lay of the hair; and a method of touching up hair which has been so treated, after the roots have grown out.

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 viscosi...

The invention relates to a treatment process for obtaining a non-permanent reshaping of keratinous fibres, especially the setting of hair, comprising the steps of (i) contacting the fibres, which are maintained under mechanical tension and to which has been applied a composition containing at least one oil, with a gas containing water vapour, the gas having a temperature of at least 75.degree. C., for a time not exceeding 2 minutes to non-permanently reshape the fibres, (ii) cooling the fibres t...
