Unfortunately for most of us, hard water is what comes out of our shower heads.
And that is your hair’s worst nightmare.
Water starts as ‘soft’, but when it flows through soil rich in minerals, it becomes ‘hard’.
Hard water contains higher amounts of calcium and magnesium. The more of these minerals, the harder your water.
These minerals causes frizz, drying and roughness. Other than relocating for purer water, here are five ways to improve your hair health when washing with hard water.
How does hard water affect your hair?
Hard water can affect the texture of your hair and how it behaves, according to president and consultant trichologist at Philip Kingsley, Anabel Kingsley.
“Many people notice their hair is drier when they shampoo with hard water, that it frizzes more easily and that not as much lather is created.
“To help hair health, I recommend our iconic Elasticizer Deep Conditioning Treatment, putting elasticity back into the strands of the hair, and therefore re-hydrating and re-moisturising hair that may have become dry due to the build up of minerals in the hard water.”
Cloud Nine’s group education manager, Marie Nieuwoudt, says the effects of hard water on colour are even more severe.
“[Hard water] can cause brittleness that leads to breakage, a dull appearance and for coloured hair, fading – though it can even fade your natural colour in some cases.”

Hard water and heat-damaged hair
If your hair is heat-damaged, the effects of hard water are even more visible.
“Thin hair can appear even limper and lifeless due to the weight of mineral deposits in hard water,” says Absolute Collagen’s clinical trichologist, Eva Proudman.
“For those with heat-damaged hair, the compromised cuticle becomes even more susceptible to the harsh effects of hard water, exacerbating existing damage.”
Due to the high mineral content, hard water can leave deposits of its minerals in the hair, blocking much-needed natural oils and moisture from hair products.
“This impacts all hair types, but can have a much bigger effect on bleached, thick and heat-damaged hair that needs a little extra TLC,” says Nieuwoudt.
“Also, if there’s too much copper in the water, this can leave a green hue in bleached and naturally light, blonde, fine hair.”

How to reduce the effects of hard water
Fortunately, not all hope is lost if you’ve been exposing your hair to hard water for a prolonged period of time.
Beyond products, Kingsley recommends incorporating a water filter into your shower, whilst Proudman suggests using a diluted apple cider vinegar rinse or jojoba oil to further eliminate deposits and restore shine.
When it comes to your haircare routine, Nieuwoudt recommends the Colour Wow Dream Filter, “it’s a pre-shampoo mineral-remover for a hard-water detox, and the Metal Detox range from L’Oréal offers an anti-metal routine for all hair types.
“There’s also a great website called Aqua Cure Water Purity Experts which can help you to see if you live in a hard water area prior to starting a new haircare routine.”
