Oh, give me a break. My hair gets dyed professionally every 4-5 weeks, and I do everything in my power to keep my red at optimum color, from washing every few days, to using color-safe shampoo/conditioner, and only washing with cold water. And making sure I use clarifying shampoo to get all the junk out right before I get it dyed. Even my stylist comments that I keep up my red quite well. And while I do get a lot of questions on how I maintain my color (like you), I also get rude comments as well. You’re just lucky, but no need to be an asshole like them about it.
