Are you ready to go to the dark side? For many of us, that leap into the unknown is not an easy one. Is it really as simple as it sounds? What if it goes wrong? How ‘permanent’ is permanent? We understand there's an element of trepidation behind every hair colouring decision to go from blonde to brunette, and that's why the Garnier experts created the Nutrisse at home hair colour range to take the worry, hassle and most of the expense out of the process.

Trust us, there is nothing to fear; we've been doing this for a long time. Millions of people across the globe have coloured their hair successfully at home with Garnier. Very, very rarely do we get negative comments, and, if we do, it's usually because the person hasn't followed our advice - so that's our first tip: learn from the experts.


What is permanent hair colour? Well, it's a dye that penetrates the hair shaft and deposits colour directly onto the hair cortex. Permanent colour is bolder, more vibrant and better at covering those silver hairs than temporary hair dye.

It will last longer, too, but not forever, so it's not permanent in that sense. It lasts until it grows out, essentially. It won't fade after washing, but you may need to retouch your roots after 4 to 6 weeks, depending on how fast your hair grows. Very dark hair dye, even if it is permanent, is prone to fade when exposed to environmental 'aggressors', so bear that in mind if you go on holiday as sea, sun and salt are definitely not your friends (nor are chlorinated swimming pools).


When going from blonde to brunette at home– choosing a shade is crucial. The good news is that you're heading in the right direction. Going from light to dark is much easier than the other way around. Think of it like colouring in or decorating; it's always easier to darken a colour than to lighten it.

Traditional wisdom has it that when colouring hair at home you should change by no more than two shades from your natural colour. By and large, that's pretty good advice, but hair colour technology has improved massively in recent years, so if you are desperate to go straight from blonde to black hair, it may only take a couple of home hair colour sessions. One of our favourite home hair dyes for brunettes is Nutrisse Shade 5.0, our Mocha Brown (one of our most loved and best at home hair dyes for brown hair) worn by Davina McCall. Or, even if you fancy going even darker try our Nutrisse Shade 1, our favourite black permanent hair dye. Try on any of our wide ranging brown shades now, with our Virtual Try-On tool.


Whenever you choose hair colour, it's really important to consider your skin tones. If you have 'cool' skin with underlying hints of green, then a dark shade tinged with blue is probably your best option. This colour creates a striking contrast with your complexion and should complement the cool tones in your skin (think Snow White, without the dwarves).

On the other hand, if you have warm skin tones with pinky hues you should consider a shade with a bit of red, like Garnier Nutrisse 3.6 Deep Reddish Brown at home permanent hair dye – sultry but warm.

Picking a shade is not always as easy as it sounds though, which is why we have developed an online Virtual Try-On tool for you to use now, or you can have a go at our Color Match tool, designed to help you find your perfect home hair colour shade.



Once you're happy with the shade, and you've opted for permanent colour, make sure you do a patch test 48 hours before dyeing your hair to make sure you aren't allergic to any chemicals. We understand you're keen to get going and make that change, but patience is a virtue! If you’re not sure about how to apply an allergy alert test – watch our video for easy to follow instructions.



Conduct a strand test 24 hours before colouring your hair. For this, mix a small amount of colour creme and developer creme in a non-metallic bowl and apply to a strand to develop. This was you can test the colour before applying the whole box dye.


Not all hair colour is made the same; changing blonde hair to black hair carries the risk of a greenish end result, which is less than desirable, so only use trustworthy permanent hair dyes. Here at Garnier, we provide a top class at home hair dye that ensures long-lasting colour.


Another common mistake is to underestimate the amount of hair dye you'll need. There's nothing more annoying than running out halfway through the job, especially if you have long, thick hair that absorbs a lot of pigment. You really don't want to end up with blotchy colour or a half-hearted version of what you were hoping to achieve, so why not buy an extra pack just in case. If you don't use it, it'll always come in handy when you’re re-touching your roots.


It's also worth remembering that dyed dark hair doesn't have the natural shine of naturally dark hair. Even with the highest quality home hair dyes, such as ours, whether you like it or not, introduce chemicals that can dehydrate your hair. So, if you want the wow-factor of deep, lustrous shine and vitality, you need to replenish your hair’s moisture and retain as many nutrients as you can. With permanent colour, it's absolutely essential to provide extra ‘TLC’ for your lovely locks. Look for sulphate-free products and deep intense conditioners like the ones in the Ultimate Blends Argan Oil range, developed specifically for keeping coloured hair in ‘tip-top’, healthy-looking condition. Plant-based oils such as argan will nourish your hair and help to reverse your hair’s tendency towards roughness and dullness.

Finally, read the instructions; it might seem obvious but plenty of people don't.

So, here ends your first complete lesson in at home permanent colour; now, it's over to you to have a go at going from blonde to brunette, or blonde to black hair. Whether it’s a full dying experience or just at home hair highlights, colour with confidence, choose well, follow our expert advice and enjoy your amazing new look. Oh, and get a friend to help; a second opinion is always good and it makes it more fun!
