Just a stone’s throw from London’s Baker Street station is Billi Currie, the contemporary salon named after its founder and renowned hairdresser. Inside, I’m greeted by the lovely stylist, Chris Donohue, who I can immediately tell is incredibly passionate and knowledgeable about hair. He begins by asking me which products I like to use and what I want to gain from the appointment. I explain that I like a voluminous look for my blonde, shoulder-length style, one that stops just short of a full, bouncy blow-dry. Chris tells me that he would like to add some texture to my locks as well as to improve their condition by replenishing the moisture.
