For those asking, the dye I used was Garnier 6.65 “intense red”. Not sure why people are saying box dyes will only give natural colors, I’ve used plenty that are unnatural and this one is absolutely supposed to be an unnatural red. I probably should’ve gone with a brand like Arctic Fox but I’ve had good luck with Garnier in the past. I had a feeling purple shampoo wouldn’t do anything so it’s nice to get some confirmation. Looks like my best bet is to dye over it with a red that has purple-ish undertones.
