KHS is the brainchild of a skilled team of industry professionals. It all began with a hair salon in Muswell Hill, London, where stylists were regularly asked to perform Brazilian Blow-dry treatments. Despite its popularity, some customers had reservations about the ingredients, including formaldehyde, and the labour-intensive nature of the process. This customer feedback gave rise to KHS, a keratin straightening system that could be used without worrying about chemicals or complexity - just three easy steps.
