My nan got her hair stripped and dyed hot pink for about £55 it was a really good job but I guess it kind of depends on what colour you're looking for and, like, how many colours you want in it,,,,, I'd say the extream colours cost a bit more : )
How Much Is It To Get Your Hair Stripped At A Hairdressers?
It takes maybe 2 hours
My step brother got his hair stripped and coloured in red and purple and that cost £60 and he had a fair amount of colour put in :)) so I'd go and ask my hairdresser because they might be able to give you a better estimate :))
