At one point in my life I became obsessed with O.P.I nail polishes and hair extensions. Trade secrets was my go-to-store to get these items. They have a large selection of O.P.I polishes right at the entrance of the store, and they are often buy one get one free! SCORE! Last I checked a bottle was just under $ 10.00. The hair extensions are just beside the O.P.I rack! Double SCORE! Customer service is fantastic, and the girls working at this location are bubbly and happy to help, if needed. The staff do get commission, but I have never felt pressured into buying anything. They carry unique products as well as a lot of hair equipment; blow dryers, straighteners, curling irons. The prices are comparable to what you would find in salons; $ 30.00 bottles of shampoo, $ 40.00 hair masks. They also have a hair salon on site.
