The Best Pastel Hair Dyes

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 L’Oréal ParisColorista Bleached Hair Kit that gently lightens your locks and prepares it for the pastel dye.

1. Pastel pink

Lime Crime Unicorn Hair Tint - Bubblegum Rose

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.

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.

3. Pastel green

I Heart Revolution Rainbow Tones Semi Permanent Hair Colour - Green Mermaid Waves

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).

Now, this colour is a darker 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, Schwarzkopf are the go-to brand, they even have a sea-mermaid green if that floats your boat...
