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.

A process and composition for waving or straightening hair by treating the hair with an acidic reducing solution containing an amine sulfite, having a pH in the range of 5.0 to 6.95, followed by applying an alkaline oxidizing solution containing hydrogen peroxide, and having a pH in the range of 7.50 to 10.0 The process and composition solves certain problems which are commonly encountered in waving or straightening products, such as loss of hair color, and hair damage.

This invention provides compositions and methods for reducing odors associated with permanent hair waving by contacting the hair with a disulfide before, during, or after application of a sulfur-based reducing agent.

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...

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...

Curly or kinky human hair is permanently relaxed into a relatively smoothed or S-curved condition by a series of treatments involving application of a non-injurious composition containing a water solution of a salt of a weak acid to disrupt internal bonds of the hair, while manipulating and straightening the hair, then removing and replacing the first composition with a fixative to reconstruct or modify the structure of the hair, and finally applying a stabilizing composition which also acts to ...

A superior end wrap comprising a particular type of open-celled polyurethane foam of specified porosity and thickness which foam has been treated with certain types of weak carboxylic acids. Also disclosed is a permanent waving process using said acid treated end wraps.

A process for the waving or straightening of hair by treating with an alkaline bisulphite and or sulfite preparation followed by neutralizing with hydrogen peroxide is improved by using an aqueous neutralizing solution in which the hydrogen peroxide is present in a concentration of from 0.65 to 3.4% by weight and proportional to the concentration by weight of available sulfur dioxide in the waving/straightening solution used prior to neutralization. The process avoids certain disadvantages assoc...

Process for permanently waving or straightening human hair comprising the steps of pretreating the hair with a detergent solution containing an alkali metal- or ammonium sulfite, saturating the hair with an alkaline solution of a mercaptocarboxylic acid salt, winding the hair up on perforated hollow curlers or rollers having a diameter of 10-24 mm, rinsing the hair with water and removing the excess water from the hair, in separate steps or in a combined step treating the hair with peroxide and ...

In the process of permanently waving human hair with a thioglycolic acid or other mercaptan acid solution and rebonding the hair with an oxidizing rebonding agent, the present invention is the improvement comprising contacting the hair with a dye or tint after the reforming solution has been removed from the hair but before the oxidation rebonding is complete. In addition, the improvement preferably comprises admixing a tint or dye into all or a portion of the oxidizing rebonding agent to enable...
