How to Keep Your Hair Hydrated This Summer - John Masters Organics UK

Why Summer Dries Hair Out

Heat and humidity might seem like opposites, but both can disrupt your hair's moisture balance. Hot, dry air pulls moisture from the hair shaft, while humidity causes the cuticle to swell and frizz. Add in salt water, chlorine, and more frequent washing, and it's easy to see why summer is one of the hardest seasons for hair hydration.

Understanding this helps you build a routine that works with the season rather than against it.

Wash Less, Hydrate More

It's tempting to wash your hair more often in summer — especially after a swim or a sweaty day. But frequent washing strips the hair of its natural oils, which are your first line of defence against dryness.

Try to stretch washes where you can, and when you do wash, use a gentle, nourishing shampoo that cleanses without over-stripping. Our Daily Nourishing Shampoo with Citrus & Geranium is a good option for everyday use. Follow up every single time with a conditioner — this step is non-negotiable in summer.

Make Conditioner Your Best Friend

If you're only using conditioner occasionally, summer is the time to change that habit. A good conditioner helps to smooth the hair cuticle, lock in moisture, and make hair easier to detangle after a day outdoors.

Our Deep Moisturising Conditioner with Lavender & Avocado is particularly well suited to summer — apply it from mid-lengths to ends, leave it on for a few minutes, then rinse. For colour-treated or very dry hair, our Repair Conditioner with Honey & Hibiscus is worth keeping to hand too.

Add a Weekly Deep Treatment

Once a week, swap your regular conditioner for a deeper treatment. This gives your hair a more intensive moisture boost and helps address any dryness that's built up over the week.

Apply after shampooing, comb through from mid-lengths to ends, and leave on for at least five to ten minutes before rinsing. Wrapping your hair in a warm towel while it works makes a noticeable difference.

Use a Leave-In for Extra Protection

A leave-in is one of the easiest ways to maintain moisture between washes. Our Leave-In Conditioning Mist with Green Tea & Calendula is lightweight enough for daily use — spritz onto damp hair before styling to help keep it smooth and manageable throughout the day.

For drier hair types, a few drops of our 100% Argan Oil applied to damp ends adds an extra layer of nourishment and helps tame frizz without weighing hair down.

Rinse After Swimming

Salt water and chlorine are two of the biggest culprits for summer hair dryness. If you're swimming regularly, try to rinse your hair with fresh water as soon as you get out — this helps remove residue before it has a chance to dry on the hair shaft.

Follow up with a conditioner or leave-in treatment to restore moisture quickly. Our Nourishing Defrizzer for Dry Hair works well here too, particularly if humidity is making your hair unruly after a swim.

Protect Your Scalp Too

It's easy to focus on the lengths and ends, but your scalp needs attention in summer too. A dry or irritated scalp can affect the overall health of your hair, so keep it clean, balanced, and hydrated.

If you notice your scalp feeling tight or flaky in summer, our Scalp Purifying Serum with Spearmint & Meadowsweet or the Scalp Exfoliating Scrub with Sugar Cane & Tea Tree Oil can help restore balance as part of your weekly routine.

Adjust Your Styling Habits

Heat styling on top of summer heat is a recipe for dryness. Where possible, embrace more natural styles — air drying, loose braids, or low buns — and give your hair a break from hot tools. If you do use heat, always apply a protective product first and keep the temperature as low as you can.

The Simple Summer Rule

If there's one thing to take away, it's this: hydration in, heat out. The more moisture you can put into your hair — through conditioners, treatments, and leave-ins — and the less heat and harsh products you expose it to, the better your hair will look and feel all summer.

Small, consistent habits make the biggest difference. Start with one or two changes and build from there.
