ABSTRACT:
The subject invention enables a more efficient management of hair by providing a novel preparation for waving, straightening, softening, or removing hair, employing as a key ingredient the compound thioredoxin or a thioredoxin-derived, or thioredoxin-like, dithiol peptide in combination with thioglycolic acid compounds. This invention allows hair to be treated at a lower pH to minimize hair damage when waving, straightening, or softening the hair; when used to remove hair, objectionable odors of commercial depilatories are minimized or eliminated.
