A composition and a method for treating hair are disclosed. The composition improves properties such as the hand (feel), curl retention, color receptivity, color retention, shine, and strength of the hair and the compositions can be used to prevent or repair damage to hair caused by hair treating processes (e. g. , hair waving and coloring). The composition is useful in a rinse-free waving process, that is, a permanent waving process in which the intermediate rinse between the reducing step (the waving step) and the oxidizing step (the neutralization step) is omitted. The composition is also useful in a coloring process and in a one-day combined rinse-free waving and coloring process. The composition contains (1) an alkaline earth metal (e. g. , magnesium or calcium), zinc, or aluminum, preferably in the form of a water-soluble salt (e. g.

This invention relates to improved hair waving and straightening compositions of matter. The novel compositions of matter of this invention comprise a sulfite and/or bisulfite reducing system, urea, a cationic polyquaternary resin of such a nature that in combination with the urea in the reducing system a hair waving and/or straightening effect equivalent to conventional thioglycolate systems is effectuated without the attendant unpleasant odors associated with the thioglycolate systems. In addition, the reducing system of this invention is less damaging to the hair and skin than the thioglycolate systems. The system of course may be used either with or without heat such as heat from hair dryers. In order to achieve the above-mentioned objective, the compositions of this invention are at a pH in the range of above 5. 5 to about 8.
