Mineral deposits can accumulate, making hair drier, but removing them can cause different problems
From hair treatments to shower filters, a wave of products have been launched promising to protect hair from the “problems” caused by living in a hard-water area. But are they really necessary? “Hard water has a higher concentration of dissolved minerals, especially calcium and magnesium,” says Desmond Tobin, professor of dermatological science at University College Dublin. “These are naturally occurring in water, particularly water that is not rainwater.”
When water moves through soil and rocks, such as limestone, minerals dissolve into it and remain there when it comes out of your tap. These minerals are responsible for the limescale that builds up in your kettle.
