Warm weather, humidity and increased sweating can all make your hair feel oily more quickly during summer. If your roots feel oily or your hair looks flat by midday, you’re not imagining it – the scalp naturally produces more oil in heat. With a few targeted adjustments, you can keep your hair feeling fresh, balanced and clean throughout the warmer months.

Switch to a Lightweight, Balancing Shampoo

The shampoo you choose sets the tone for how your hair behaves throughout the day. In summer, the scalp produces more oil as it reacts to heat and humidity, so using a shampoo that’s too rich can accelerate greasiness. A lightweight, balancing formula helps regulate oil production without stripping the scalp – which is important, because over-cleansing can trigger more oil as the scalp tries to compensate.

Look for:

• Balancing or volumising shampoos that lift at the root
• Clarifying shampoos once a week to remove sweat and product build-up
• Sulphate-free formulas that maintain a healthy scalp environment

A well-chosen shampoo can dramatically extend the time between washes.

Condition Only the Mid-Lengths and Ends

Conditioner is essential for keeping the hair soft and manageable, but applying it too close to the roots is one of the fastest ways to create oiliness. The scalp naturally produces oils, so adding extra moisture at the root area weighs the hair down and reduces volume.

Apply from:

• Ear level downward
• Never directly onto the scalp

This keeps the lengths nourished while allowing the roots to stay light, lifted and fresher for longer.

Rinse Thoroughly

Even the best products can leave hair looking oily if they’re not rinsed out properly. Residue from shampoo or conditioner can cling to the scalp and mimic oil, especially in warm weather when sweat mixes with leftover product.

Tip:

• Rinse for at least 30 seconds longer than usual.
• Focus on the root area and ensure the water runs completely clear.
• This simple habit often makes a noticeable difference to how clean and airy your hair feels.

Avoid Touching Your Hair

Hands carry natural oils, SPF, sweat and environmental residue – all of which transfer easily to the hair. In summer, when skin is naturally more hydrated and sunscreen is used daily, this transfer happens even faster.

Try:

• Wearing your hair up on hot days
• Using clips or accessories to keep hair off your face
• Avoiding the habit of running your fingers through your hair

Reducing contact helps maintain freshness and volume throughout the day.

Use Dry Shampoo Correctly

Dry shampoo is a summer essential, but many people use it reactively rather than proactively. Applying it before your hair gets oily helps absorb oil as it forms, keeping the scalp fresher for longer. We recommend our K18 AirWash Dry Shampoo, or our Kevin Murphy Fresh Hair Dry Shampoo.

How to use it:

• Apply to clean, dry hair before oil appears
• Spray at the roots in small sections for even coverage
• Leave it to absorb for 2–3 minutes
• Massage in and brush through to distribute

Used correctly, dry shampoo adds volume, texture and longevity to your style.

Wash Your Hairbrush Regularly

Hairbrushes collect oils, product residue, dust and sweat – and if they’re not cleaned all that gets redistributed back into your hair. In summer, when oil production increases, this becomes even more noticeable.

• Clean weekly using warm water and a gentle shampoo.
• Remove trapped hair first, then allow the brush to air dry fully.
• A clean brush supports a clean scalp.

Choose Lightweight Styling Products

Heavy creams, oils and serums can weigh the hair down and make it appear oily, especially in warm weather. Lightweight formulas give movement and lift without contributing to oiliness.

Opt for:

• Lightweight mousses
• Volumising sprays
• Fine mists instead of thick serums
• Products designed to add lift at the root

This approach keeps your hair feeling fresh, airy and full of life – even on the warmest days.
