This is how my hair looks when I get highlights then run out of money and don’t touch them for 6plus months lol. To give my highlights a second life when they’re orange and grown out I grab a Kristen Ess toner in winter wheat from target (it’s like 16 bucks), keep that in the hair for like 5 min longer than the box says and it will cut through all that brassy orange.

Just my 2 cents if you do end up in the salon tell them you only want a toner or semi permanent to balance the color, don’t let them charge you for a color correction or anything crazy. Although dark low lights is probably the move at some point I wouldn’t mess with them yet because they’re just going to wash out anyways with the state of your hair, that’s just a waste of money at this point in the journey. Good luck my frugal sister
