I've been to Rod Sickler twice and my experiences were very different. I get waxing done when I go there and the first time I went my hair grew back very quickly after I got waxed. I was angry at first, but after a couple months of going elsewhere I decided to give it another try.
My second experience was much better. The hair did not grow back for awhile after the wax. I am not sure if they used different types of wax on me, but mixed experiences here!
