9 STYLISH HAIR COLOURS FOR SUMMER 2025

With warm, balmy evenings on the horizon and social calendars starting to fill up, now’s the perfect time to experiment with your hair colour.

Whether you’re thinking about lightening your locks or going for a completely different shade, we’ve put together nine of our favourite summer hair colours below to help you steal the show during the sunnier months.

Buttercream blonde hair

Natural-looking and creamy, this ultra-soft wearable blonde shade is perfect as we head into the warmer months.

To keep your blonde looking light and warm, wash and condition with our Go Blonder Lightening Shampoo and Go Blonder Lightening Conditioner for a sun-kissed look without drying your hair out.

Strawberry blonde hair

If you’re already blonde and want a subtle change, shimmering strawberry blonde hair is a great alternative.

This perfectly pretty summer hair colour with light red shades and warm blonde hues is similar to the peach hair trend which took haircare by storm in 2022 – and it’s showing no signs of slowing down.

Pastel pink hair

Summer calls for a pop of pink to refresh your colour and add a little something to your latest Insta story.

This bright summer hair colour looks great styled in girly waves or sleek and straight ‘dos. Just be sure to keep coloured hair hydrated to keep it looking its best - try our Hydrate & Recharge Deep Soak Masque once a week for an instant boost of moisture.

Blue and purple pastel hair

If baby pinks aren’t for you but you’re still keen to try pastel shades, try mixing pastel lilac and blue hues to give your hair a summer update. These colours complement each other beautifully, especially when paired with slightly-dark roots and defined brows. 

It's not a look for the fainthearted; these striking shades will certainly add some edge to your summer glow-up. If you need to give your hair a bit of oomph, our Volume Lift Root Booster creates lightweight, lasting lift for a natural-feeling, voluminous style.

Copper hair

You may think of copper as a more autumnal colour – but this rich and vibrant shade is a great hair colour for summer. Think balmy sunsets, golden hour, and shimmering highlights that catch everyone’s eye.

To keep this beautiful colour looking its best, use our Radiant Red Shampoo and Radiant Red Conditioner to prevent bright tones from fading.

Blue ombré

Feeling a little more adventurous? This twist on the classic ombré is the ultimate fun summer hair colour to try out.

With the light blue melting into your natural shade, this experimental hue may not be as scary as an all over colour change - and your stylist will be able to advise you which shade of blue will look best.

Bronde balayage

To supercharge your dark hair whilst not going fully blonde, bronde balayage - a mixture of brown meets blonde - is the perfect summer hair colour for brunettes, as it introduces a multidimensional depth that can't be achieved with traditional foils or highlights.

To keep your blonde strands looking fresh and standing out, use our Highlight Activating Moisturising Shampoo and Highlight Activating Moisturising Conditioner.

Blonde hair with dark roots

It was once a blonde faux-pas to have your darker roots showing through – but now it’s a trend the A-listers can’t get enough of.

This low-maintenance style can even help brighten your complexion, so enjoy your peek-a-boo roots throughout the summer months. If you fancy a change and your roots are too dark for your liking, just spritz some of our Go Blonder Controlled Lightening Spray on to wet hair to blend your roots into your lengths.

Jet black hair

For darker brunettes who crave a seriously stand-out colour this summer, dare to go jet black.

To achieve this eye-catching shade, use our non-drip Precision Foam Colour in Luminous Natural Black for even coverage. If you’re a newbie to colouring your own hair, discover all our top tips for dyeing your hair at home.
