I've been going to the same hairdresser salon for years, very nice, friendly staff.
I have the same colour every time, whatever it is is described in my notes they just look it up on the system.
Today instead of a coppery brown I've come hope with almost jet black hair. It's very close to my natural colour and I now look very like my estranged mother so I absolutely despise it
They've asked me to come back in later to have a look at it. I asked if it's likely to be fixable but they couldn't say over the phone.
They were lovely and I'm not cross or anything but a bit peeved that I've had to sit in a mask for 90 minutes only for it to need to be repeated.
I've no experience of these things so not sure I should be paying full price? It was 91 quid and it's not what I asked for at all.
