摘要：
A hair fiber strengthening composition includes an aqueous vehicle containing as a hair strengthening additive a source of metal cations having a valence of 2 or 3 and anions derived from an oxidized carbohydrate, an inorganic acid and/or an organic acid, the composition having a pH of less than about 6. These compositions have the advantage of strengthening the hair fibers without the undesirable effect of darkening or spotting the hair, particularly light-colored or bleached hair. These compositions are particularly useful for strengthening hair that has been subjected to potentially damaging chemical treatments such as bleaching, coloring, or relaxing, or to provide a strengthening effect prior to and in anticipation of such chemical treatments.
