women’s history month- spotlight on the wonderful women who run sine

March 2024

Happy Women’s History Month! As a woman owned business that just celebrated its 30-year anniversary, we wanted to take the time to give a shout out to the amazing, organized, passionate women who help our business thrive. First up, we wanted to share a bit about our owner: Laura Boton, who inspires us daily with her leadership.

Thirty years ago, Laura embarked on her business owner journey, opening up the first Sine Qua Non in Lincoln Park. She was featured in the Chicago Reader as one of Chicago’s “Top Young Stylists” and she’s done so much since then, cementing her as a powerhouse in hair, styling, and business. Laura’s goal was to create laid back and non-judgmental salon environments that would foster diverse and impeccable hair talent.  Her goal came into fruition with her the 3 salons you know and love today, each containing their own vibrant energy.

Before spotlighting our fantastic salon managers, we wanted to share some exciting news! As business has continued to grow, we’ve recently welcomed back our beloved Regan Alanes to the team after her 5+ year leave. She will be helping Laura and the other managers with coaching, personnel, and more.

Our lovely Hillary who manages West Town will be celebrating her 13 year anniversary this year. When asked what she loves about Sine, she shared, “I love working at Sine because of the wonderful people who work here! Our little West Town community really lifts each other up and it’s a joy to experience.”

Our hardworking Lakeview manager, Vanessa, will be celebrating her 9 year anniversary with us this year! When asked what she loves about Sine, she said, “I love working at Sine because of the warm welcoming environment and getting to see stylists use their creativity to produce gorgeous looks!”

And last but certainly not least, our talented Andersonville manager, Jen, will celebrate her 5 year anniversary with us this year. When asked what she loves about Sine, she shared, “Laura B is a genuine advocate for her employees. I always feel supported and heard by her and other managers, and that makes the Sine team so much stronger!”

As you can see, our managers have stuck by our side for a long time and even those who pursue other paths sometimes come back to us – shoutout to Regan! 🙂  We can attribute our managers’ love for their work to our stylists, assistants, and clients who make Sine a kind, safe, and fun place to be!

Our Reviews


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.
