How to Make Your Colour Last Longer in Summer 2025

At Hair In The City, we know how much our clients love that fresh-from-the-salon colour. But with summer sun, holidays, and heat styling all in the mix, keeping that colour vibrant can be a bit of a balancing act.

Whether you’re jetting off to the Med or just making the most of the (occasional) Glasgow sunshine, here’s our stylist-approved guide to helping your colour stay looking salon-fresh for longer.

1. Start Strong with Professional Colour

Your colour journey starts with what’s on your hair, and that’s why we only use Keune colour in the salon. As a Keune Ambassador Salon, we trust their formulas to be high-performing, deeply nourishing, and long-lasting. It’s colour with integrity, rich tones, gorgeous shine, and built-in protection. When the foundation is strong, the fade is slower.

And just like we only use the best professional colour, we also recommend the right take-home care. All the Keune products we use at the backwash — from shampoo to treatments — are available to buy in the salon, so you can continue the same level of care at home.

2. Shampoo Less Often, and Smarter

Washing your hair too frequently can strip away both natural oils and your colour. If you’re used to shampooing daily, try spacing it out to every two or three days. And when you do wash, always opt for a colour-safe shampoo. We love Keune’s Care Colour Brillianz range, it’s designed to protect against UV damage and maintain colour intensity.

The best part? This is the same shampoo our team uses on you in the salon, and it’s available to buy during your appointment. It’s the perfect moment to ask your stylist any questions — they know your hair, your colour history, and exactly what will keep it looking its best between visits.

3. Avoid the Heat (When You Can)

Sun, styling tools, and hot showers all accelerate colour fade. Try air-drying your hair when possible, keep showers lukewarm, and if you’re using heated tools, don’t skip the heat protection. Keune’s Style Heat Protect Spray is a firm favourite among our team for a reason — and if you’re unsure how to use it or whether it’s right for your styling routine, just ask. Our stylists are always happy to recommend the right product and show you how to get the most from it.

4. Rinse Before You Swim

Here’s a stylist trick: soak your hair in clean tap water before you jump in the pool or sea. Why? Because wet hair absorbs less chlorine or salt. Think of it like a sponge, if it’s already full, it can’t soak up anything else.

5. Mask It Up Weekly

Coloured hair needs TLC, especially in summer. Treat it to a weekly deep conditioning mask to restore moisture and seal in shine. Our team often recommends Keune’s Vital Nutrition Mask — it’s deeply hydrating and leaves the hair feeling soft, manageable, and protected.

We stock it in salon too, so if you’re already in the chair and wondering what’s right for your hair, it’s the perfect time to chat to your stylist. They’ll help you pick something that suits your texture, colour, and lifestyle, no guesswork involved.

6. Wear a Hat (Yes, Really)

It might sound simple, but physically blocking the sun is one of the best ways to protect your hair. A wide-brimmed hat or even a silk scarf adds instant style while shielding your colour from harsh UV rays.

Final Thought from the HITC Team

Summer doesn’t have to mean faded, brassy colour. With the right products, a bit of extra care, and some savvy styling tips, you can keep your colour vibrant, shiny, and beautiful right through to autumn.

And remember, our stylists are here to guide you. Every hair type and colour is different, and our team knows exactly how to help you protect your investment. Whether you need advice, a product recommendation, or a full summer haircare routine, just ask. We’ve got you.

You’re always welcome to pop into the salon for a chat about which products are best suited to your hair, whether you’ve got an appointment or not. And if it’s time for a refresh or a seasonal treatment, we’d love to see you back in the chair. Our stylists are experts in colour care and happy to help you choose the perfect homecare to keep your colour glowing until your next visit.
