The hairdresser was okay, but she didn't pay much attention to what she was doing. She was often talking to other people, which probably contributed to several mistakes, including when thinning my hair.
As a result, my haircut (a classic bob) was shorter on one side. I only noticed this when I got home and looked closely in the mirror. I went back the next day, and they corrected it, but in the end my haircut was shorter than I wanted.
They also charged me £50 instead £40 that I had booked for.
