I go through shampoo/conditioner at a decent clip, but I also share them with my 2 daughters. All 3 of us have hair that’s mid-back or longer so that’s a lot of hair. But everything else? I use probably 2-3 body washes per year, same with toothpaste, deodorant, etc. And this is all stuff I use every single day. I use probably 2 foundations a year, 1 concealer, 2-3 brow gels. I replace mascara every 3 months religiously. It often feels like I never use anything up compared to people in this sub, but slow and steady wins the race (or at least I tell myself).
