why sine? featuring jessi

April 2022

Jessi just celebrated her 10 year anniversary working with Sine. Her words mean the world to us. We can’t wait for another 10! Here’s what Jessi of West Town loves about Sine <3

“It’s hard to believe that ten years has already passed since my first day at Sine Qua Non. I remember walking by the Lincoln Park location when I moved here, thinking, “I really want to work at a place like that.” Getting this job has been one of the biggest accomplishment’s of my life. I’ve learned. I’ve grown. I’ve had opportunities I would never have dreamed of. I achieved personal goals I didn’t know I had. I owe this all to Laura Boton. She believes in me, uplifts me, and supports my dreams/failures, and encourages me to reach for more. I hope everyone gets the chance to work for someone as amazing as he once in their life. I’m so grateful!”

Our Reviews


COVID SAFETY is our number one priority.
As the Delta variant becomes the dominant strain in Chicago, we encourage the wearing of masks. However, our current policy is, if you have proof of vaccination you can have a maskless service if you prefer. We will continue to update our policy as things develop.

At Sine Qua Non, we know things happen. In order to ensure that we can accommodate all of our guests needs, we require that you give us at least 24 hours notice to cancel or reschedule your appointment.

We are unable to hold any appointment without a valid credit card on file. If you cancel without 24 hours notice or no show for your appointment, a charge equal to 50% of your service and will be charged to your card.

Our goal is complete happiness with your fresh cut and color. If you need an adjustment service, they are free within 2 weeks from your original appointment, preferably with your original stylist. If a refund is requested, our policy is: Call and schedule an assessment with management within 2 weeks of your service. You must come into the salon, so we can see the problem in person. If you received an adjustment at a different salon or cannot stop by so we can see your hair, we will not refund your services.

It is important to us that you are totally happy with your purchase. Product returns must happen within 30 days of purchase, be accompanied by a store receipt (and we can view in your client file) and the product must be nearly full. If you paid by credit card, you may receive a credit on your card. We are a completely cashless business.

We are committed to giving you the best one-on-one service available. If you are more than 15 minutes late, and we are unable to give you the attention you deserve, we ask that you reschedule your appointment for another day or with an available stylist.
