Calcium plays a vital role in our bodies, but when it comes to hair, it’s possible to have too much of a good thing. The presence of calcium in water can have a negative impact on hair health. Fortunately, Kérastase has introduced the Première collection, expertly developed to address the often-overlooked issue of calcium buildup in hair.

The Impact of Calcium on Hair

While some locations are more prone to calcium due to water filtration, almost all water has at least a trace of it. Here are four ways calcium can harm your hair:

Stiffness

Calcium interacts with the proteins in hair fibres, leading to increased stiffness. This effect can make your hair feel rough and unmanageable, resulting in more breakage during styling or brushing.

Dullness

Calcium can create a film over your hair, diminishing its shine and vibrancy. This buildup can also inhibit moisture absorption in the hair shaft, leaving it dry and lifeless.

Weakened Structure

Calcium compromises the protein structure of your hair, making it more susceptible to breakage. This is particularly concerning for those with already damaged or porous hair, as it amplifies the issue.

Acceleration of Existing Damage

Damaged hair absorbs calcium at three times the rate of healthy strands. Consequently, this increased exposure can worsen existing damage because the porous nature of compromised hair makes it more vulnerable to calcium absorption, creating a vicious cycle.

How to Decalcify your Hair

Decalcifying your hair is vital for keeping it healthy and vibrant, especially in areas with hard water. There are various ways to reduce harmful calcium buildup, including hard water filters, shampooing less frequently, and regular professional treatments. Or, you can just call on Kérastase Première.

The Première line-up has been specifically formulated to decalcify hair fibres using citric acid and glycine – giving your hair a mineral detox. There’s also a salon-exclusive treatment for the ultimate hair decalcification.

The professional ritual involves applying the Concentré, followed by the Bain, a rinse, and then the Kérastase Concentré Liquide Resurfaçant with the Masque before another rinse. This layering technique maximises exposure to citric acid and glycine, delivering intense decalcification while restoring shine and softness. The result? Stronger, healthier, and shinier hair.
