Whether you’re swapping the Australian winter for a European summer or escaping to Far North Queensland, you may be ready for the heat – but your hair might need a little extra help. That’s because warm, humid weather can make frizz appear fast – and, when there is more moisture in the air, your hair can feel harder to style and keep in place.

If you want to know how to stop frizzy hair in humidity, the answer begins with hydrating hair care, like our Gloss Absolu collection. Designed for long hair prone to frizz, each product is formulated with hyaluronic acid, glycolic acid, and wild rose oil to help deliver lasting gloss, hydration, and smoothness to your hair – and keep frizz at bay during warm weather.

Flying soon? Read on to explore how to protect your hair while travelling with our expert travel hair care tips and the best products for humid climates.

Why does humidity make hair frizzy?

Humidity makes your hair frizzy because the extra moisture in the air enters the hair fibre, causing each strand to swell and lose its smooth shape. When the outer cuticle – the hair's protective layer – lifts as a result of dryness or damage, that process happens even faster.

That's why beach days can be particularly unforgiving, especially in humid coastal locations like the Whitsundays or Hamilton Island. Salt water and sun dry out the hair while humid air causes it to swell, creating the perfect conditions for frizz.

Do all hair types get frizzy in humid weather?

All hair types can get frizzy in humid weather, but damaged hair is usually affected faster – especially if your hair has been exposed to consistent heat styling or chemical damage from bleaching and colouring.

That said, curly hair types are naturally prone to frizz. Because curls bend and coil, the natural oils from your scalp cannot travel down the hair shaft as easily. This can leave lengths feeling drier, which makes the cuticle rougher and gives humidity an easier way in.

How to stop frizzy hair in humidity: 7 holiday hair care tips

Read on to discover our seven expert travel hair care tips and best anti-frizz products, so you can spend less holiday time smoothing flyaways – and more time enjoying the view.

1. Switch to a hydrating shampoo and conditioner

Shampoo and conditioner are your first line of defence against humidity – and a great opportunity to flood your hair with much-needed moisture.

Our best shampoo for humid climates is the Gloss Absolu Hydra-Glaze Illuminating Shampoo. Ideal for long, frizz-prone hair, its high-foaming, gel-like texture is formulated with hyaluronic acid, glycolic acid, and wild rose oil to deeply cleanse your scalp while laying the foundation for an ultra-sleek finish.

Do you have thick hair? Reach for our Gloss Absolu Crème Hydra-Glaze Shampoo instead. Its richer texture penetrates deeper into each strand, delivering the level of moisture that thick hair needs to feel nourished and smooth. Follow that with our Gloss Absolu Insta Glaze Conditioner. Its creamy consistency helps plump your lengths with hydration, making hair easier to detangle and leaving you with holiday-ready glossy, shiny hair.

2. Use a hair serum for humid weather

Humid, heavy holiday evenings call for our Nutritive Magic 8H Night Serum, which you can apply to dry or damp hair before bed. Formulated with anti-dryness polymers – as well as star ingredients niacinamide and glycerin – it helps hydrate and moisturise dry hair to leave your hair easier to manage by morning.

The Nutritive Magic 8H Night Serum is one of our best hair serums for humid weather, with 94% of users noticing less frizz after the first use¹. What’s more, it is a low-effort travel step that works while you sleep – so you can wake up with smoother-feeling hair, without adding extra styling time to your holiday routine.

3. Lock in nourishment with a hair oil

A hair oil is one of the most valuable travel items you can pack – versatile, lightweight, and ready to treat frizzy hair the moment humidity strikes.

That’s why we recommend our Gloss Absolu Glaze Drops High-Gloss Lightweight Hair Oil. It delivers up to 100 hours of frizz protection², coating each strand to leave behind an irresistible, glossy shine. Use it on damp hair before styling or sweep a few drops through your lengths mid-afternoon for an instant touch-up. Small enough to slip into any bag, it's an on-the-go essential that will make hair care while travelling effortless.

4. Style with heat protectant

There's nothing quite like getting ready for dinner as the sun dips low after a long day at the beach or by the pool. In these moments, you want your hair routine to be quick, easy, and foolproof – and Gloss Absolu Anti-Frizz Glaze Milk All-In-1 Spray can help.

It detangles, hydrates, and smooths in one effortless step, delivering 230°C of heat protection and high humidity defence. Spritz it through your hair before reaching for your styling tools to shield strands from heat damage – or apply it before heading out for the day to create an invisible barrier against moisture and frizz.

5. Tame unruly locks with an anti-frizz styling cream

Humidity can make your style drop quickly because moisture in the air changes the way your hair holds its shape.

Before blow-drying, work the Gloss Absolu Frizz-Glaze Styling Cream through damp hair to waterproof strands by up to 98%³. Its silicone-free, creamy formula is one of the best products for humid climates – delivering real hydration (rather than a surface-level fix) and working especially well for thick hair that needs extra nourishment to stay manageable.

6. Dry your hair properly before going outside

Your hair is most vulnerable when it is wet. Stepping outside with damp strands is an open invitation for humidity to move straight in, making frizz almost inevitable.

Always ensure your hair is completely dry before heading out. And if you're planning a day between the pool and the beach, consider bringing a hair oil or serum to apply each time you get out of the water. Reapplying a small amount creates a protective layer over your hair shaft, helping to minimise moisture absorption before it has a chance to take hold.

7. Apply a hair mask when your hair feels dry

Our final travel hair care tip is to pack a hair mask for the days your hair needs a quick moisture reset. Between plane air, chlorine, salt water, sun, and humidity, your lengths can start to feel dry, fast – and a mask is an easy way to bring hydration back without overcomplicating your routine.

Work the Gloss Absolu Crème Hydra-Glaze Mask through your lengths, leave for five minutes, then rinse. Its rich, creamy texture delivers a high concentration of hydrating ingredients while keeping hair feeling lightweight and silky. This mask also doubles as a quick fix after a day in the ocean or pool as it draws out chlorine and salt residue without the need for the rest of your routine – ideal if you're mindful of how often you wash your hair.
