Namely
Thioglycolic acid modifies the hair fibers to facilitate their restructuring: it is used, for example, in hair restructuring products. It is also used to chemically decompose unwanted hair so that it can then be removed by simply wiping it off. It is its potassium salt which is the most used today.
