The brand design agency is also redesigning Michaeljohn's , as the salon prepares to expand its street presence by opening further salons across London later this year.
Ian Caulder, creative director at Caulder Moore, said: "Our aim is to make Michaeljohn the best kept secret in London for the discerning customer with a twenty-first century flagship salon where clients feel beautifully looked after.
"There's strong equity in the Michaeljohn brand -- through its history and association with the premium, glamour and first-class service -- and we'll be building on that to create a more unique and ownable design that will translate both into the salon and online to provide a blueprint for the future growth of the business."
Michaeljohn has styled hair for 40 years and counts Twiggy, Princess Michael and Princess Anne among its clientele.
