If your shower water is poor quality, it’s likely because you live in a hard water area. Hard water contains high levels of minerals such as calcium and magnesium, which can leave behind residue on your skin and hair.
It may not sound like a big problem - after all, the water is safe to drink - but there are a number of hard water effects on skin and hair that you’ll want to avoid.
For example, the residue can build up on your skin, clogging your pores and causing or exacerbating breakouts. It can also coat the hair shaft, reducing shine, weakening your hair and making it more prone to damage.
Minerals can also strip away natural oils, leaving skin feeling dry, irritated, tight and generally uncomfortable.
You’ll find that shampoo, cleansing products and other haircare products simply don’t work anymore, and this is mainly because they can’t be rinsed out thoroughly due to the residue build-up.
These problems don’t generally appear after just one or two showers. It tends to build up gradually over time, so it can be difficult to figure out what the problem is. This is another reason that might struggle with how to know if you need a shower filter - you might be blaming another factor such as shampoo, stress, diet or even your hairdresser instead.
