February 2013

Longtime Sine Qua Non client, Carisa Barreca, shares some tips on maintaining her beautiful blond hair from her stylist, Sonia Vella.

You have gorgeous blond locks! Where do you go to maintain your tresses?
“I go to Sonia Vella at Sine Qua Non Salon. She is amazing. I even hesitate to give out her name because I don’t want everyone knowing about the absolute best stylist in Chicago. You would be absolutely mad not to go to her…wait…never mind…don’t…I’m selfish.”

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.
