There’s almost nothing more ‘modern millennial’ than that niggling desire to experiment with your hair colour. Over the past few years, social media, the blogosphere and hair consultants have all touted the benefits of creative self-expression through fresh, bold hair colour.

For those of you that are still weighing up your bold colour options (and for those of you seeking to maintain your shade), we’ve rounded up a few of our must-have tips for total bright hair dye success.

Going for a bold hair colour statement

There are many factors to consider when choosing a shiny new hair colour, particularly when that colour is a bright one. This should come as no surprise, but choosing a high-quality dye is incredibly important for your hair’s safety and health.


The experts at Garnier have discovered that oil not only conditions your individual hair follicles, but, when concentrated inside a colour dye, can help boost colour performance as well – offering an unparalleled intensity of colour in a permanent dye solution with no ammonia for a pleasant scent. Products like the Garnier Olia Bold range are perfect for imparting a power-packed dose of look-at-me-now colour, while also being ammonia free! The collection contains a beautiful spectrum of options from deep violet to vibrant orange – including our favourite colour of 2020: Rose Gold!


Alternatively, our Nutrisse Ultra Colour vibrant hair dye that provides intense colour on all hair textures, and even dark hair, could be perfect for you. This range includes exciting colours such as Midnight Blue, Vibrant Red, Copper Passion and even Intense Lilac for the most intense vibrant colour.

Choosing and using a new colour

What shade you choose for your new look should be carefully considered, particularly if you’re not interested in bleaching your hair first. We admit, to achieve your dream look, sometimes bleaching is necessary. That said, if your ideal shade is less simple to pin down, we’d always encourage you to work with the shade you naturally have when considering your new colour choices.Another option is to use our Nutrisse Ultra Colour vibrant hair dye, that works on even dark hair, without having to bleach first. This hair dyes unique technology saves you both time and money by not having to use bleach and provides and intense, long-lasting colour that you will love!


For example, if you have dark brown hair, it’s very unlikely that a bright red will come out looking exactly as you envisioned. A violet red, on the other hand, is just the thing to make your colour pop.


If you’re a blonde looking for a change, we can’t say ‘rose gold’ enough. It’s a beautiful, easy to wear shade that’s perfectly on trend for summer chic vibes – the perfect blend between red, blonde and an ethereal springtime hue.

Keeping it bright

Once you’ve undergone the metamorphosis into bold-haired beauty, there are a few key pieces of maintenance to ensure that your colour stays vibrant and your hair stays healthy.

Opt for quality

Just like with the colour itself, choosing high-quality after-colour products is incredibly important for healthy hair maintenance. Garnier Ultimate Blends Argan Oil and Cranberry Extracts range offers a shampoo, conditioner and hair treatment mask that makes an excellent trio of expertly formulated products to help keep your coloured hair bright and shining.

Stay out of the heat

If hair colour had an arch-nemesis, it would certainly be heat. Ask any seasoned hair colourer and they’ll all say the same thing: nothing strips hair colour faster than too much heat. To help avoid it, a top tip is to air dry your hair (or at the very least, use a heat protectant and a low heat setting on your hair dryer).


If you can stand it, another really simple way to discourage your colour from fading is to wash your hair under cool water. We know, but trust us, this one makes a big difference to the overall vibrancy of your colour – plus, it’s great for your circulatory system and is most definitely a wake-up call! Heat, in any form, opens up the outer layers of your hair follicles which means that the colour locked in at the core of each strand is less protected, running a higher risk of drying out and the colour dissolving away.

Try going dry

Dry shampoo is also a freshly-coloured hair’s best friend. The more you can reduce the time you spend fussing with your hair, either in the shower or with styling, the higher the chances you have of keeping your new colour for longer. Dry shampoo is not only handy for excess oil absorption, but it’s also a total time saver.


There’s something really exciting about dyeing your hair. You can create a whole new look, feel like a completely different person, and get a fresh perspective on your style and makeup routine.


However, there’s nothing quite like that gut-wrenching moment when you take the towel off your head, look in the mirror and realise that your chosen home hair colour is totally different to what it looked like on the packet.


There are several reasons why home hair problems arise. No matter how many ‘how to dye your hair’ articles you read beforehand, these things happen. But whatever the cause of your less-than-ideal hair colour reaction, there is a solution.

How to adjust colour that’s too dark

For the moments when your vision of chocolatey-brown turns into a lack-lustre charcoal, there’s a pretty simple fix - wash it out.


The trick is to use a shampoo that isn’t a ‘colour protecting’ one, as it helps to strip your hair of any unwanted colour and lift it back to its lighter tones. It also helps to add a little bit of soap into the mix too.


You’ll need to apply an intensive hair mask after you’ve finished rectifying your colour though, as your hair is likely to be drier than usual. We love our Hair Food 3 in 1 Banana. It’s enriched with natural extracts, keeping your colour vibrant and your hair soft wash after wash.

How to adjust the shade when your hair is too red

Most brunettes have had a vision, at some point, of having some feisty red undertones that shimmer in the light, but with home hair dye it can sometimes go wrong.


If the finished colour is more fire engine than sultry maven, try dyeing your hair again with a shade of brown that’s at the same colour level as the red you used. For example, if you were aiming for a deep red, but it went too far, the Garnier Nutrisse 3.23 Dark Quartz Brown Permanent Hair Dye will help to even it out. Leave the hair dye on for five to ten minutes and keep checking the colour so you don’t overcook it. When you’re happy with your new shade, simply wash it out and go.

How to adjust the shade when your hair is too blonde

It’s happened to us all. You decide to turn your blonde locks a shade or two lighter, but, during your big reveal, you find that your hair has turned almost totally white. If this happens to you, don’t panic. The solution is very simple - dye your hair a few shades darker.


If you want to give your hair colour a bit more of a golden tone, the Garnier Nutrisse Creme Gold Pearl Blonde Permanent Hair Dye is a great choice. It will leave your hair looking warmer and feeling nourished. The Garnier Nutrisse Creme 8N Nude Medium Blonde Permanent Hair Dye is perfect for anyone who wants a more multi-tonal look made up of blondes and very light browns. It combines a unique blend of ash, gold and pearl, giving luminous colour that still looks natural.


When you’ve found the right shade to lift your hair, keep it on for half the recommended time. Check how your hair colour is changing every five minutes and take it off when you feel like it’s dark enough.

How to fix brassy hair colour

If you’re venturing from brunette to blonde, it’s not uncommon to find brassy shades in your hair. This is caused as your natural hair colour with have some red and orange undertones. If this happens, a purple or silver shampoo and conditioner will be your saviour. The purple colour infused in the formula works to neutralise the brassy undertones, giving your hair a more ashy finish.


Protecting your colour from fading away

Once you’ve found the right hair colour, it’s important to protect your hair from damage. To do this, look at how often you’re using heated products, washing your hair and exposing your locks to the sun. Always use a good quality shampoo and conditioner such as our Garnier Ultimate Blends Argan Oil and Cranberry Extracts Conditioner for Coloured Hair, which will help to protect your coloured hair.
