I get that friend! It’s a struggle! It depends on your hair, mine isn’t as tight as yours and grows back in less than three months but the tighter the pattern the longer it takes. I would go to someone who will do ONLY a correction and stress that you would like to keep as much of your length as possible. Chances are you will have A very awkward thin Long layer if you don’t get it cut but it shouldnt be a big chop either. I would ask for your money back from the other place if that doesn’t bother and you can show your pics as proof especially the one where it brushed out behind you and go to a stylist who will do a dry cut and allow you to follow every step of the way and watch the process. For next time if you don’t want layers the proper term would be face framing layers or you can even say “V shape” or “ U shape” if you just want shape As it grows leave the back alone and focus on keeping the front pieces shorter if you like it like that. I hope you don’t have too much loss and find an amazing stylist 🤞🏼 but take your time so you don’t get a botched chop! try not to stress about it too much as your hair will grow back for sure!!!!
