Hair help! Please!

So I got my hair done for the first time, a week ago. I'm not sure how to say it but I got a baylage(?) I went from black hair to bleached blondish hair. So some hair has been turning more blonde and others orange! I've been using purple shampoo but idk. What can I do and how long should I wait before getting it done again? I just want to go full brown. This is too much. Its been 8 days.
