what popular beauty routine do you wish people would STOP talking about?

I've been looking into doing at-home brow tinting and everywhere I look, people recommend using men's beard die. I can't stand it, because those products are NOT safe to be used that close to eyes (they usually contain ingredients like hydrogen peroxide, which is approved to use on a beard but not on brows/lashes because it's so much closer to the eyes). I swear it's the only product people will recommend and it got me thinking: what else out there do you wish people would stop recommending?
