update from your friendly neighborhood hair family

March 2020

Sine Qua Non is proactive 😎 Due to the rapidly changing Covid-19 situation, we’ve decided to move our opening date to April 14th for now, though that will likely get pushed back by the City of Chicago.

Get booked for your next service by emailing sine2@sinequanonsalons.com. We will be super busy by the time we can get back to work, so please book ahead! We love you!

We are so grateful to our loyal customers 🙏🏼

Need products during the shutdown? You can now purchase products on R+Co and Oribe’s websites and help Sine in the process. Our product partners will share the sales with their networks!! Awesome!!

Please use this R+Co link.

For Oribe products, please enter SineQuaNon in the “add code” box at checkout on http://Oribe.com

We can’t wait to do your hair, Chicago!


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.
