Sine Qua Non Salons began in 1993 when Chicago hair stylist Laura Boton created the go-to hair destination for Chicago’s creative community. Sine’s award-winning salons in Chicago deliver exceptional artistic haircut and hair color services in a warm and inviting atmosphere. Considering Laura’s background as a musician, it’s not surprising that SQN quickly rose to fame on the local arts scene, attracting Chicago’s artistic community to call Sine their hair home. Our team of innovative hair stylists create flattering, on trend, easy to wear looks that fit each individual perfectly.
Consistently awarded Best Hair Salon in Chicago – our three locations are the place to experience superb, on-trend service. Welcome to Sine Qua Non Salons.
