Problems solved by technology

[0006] However, these products usually contain relatively high concentrations of hydrogen peroxide, which in the long run can induce changes in the quality of the hair fiber, leading to a reduction in its cosmetic properties, such as its vitality, its shine and its mechanical properties, more specifically its mechanical strength the degradation of
[0007] Furthermore, the compositions employed often create odor problems, especially reducing compositions and especially those containing mercaptans
Hair treated with these compositions may also retain an unpleasant odor
