I have medium brown hair.
I would like this to be ash blonde and olaplexed during dying to try and avoid breakage.
I am in wales and outside major cities.
How much should I expect to pay for the initial 'dye job' and then how much/how often for maintenance??
I'm clueless, have never really spent money on my hair so don't know what I need to be budgeting for.
Thank you
