Customer service was hard to find walking around the store, but once I found one, it was easy to find what I was looking for. Defintely have in mind what you're looking for and price-point, otherwise you may be taken on a wild goose chase.
I definitely recommend getting your brows shaped at the Brow Bar [make an appt], it's not something available at my "local" Ulta and Acacia is a wonderful "brow stylist"! She has done my aunt for a few years now, and any time my mom visits Phoenix (from Indy) she goes there - you know it's worth the visit if that happens. :) I hope to visit again this year and get them done!
