The Link Between Hard Water & Damage (And how to fix it!)
Posted by Petals Hair & Beauty on 11th Apr 2026
Approximately 85% of Irish homes are impacted by hard water due to high levels of calcium and magnesium, which damages hair by creating a buildup that ultimately leads to dryness, breakage and dullness. More than that, the mineral buildup can also lead to rapid colour fading, as well developing brassy, orange and even green undertones to your hair.
Many of us think that purchasing a good shower head with built-in filters will soften the hard water, but they are only effective in removing chlorine and heavy metals and so the damaging calcium and magnesium stay behind. That's where the Kérastase Première range comes to the rescue, using high concentrations of citric acid and glycine to removes calcium buildup, while reconnecting broken keratin links to restore up to 99% of hair's original strength. The damage done to your hair can be reversed, with hair looking brighter and feeling softer after only the first use.
Know the range:
Pre-Shampoo Treatment: The hero product, used on wet hair before shampooing to maximize effectiveness, acting on inner & outer hair layers to neutralise dullness and stiffness. The formula rebuilds broken keratin bonds to reduce breakage.
Shampoo: Cleanses and delivers advanced repair to all levels of damage for all hair types
Conditioner/ Masque: Deeply restores and intensily repairs all types of damaged hair, protecting against further breakage.
Serum: Helps seals the cuticles of damaged hair, while filling over external damage to the fibre and reinforcing hair strength. It's like a super shield, working to protect your hair from the calcium overdose found in hard water plus from humidity, and heat up to 230°C.
*Kérastase Première Hair Routine also allows for up to 72 hours frizz free*
