Purple shampoo revolution: k18 unveils foam that revives hair color – even grey

That blonde phase? Yeah, I know the feeling. Small-town well water and a sudden, aggressive shift to yellow was a brutal lesson learned. But trust me, the struggle doesn’t have to end with a dull, brassy disaster.

Introducing k18’s triplebright oxidation defense purple shampoo foam

K18, the brand that’s become a cornerstone of my colour routine – seriously, their mask and dry shampoo are miracles – just dropped something groundbreaking: a foam purple shampoo. And celebrity colourist Rachel Bodt, who’s worked with Beyoncé, Lorde, and a whole host of other luminaries, is calling it a game-changer for everyone, from blondes to grey.

Bodt explains that this isn’t your standard purple shampoo, just depositing colour to mask yellow tones. “It actually clarifies hair, removing metal and mineral buildup in the hair and preventing further oxidation,” she says. The clever chemistry uses chelating ingredients that bind to those pesky metal ions – the very things that make grey hair brittle and colour appear faded – effectively smoothing the surface and restoring vibrancy. The foam consistency is key; it’s dispensed ready to use, eliminating the need for vigorous rubbing and ensuring even distribution.

“I think we are all guilty of using a very pigmented purple shampoo, and it turns out splotchy or super pigmented in areas of your hair,” Bodt observes. I’ve been there, undeniably. But this foam? It delivers a consistent, uniform tone. I’ve tested it on my red hair, dialing back the vibrancy slightly – leaning toward a gorgeous strawberry shade – and then again to combat brassiness after a recent colour refresh. Brunettes can also benefit, instantly neutralizing unwanted warmth. Just a pump or two monthly is all it takes, and honestly, the results speak for themselves. My strawberry blonde/copper red is looking brighter, more even, and undeniably healthier.

The immediate impact is striking. My red hair, in particular, seems to have undergone a full rejuvenation. It's softer, more nuanced, and far less harsh. It’s not about masking; it’s about restoring the underlying colour. And the texture? Remarkably light. Following the application with K18’s Hair Mask only amplifies the effect, leaving my hair feeling cleansed, moisturised, and unbelievably soft.

Let’s be honest, it’s expensive. But considering the longevity of a single bottle – I’m rationing it religiously – it’s an investment. I used to be a blonde obsessed, constantly chasing that icy hue. Now, I’m genuinely thrilled with the depth and richness of my red. It’s a testament to K18’s innovation and a reminder that even the most stubborn colour issues can be addressed with the right approach. Forget muddy results; this is a truly transformative experience.”
