My girlfriend and I showed up for up-dos at 11:45am for a 6pm wedding. Ultimately, it was a waste of money for styles that fell apart that we could have done ourselves. Here is the rundown...
She had an hour and 15 minutes to do both of our hair, yet she RUSHED so fast and literally only spent 15 minutes on my hair. She finished both of us in 40 minutes - which tells you she was absolutely rushing when she had plenty of time.
I was specific about what I wanted and showed her photos - a formal low side bun, curled, with a small braid wrapped up in the bun in the front of my hair to give it more design. She did not do the braid (that would have added 2 minutes) despite my instructions, and when I asked for it after, she said it was too late, even though we had another 20 minutes before her next appointment. The bun looked like a birds nest and did not look classy at all.
My friends hair looked pretty, however both of our hair was a mess within a few hours (and we were sitting at a restaurant, not moving around) and we had to fix each others hair for the wedding. My bun was completely falling out within 5 minutes of casual dancing. Not a good experience!
