The old adage that eyebrows are sisters, not twins, is not one that celebrity brow artist Hollie Parkes adheres to. In fact, after stepping out of her studio at Claridge's following her £400 Brow Spa treatment, my eyebrows have never looked more identical; there wasn't a single hair out of place.
But what exactly is a "Brow Spa"? Parkes tells me she wanted to completely reframe the brow styling experience and create something that felt both results-driven and deeply relaxing. Indeed, her dimly lit room at Claridge's is a world away from my usual threading setup at the local nail salon. Here, an entire hour and a half is devoted solely to the hair above my eyes.
