Good enough for a trim.
I've been to Marvel a handful of times, mostly because I'm a student and the price is more than fair. I find that they're a little hesitant to do any sort of style chnage (like add a fringe or do a drastic cut) but I always get a great deal when it comes to trimming off the dead nasty-ness that my shoulder legnth hair accumulates.
Overall, good salon, but remember that you're helping train someone- and not necessarily helping someone get their last couple hours in before becoming licensed. I've had a diaster or two, but in retrospect realize that expecting a waist legnth to pixie transition for less than $15 was just silly. Stick to trims.
