Moving cities or countries can create all kinds of challenges and changes, from where to get the food that you like to finding a doctor that you can trust. Things like water don’t typically land on your radar as a lot of cities or countries you take for granted you can turn on the tap and drink what comes out.
Tap water in northern India has been known to have high levels of Nitrate, fluoride and even Arsenic which is alarming. Now obviously using RO water to shower is most likely unrealistic for most, rinsing your hair after you shower in it is achievable. A little fuss but it may well be worth it when it comes to protecting your hair! It can cause hairfall, dehydration & color fade
Now whilst simply rinsing your hair in filtered water is not going to be as good as showering in glacier water but it most certainly is putting your best efforts into a healthy growth. Also good to remember brushing your teeth and cleansing your face use RO water also.
So the answer is yes, rinse with filtered water 💦
