The Best Pastel Hair Dyes

By Hannah Liddle - 1 year ago | Updated

Sometimes, all we need to do is go out with the old and in the new; we need to give our flat a good Marie Kondo, wave goodbye to the tat we've been hoarding for the past God knows how long and just start afresh. And what better way to celebrate this notion than with a new hairstyle? We’re thinking fresh, pastel colours that spark joy and celebrate individuality.

Whether you’re wanting to go pretty pink, baby blue, pale green or lilac, we’ve rounded up the very best temporary and permanent hair dyes to help you rock the pastel hair trend.

But before we get ahead of ourselves, there's one thing you may need to consider first: will you need to lighten your hair? If you’ve got brown or dark hair, you’re going to need to bleach your current colour so that the pastel dye will take properly. Try this BLEACH LONDON Total Bleach Kit that gently lightens your locks and prepares it for the pastel dye.

1. Pastel pink

Lime Crime Unicorn Hair Tint

Pink is by far the most popular pastel hair colour… I’ve even tried it out myself and loved it! We’ve seen pastel pink hair on the likes of Cara Delevingne, Rihanna and even Dame Hellen Mirren and it’s certainly a colour for the bucket list.

So if you haven’t tried out this candyfloss hair colour, then pick up a bottle of Lime Crime’s Unicorn Hair in Bubblegum Rose. It’s incredibly pigmented and, like all Lime Crime’s hair dyes, it’s a damage-free formula that’ll keep your hair wonderfully smooth and shiny.

Revolution Rainbow Drops

Another tip top temporary solution is this wash out formula from Revolution. The rose pink shade lightly colours the hair, is easy-to-apply and delivers a customisable depth and intensity thanks to the dropper system. It’s perfect for testing out a fun shade for an event as you can simply wash out the next day if you’re not fan.

2. Pastel blue

I Heart Revolution Rainbow Shots Hair Colour

If you’re wanting to throw it right back to 1999 when Eiffel 65’s Blue (Da Ba Dee) was a hit, then check out I Heart Revolution Rainbow Shots Hair Colour. Hillary Duff did the pastel blue hair and she looked 50 shades of CUTE. It’s vibrant, fun and a colour that suits all aesthetics…you just have to be brave enough to give it a go.

Revolution Hair Tones For Brunettes

Working on both light and dark hair colours, this temporary hair dye is the perfect way to jazz up your locks. Whether you're applying it to a full head or just the ends for a blue balayage effect, it gives a bright and striking colour that looks pretty darn kick-ass.

Brush on as much or as little as you like to achieve different shades of blue. Oh, and you'll be pleased to know this particular formula lasts up to 2-15 washes, meaning there's no long-term commitment!

BLEACH LONDON Blullini Super Cool Colour

BLEACH LONDON Blullini Super Cool Colour

£6.50

Push yourself out of your comfort zone with this Blullini shade from BLEACH LONDON. It delivers a pop of baby blue that is perfect for festival season. And as a vegan-friendly formulation, it’s ideal for beauty lovers who are searching for cruelty-free alternatives to other brands.

3. Pastel green

I Heart Revolution Rainbow Tones Semi Permanent Hair Colour

Green pastel hair is FTW if you’re wanting super punk vibes and this I Heart Revolution Green Mermaid Waves colour is the perfect way to add a little rock and roll to your look. It’s an uncommon choice for hair colour as it could look like you’ve just stepped out of a chlorine bath pre-bleach.

However, when it’s done properly green looks absolutely wicked…but not like Elphaba from the Tony award-winning musical, more like Kylie Jenner, youngest self-made billionare. Your friends will be green with envy. (Sorry, I had to).

Shrine Drop It Hair Dye Kit

Now, this colour is a blue/green hybrid but that's ok... because it glows under a blacklight. That's right, it's a subtler blue-green by day and a party at night. If you want to go all out with your hair colour, Shrine are the go-to brand, they even have a sea-blue if that floats your boat...

