Fact: there's metal buildup in every head of hair. The presence of these metals can make your hair look dull – sometimes even green-ish – and can eventually cause damage.

By purifying your hair and removing the metals, you’ll be able to get the healthy-looking coloured hair of your dreams and make your colour last longer.

Find out more about our Metal Purifier technology below, and how it helps protect your hair in each stage of our Colour Studio 3-step routine.

How do we get metals in our hair?

Tiny particles of metal accumulate on our locks every time we wash our hair, as they’re present in our tap water. The level of metals in your hair is not always easy tell, and different areas of the world have different levels of metals in the tap water. What we can be certain about is that we all have this problem.

So, why are metals in hair harmful?

Heavy metals in your hair don’t always make a visible impact – for example, when they make it dry and brittle. But they can have many noticeable effects.

You might be able to feel the metals in your hair: heavy metals in hair make it dry and brittle. Eventually, metals can even damage the inner structure of the hair and cause breakage. You may also notice a lack of shine, and if you have a higher concentration of metals in your mane, a green-ish tone can be noticeable.

Even when you don’t feel or see their effects, metals can still cause damage to your locks and hinder you from having healthy-looking hair with the colour you desire.

On top of structural damage, the presence of metals in your hair can interfere with the colour result when you dye it. This happens by metals interacting with and decreasing the number of dye molecules that penetrate the hair. This can result in an undesirable colour result with unexpected tones and unevenness.
