Hi Samantha
I can tell you my experiences of trials in a salon.
I done a set of nails for a salon to show what stage i am at doing nail extensions..which isnt perfect yet. She decided to take me on with some training, me offering to work for free ad i knew i needed experience, we advertised half price acylics for training purposes. When people came and had a set done she pressured me for time and i needed half an hour to finish buffing and shaping, i was rushed to finish and knew they wasnt finished, i need 2 1/2hrs for sculpted and gel polish, even her experienced nail tech took 2 hrs for just a gel removal and reapply, another client who admitted she was a picker said 2 gels had chipped off. Both coming back when i wasnt there to be redone. The salon owner then said after saying she couldnt see anything wrong with how i apply acrylic..i wasnt ready to work in a salon..i questioned this as we agreed training but she laughed and denied she any training was being offered and had no time to train..even though advertising was done for nail tech to train. This really made me angry and knocked my confidence as i wasnt given a fair go. I need extra time as it is having a disability and this sucked!
I hope you find an honest salon , make it clear you want training and get it in writing if you can.
