The hairdresser that did my haircut was unskilled.
I've asked the lady to give me the same haircut but a shorter version (long layers).
Instead I got scalped and ended up with really uneven layers that could be seen with the naked eye, it was a visible discrepancy that was hard to fix. Another haidresser I went to after had to take off quite a bit of hair to fix her mistake. I didn't want to make a scene because she was very nice to me but unfortunately she has no idea how to cut hair.
