I hate this. I understand doing it in the 30-odd minutes it takes for the colour to set, but leaving me there while they see multiple clients really pisses me off.
I had an argument with the last hairdresser I went to and refused to pay for my dye job. I came in, they started me 30 mins after my appointment time, with the junior obviously. The head stylist came over and muttered with the junior behind my back and looked at a swatch board – bear in mind I was only getting my roots done. Left and went back to someone I imagine was her friend, they were speaking in a different language and laughing away – although as far as I could tell this woman was getting nothing but a trim?
They left my hair colour on for 1.5 hours, and when it was eventually washed out (by the junior again) she said she would blow dry it. After blow dry, I had been there over 3 hours and the colour of my roots was dramatically different to the rest of my hair.
I pointed this out, the head stylist vanished leaving me to argue with the junior who kept running back into the other room to get instructions, and returning to relay them to me.
After 3.5 hours, I had a very poor frizzy blow dry and dead black roots. For this privilege they wanted to charge me £80 (head stylist rates, obviously, and the blow dry itself was £34!)
