Researchers at L’Oréal patented a process to permanently reshape keratin fibers. The process comprises:

• applying onto the keratin fibers a composition comprising magnesium gluconate in an amount ranging from 0.01-5% by weight, relative to the total weight of the composition, wherein the composition has a pH ranging from 8.0-12.0;

• heating the keratin fibers after applying the composition onto the keratin fibers at a temperature ranging from 70-180°C; and

• rinsing the keratin fibers.

The process does not reduce or oxidize the keratin fibers, according to researchers.