BLEACH LONDON Green Juice Super Cool Colour

BLEACH LONDON Green Juice Super Cool Colour

£6.50

BLEACH LONDON again you ask? But how could we not mention the iconic Green Juice shade? This colour shows up best on very light or bleached hair. Think rich-looking jade green hair which looks sensational even after Halloween is over.

4. Pastel purple

Joico Instatint Temporary Color Shimmer Spray - Amethyst

Joico Instatint Temporary Color Shimmer Spray

£4.04

We understand that transitioning to a bold colour can be a bit of a commitment. If you aren't quite ready to take the plunge, then why not experiment with this temporary colour shimmer spray from Joico? Lasting for up to three full days before fading, it's the ideal formula that lets you test the waters before going all-in. The Amethyst shade transforms locks from boring to bold before settling into a gorgeous pastel purple shade.

BLEACH LONDON Smoky Shampoo

BLEACH LONDON Smoky Shampoo

£7.50

If you're wanting to test the waters before going all-out lilac, then this BLEACH LONDON Smoky Shampoo is a shout. It's a temporary pastel colour that's ideal if you're not 100% sure whether purps is for you. With this shampoo, you needn't worry about damaging your hair as it's loaded with nourishing vitamin E. Going purple never felt so good, amirite?

Shrine Drop It Hair Dye Kit

Get creative with your colour and opt for this Shrine Drop It Hair Dye Kit. We’ve seen Nicole Richie work the lilac hair trend back in 2014 (is there a colour that she doesn’t suit???) and Jourdan Dunn in 2015.

You can easily customise your colour with this formula as the dropper gives you total freedom when it comes to application. Whether you go for all-over colour, subtle strands or chunky highlights, it’s certainly a striking and fierce colour that looks amazing on darker skin tones.

5. Rose gold

L'Oreal Paris Colorista Permanent Hair Dye Gel

Rose gold is a safe bet when it comes to dying your hair pastel as you don’t have to fully commit to a bright colour but can still work a subtle hint of pink. It’s the perfect pastel shade for those of you who perhaps can’t go OTT because of work, but want to show your fun side.

L'Oreal provide the goods with this pretty and playful pastel hair dye gel that’ll take your tresses from drab to fab! Iskra Lawrence worked it and oh boy, did she look stunning!

Garnier Olia Bold Permanent Hair Dye

Want to make a permanent switch to a rose gold hue? Look no further than this deep rose quartz hue from Garnier. Loved by professional hair stylists around the globe, this nourishing formula adds a gorgeous shine to your hair.

6. Pastel peach

BLEACH LONDON Awkward Peach Shampoo

BLEACH LONDON Awkward Peach Shampoo

£7.50

Loving the rose gold but want to take it that one step further? Go apricot with this BLEACH LONDON colour. It’s a warm and lively colour that excellently complements both pale and dark skin tones and we guarantee it’s going to look amazing on you.

It’s also great if you’re testing the waters for a full­-on fiery red or ginger hairstyle. We’re getting serious vibes from this look. I mean, just look at how radiant Busy Phillips is with apricot hair, oh my days.

Lime Crime Unicorn Hair Tint

Pastel? Pfft! Ditch the pretty pastel and go all out neon with Lime Crime's Unicorn Hair in Neon Peach. This vivid colour takes peach hair to the next level and we can't get enough of it (see the top left image below).

It's bright, bold and bodacious and it'll look incredible against all skin tones. This isn't a dye for the fainthearted as it'squite a loud colour, but that's not to say you shouldn't just go for it, you know?! Besides, it's a semi-perm that fades gracefully while keeping your hair in tip-top condition.

Wella Color Fresh Create Semi Permanent Hair Colour

Another vivid option is the Infinite Orange shade from Wella Professionals. This semi-permanent hair colour is ideal for bold beauty lovers who want to make a statement this season! Turn heads with a gorgeous orangey shade with pastelises after each wash.

These colours are a gorgeous way to spruce up your style and to give your look a little bit of ooh-la-la. I mean, why not? You only live once, people.

OK, gotta go – I'm off to dye my hair!
