There is something wonderful about summer in London. The parks fill up, the pub gardens come alive, and there is a general feeling that the whole city has exhaled. But if you have ever tried to keep your hair looking polished through a hot London summer, you will know it is not always the easiest season for your strands.
Between the sun, the humidity, the pollution, the chlorine from a rooftop pool day, and the salt from a weekend by the sea, summer asks a lot of your hair. Add in the fact that most of us are outdoors more, styling less, and generally living life at a slightly more relaxed pace, and it is easy for hair to end up looking dry, dull, or a little worse for wear by the time September rolls around.
Here are our best summer hair care tips from The Hair Club London, designed to keep your hair looking healthy, your colour looking vibrant, and your styling feeling effortless all season long.
What Summer Actually Does to Your Hair
Before we get into the tips, it helps to understand what you are actually up against. Summer damage tends to come from a few key sources.
UV Exposure
UV rays are just as damaging to your hair as they are to your skin. They break down the proteins in the hair shaft, fade colour, and leave hair feeling drier and more brittle over time. If you have coloured hair, this is particularly worth taking seriously, because sun exposure can undo an expensive salon appointment faster than you might think.
Humidity
London summers are not the most humid in the world, but on a warm, sticky day the humidity is more than enough to send frizz-prone hair into overdrive. Humidity works by drawing moisture into the hair shaft, causing curls to expand and smooth styles to lose their finish.
Chlorine and Salt Water
Whether you are doing lengths in a lido, cooling off in a hotel pool on holiday, or swimming in the sea, both chlorine and salt water are drying and can cause colour to fade or shift. Blondes in particular need to be careful, as chlorine can react with lightened hair and give it a slightly green tinge.
City Pollution
This one is easy to forget, but London air carries a fair amount of pollution, and it settles onto your hair and scalp just like it does on your skin. Over time, it contributes to dullness, buildup, and a scalp that feels less than fresh.
Your Summer Hair Care Essentials
Here is how we recommend approaching the season, whether you are spending it in Battersea Park, on the balcony of a rooftop bar, or somewhere further afield.
Prioritise Hydration
Summer hair is thirsty hair. The single most impactful thing you can do is prioritise moisture. That means using a hydrating shampoo and conditioner, adding a weekly hair mask into your routine, and considering a professional hydrating treatment in the salon as part of your regular appointments.
Our conditioning treatments are a lovely add-on for summer, and the hydrating option in particular is designed for exactly this scenario, replenishing moisture that the sun and city life have quietly stripped away. It takes just fifteen minutes and can be added to any cut or colour appointment.
Protect From UV
You would never dream of spending a hot day out without SPF on your skin, but hair protection is just as important and much easier to overlook. Look for a leave-in spray or lightweight oil that contains UV filters, and reapply throughout the day if you are outdoors for extended periods. Wearing a hat when you can is another simple but effective option, particularly on the hottest days.
Rinse Before You Swim
This is one of the best-kept secrets of summer hair care. If you wet your hair with clean water before you get into a pool or the sea, your hair absorbs less of the chlorine or salt water because it is already saturated. A leave-in conditioner or a light oil applied beforehand adds another protective layer and can genuinely save your colour.
Wash Off the Day
After a day in the sun, at the pool, or wandering through the city, a good wash matters more than usual. Look for a clarifying option once a week or so to remove buildup, pollution, and product residue. Our SDL Detox treatment is specifically designed for this, offering a deeper cleanse that removes impurities and leaves the scalp feeling genuinely fresh again.
Looking After Coloured Hair in Summer
If you have invested in your colour, protecting it through summer is essential.
Extend Your Wash Cycle
Every wash lifts a small amount of colour, so stretching the time between washes helps your colour last longer. Dry shampoo is your summer friend here, refreshing roots without a full wash.
Use Colour-Safe, Sulphate-Free Products
Sulphates are drying and colour-stripping, and combined with sun exposure, they can fade your colour noticeably faster than you would expect. Investing in the right shampoo and conditioner is one of the highest-impact things you can do for coloured hair in summer.
Book a Toner Refresh
If you are noticing your blonde is warming up, or your brunette is looking a little less rich than it did, a toner appointment is a quick, affordable way to bring your colour back to life without committing to a full colour service. It takes under an hour and can completely reset how your hair looks. If you would like to read more about maintaining colour between appointments, our guide on how often to book a regrowth tint covers this in more detail.
Styling Tips for London Summers
Realistically, most of us are doing less styling in summer, which is not a bad thing. Here is how to embrace the season without sacrificing polish.
Lean Into Air Drying
Summer is the perfect time to give your hair a break from heat styling. Wavy and curly hair often looks its best air-dried in warm weather, and even straight hair can benefit from occasional heat-free days. If your natural texture is something you are still figuring out, a wet cut is a lovely option, as it shapes the hair without a blow dry finish and gives you a haircut that works with your air-dried texture.
Master the Easy Updo
A loose, low bun or a soft ponytail is a summer hero style. It keeps hair off your neck on the hottest days, looks polished with next-to-no effort, and protects the ends from constant sun exposure. Practising a couple of go-to styles at the start of summer means you always have an easy answer on a busy day.
Trim Regularly
Split ends are more visible on dry summer hair, and they make hair look worse than it actually is. A regular trim every eight to ten weeks keeps everything looking healthy and stops damage from travelling up the hair shaft.
A Word on Holidays
If you have a holiday coming up, a little bit of prep goes a long way. Book any colour or treatment appointments at least a week before you travel, pack travel-sized versions of your best products (particularly a leave-in and a UV protectant), and consider a bond-strengthening treatment like K18 before you go if you know you will be in the sun a lot. Your post-holiday hair will thank you.
Summer in London is wonderful for a lot of reasons, but it does ask a fair bit of your hair.
Prioritising hydration, protecting from UV, rinsing before you swim, and adjusting your routine to include a proper clarifying wash once a week will keep your hair looking its best all season. If you have coloured hair, sulphate-free products, less frequent washing, and the occasional toner refresh are your best friends. And on the hottest days, embracing your natural texture and mastering an easy updo is often the most stylish choice of all.
