Time Out says
Picture-perfect balayage, Instagram-worthy waves, and barnets every shade of the rainbow; That’s what you can expect from Foster London, a cutsie, laid-back salon that’s just a stone’s throw from Shoreditch Overground (they’ve got another over in Dalston, too). Run by siblings Drew and Nadia Foster, the salon strikes the perfect balance between trendy and twee. Inside it’s all pastels, bleached wood, retro artwork and cat ornaments. Sadly no actual felines, but I’m told there’s often a friendly pooch or two to greet you in reception. There are bright cutting stations and a mosaic basin area downstairs, while on ground level the salon looks out over Boxpark. It’s a sun trap, ideal for a spot of people watching, just as long as you don’t mind passersby peering back at you with your foils in.
Foster London doesn’t just look good though, the team are creative, knowledgeable and attentive. They don’t rush (even when you’re running over your appointment time late on a Friday night) and they constantly check to make sure you’re happy with your hair’s progress. You can trust them to take you to some really wacky places, but if you’re after subtle, you’re not going to walk out the door with a do you’re uncomfortable with either. I was a hair-dye virgin when I first stepped foot inside Fosters and after some gentle guidance from one of the colour experts was persuaded to go for something different. The end result was a bouncy, biscuity balayage that suited my skin tone and face shape much better than what I’d originally asked for. Hair heaven.
