Keratin Treatment and formaldehyde, what is the all the debate about?
• BKT has been available in the UK for the past few years, famously used by Girls Aloud; it has been in the US for much longer. The primary chemical in BKT is Keratin – which holds the hair. However, most BKT treatments also have formaldehyde in it. • Formaldehyde is not a nice chemical, and has been linked to cancer. There are no known cases of death or even illness from its use in BKT, and the concentrations are so low, and the exposure so minimal it is unlikely to have an effect for the customer. The stylist, on the other hand, has regular exposure to the chemical, on a daily basis and for this reason some hair dressers simply will not work with it.
