As we edge closer to spring, updating your wardrobe isn’t the only way to freshen up your look. Pastel hair colour is an excellent way of adding an innovative twist to your hair style. The trend for pastel coloured hair has been around for a while and celebrities such as Haylie Baldwin, Kylie Jenner and Lady Gaga have nailed the look in recent years, perpetuating the trend. Dusky pink had its moment in the spotlight last year, but with a myriad of rainbow-like shades to choose from, pastel blue hair seems to be stealing the show right now. With shades ranging in brightness from bold cobalt to icy blue, there are many ways to rock this look!

We’ve almost exhausted the variations on blonde, brunette and red hair, and it’s easy to see why we’re getting more experimental and imaginative with our hair colour. The beauty of pastel blue hair is that it is usually achieved through temporary dye after the hair has been bleached. This means that after a few washes, the blue will disappear, making it ideal for those looking to test out this hair trend, but not commit fully to a such a bold change. More permanent options are available for those who fall in love with their dreamy blue locks.

To help you in your pursuit of the perfect blue shade, we’ve put together some of the best pastel blue hair color ideas you’re sure to love.
