I have been going to the same threader for the last two years over in Henderson. It has been so hit or miss lately with her so I decided to search for someone in my neck of the woods(southwest).
I went last week and as I pulled up on a 114 degree day their door was wide open. I walked inside and the woman there apologized but the AC had stopped working 20 minutes prior and the owner was out picking up a new portable unit. She said I could wait for her to come back or she could help me.
I let her help me and she did a really nice job on the shape but left so many really obvious hairs behind. I am assuming that she was flustered from the heat so I am going to go back because of the stellar reviews and see if the owner will do a more consistent job.
