I have been to Balayage for eyebrow threading a couple of times now and Sou is always super efficient and quick. Plus she gives amazing advice about how to style your eyebrows after threading and knows what looks good to enhance your face. I like a natural shape as I have pretty strong brows but she tidied them up without over-threading (which I'm sometimes worried about) I highly recommend Sou for eyebrow threading, and she is lovely!
