Highly recommend Jolanta!
I recently purchased a Groupon for a Brazilian wax with Skin Updgrades/Jolanta. She is very friendly and fast with the waxing. There was no awkward silence like some salons I've been to when getting waxes. Her pricing is very reasonable for Scottsdale so I will come back.
Her studio is located inside Salons by JC, which has multiple beauty studios in there. It's behind Red Lobster & near a bicycle shop.
