To ask for a refund if I don't feel confident in the hairdresser?

I had a full head of highlights beginning of the month - thought it looked incredible from the angles I was shown and how it looked when it was down.

Except this is far from what it looks like underneath. Lots of the highlights have "bled", meaning rather than fine strands of colour, I have uneven blocks/stripes. Also all of my natural colour that wasn't highlighted has been left ginger due to the toner. From independent advice I've sought, I'd need all of the non-highlighted hair colour matching back to my natural, as well as lots of very fine foils through the blocks of colour to break them up. It's allegedly a ~6 hour job, whereas the rectification appointment I have booked is just 2.

I understand I should give the original hairdresser opportunity to fix it before asking for a refund, but my hair was left in an already damaged state following the last appointment due to having highlights aplied over previous highlights. I'm genuinely concerned this upcoming appointment isn't going to be adequate time to undertake such a large amount of recolouring, and I'm also worried for the integrity of my hair.

At what point am I BU/NBU to say to the hairdresser that I don't want them to rectify it and would like some form of refund?

No idea regarding refund, I’ve never had to do that with a hairdresser before - I’m assuming you don’t ask, you don’t get. But I’d be fucked if I’d be going back to the same person who made such a hash of it in the first place.

They'd obviously have known they cocked it up underneath whilst they were drying it. Not unreasonable to say you want a refund to get it corrected elsewhere.

Thank you both, these are both my trains of thought. Either they realised and said nothing, or didn't realise there was anything wrong which is possibly even worse given how obvious it is even to someone untrained.
