Hair color 🗣🗣

Alyssa

So I’ve been getting my hair highlighted for about a year and I’m currently VERY blonde but I wanna switch it up and go back to a cool brown for a little bit. I only want it to be temporary though. What’s the best way to do this? Toner ? Demi permanent ? ( I can’t go to my hairstylist for a couple months because I’m away for school right now but if I like the brown I’ll have her do it but with a more permanent color)
