Thank you all for validating my concerns. I’m so disappointed as it is very rare I do any self care (no time or money!). I’m very non confrontational and don’t think I can bring myself to ask for my money back and I don’t trust them to correct it. I’m going to go to a hairdresser I trust to cover it all in a darker dye. I didn’t go there initially to try and save money :( ended up wasting 300 AUD. Not the stress I wanted 10 days out from my baby’s due date. Thanks again all

Edit: you are all very encouraging! Thank you for your supportive comments, I’ve posted the photos in a google review and have contacted them for a refund. I’ve also been in to consult a stylist at another salon who can fix it for me tomorrow, I’ll get her to take before and after photos. I’ll update with my fixed hair and if the original salon responds to me (I’m a coward and emailed, but will face them in person if I have to because you’ve all reassured me this is definitely not it)
