How much does it cost to strip hair colour in north east england (sunderland)?

I've had black hair for quite a while now even though i have only ever dyed it twice. My natural hair colour is medium brown/dark. Although I love my black hair, I'd preferr to have a brown hair colour due to summer coming up. I'm considering stripping my hair at a hairdressers, I know that it apparently recks your hair ect . and have heard about bleaching ect. How much would it cost in Sunderland/Newcastle, I can't find any pricing on the internet %26amp; not sure for the best hairdressers to ring up.

I payed for mine 80 pounds in London , i wouldnt recommend you to spend less on it because they go through a couple of stages to strip the color, its quite damaging for your hair so you really wanna go to someone that know what they doing.
