We’ve all had that moment in front of the bathroom mirror. You lean in a little closer, part your hair on just the right angle and wonder, “Is that a grey?”
For some, it’s a surprise. For others, it’s simply another milestone to embrace. And while we’re firmly in favour of ageing on your own terms (after all, some of the most stylish women we know wear their silver strands with pride), choosing to cover greys is just as personal.
Whether you choose to cover your greys regularly or are simply looking to stretch the time between salon appointments, maintaining healthy-looking hair while still feeling our best remains the priority.
Thankfully, a new wave of products is making at-home grey coverage feel a little less intimidating for those who are looking into a DIY option. Rather than committing to traditional at-home dyes or expensive salon visits every few weeks, brands like Polar Hair Care have introduced an alternative. The Instant Dye Shampoo is designed to deposit colour throughout your hair as if you’re using your regular shampoo, making grey touch-ups a whole lot easier.
Naturally, we were intrigued. Could a shampoo really make grey coverage that effortless? We took a closer look.

Unlike traditional box dyes, Polar’s Instant Dye Shampoo develops in as little as 10 minutes and is applied much like a regular shampoo. The idea is simple: cleanse your hair while simultaneously touching up your roots, without the mixing bowls, brushes or lengthy application process that often comes with at-home dye kits.
How To Use
- Lather: Pump onto your hands and lather well.
- Apply: Spread evenly on dry hair and leave for ten minutes.
- Rinse: Rinse thoroughly and enjoy your new colour.
Can A Shampoo Really Cover Grey Hair?
At first glance, the idea of a shampoo replacing your regular hair colour routine sounds almost too good to be true. But unlike a traditional cleansing shampoo, Polar’s Instant Dye Shampoo contains colour pigments that develop as the product sits on the hair.
Applied to dry hair and left for around 10 minutes before rinsing, it works much like a semi-permanent colour treatment, helping blend and cover grey strands while leaving your overall shade looking more even. Because the formula gradually fades over time, it’s intended to be reapplied every four to six weeks, depending on how much grey regrowth you have or how rich you prefer your colour to look.
The biggest difference comes down to the application. Rather than mixing multiple components or sectioning your hair with a brush, the product is applied just like a shampoo, which may appeal to anyone looking for a less complicated colouring routine.
As with any colour-depositing product, it’s still recommended to avoid light-coloured towels until the hair has been thoroughly rinsed.

How Is Instant Dye Shampoo Different From Traditional Hair Dye?
While there are plenty of at-home hair colour options available, most still involve the familiar process of mixing dyes, carefully applying colour section by section and hoping you haven’t missed a spot.
Polar takes a different approach by turning the colouring step into something that looks much more like your regular wash routine. The formula is designed to be massaged through the hair like a shampoo before being left to develop, rather than requiring the more precise application that traditional box dyes often call for.
It’s also intended to be used only when your colour needs refreshing, rather than replacing your everyday shampoo. That means you can continue with your usual hair care routine between applications while using the Instant Dye Shampoo to help maintain your chosen shade and blend new grey growth as it appears.
For anyone looking for a lower-maintenance approach to grey coverage, it’s an alternative to consider, particularly if regular salon visits or traditional at-home colouring feel too time-consuming.
