Lately my skin’s been acting up and my hair feels like straw, no matter what products I throw at it. A friend swears it’s my hard water and keeps telling me to get one of those filtered shower heads, but I’m not trying to waste money if it’s all hype. I’ve gone down a YouTube rabbit hole and now I’m even more confused. Did a filter actually make a difference for anyone here? Smoother skin? Less frizz? I’m desperate for a win at this point and would love any real‑world experiences before I hit “buy.”
