This often leads to more usage and this coupled with hard water can make the skin dry and hair frizzy and brittle. It is therefore essential to curb its damage. Here are a few tips which will come in handy when dealing with hard water. Firstly add a spoonful of alum to your bucket of water as this will help the minerals settle at the bottom of the bucket.
