R+Co Products

At Sine Qua Non we love embracing change and we are thrilled to announce our new partnership with a luxury hair product line: R+Co. Unlike any other hair care line, R+Co is a “first-of-its-kind salon brand.” Not one, but three of the industry’s leading hairdressers collaborated to create this “superbrand.” Howard McLaren, Thom Priano and Garren have created paraben-free, sulfate (SLS or SLES)-free, gluten-free, vegetarian, cruelty-free and color safe products that are designed to inspire hair artistry and creativity.

Along with these incredible products, an inimitable education program is underway and Sine Qua Non stylists are eager to partake!

“Embracing the Culture of Hairdressing means embracing the unique education required to inspire the diverse needs of the hairdressers of today. R+Co will also bring new educational tools and approaches to stylists.”

We want to send out a special thank you to Howard McLaren for helping make R+Co a reality in our salon. His guidance and support is immensely appreciated by our staff and owner, Laura Boton.

These products speak for themselves; the quality, innovation, and execution of the brand are undeniably superb.

Come into any Sine Qua Non location to purchase or to learn more.

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.
