The peroxide blonde hair color worn by Marilyn Monroe cannot be achieved with hydrogen peroxide alone. The addition of ammonium persulphate, which is usually supplied as a powder, is required to completely decolorize melanin and achieve the platinum blonde effect. This process causes damage of a much higher magnitude than conventional permanent colors and hence the degree of haircare must be suitably increased.
Permanent colors and high-lift bleaches are biologically aggressive treatments that are well-tolerated by the hair when utilized properly. Problems such as hair breakage and strawlike appearance can result from a lack of understanding of how the hair is changed by these processes. A patient with shoulder-length hair will require treatments once every six to eight weeks. As a result, the ends of the fibers will have experienced significantly more chemical and physical insult compared to the roots.
