How To Keep Hair Straight In Humidity

It can sometimes feel like we’re constantly waiting for warmer days to arrive - especially living in Britain! So whenever the heat (and humidity) does finally show up, we’re not letting frizz take over. Here’s your go-to guide for keeping hair smooth, sleek and beautifully polished, whether you’re in the UK or abroad, no matter how humid it gets. ✨

What Makes Hair Go Frizzy?

We’ve all been there: you leave home with smooth, spot-on hair that’s been dried and straightened to perfection, only for flyways to appear within half an hour of leaving the house. 😖

Hair becomes frizzy when the level of humidity in the air is more than the level of water in your hair. Even when your hair feels dry, it still contains water within its inner structure. When the air is damp, your strands naturally try to balance things out by absorbing that extra moisture. As humidity seeps in, it disrupts the delicate bonds that hold your style in place, especially hydrogen bonds, which are easily broken and reformed. That’s why straightened hair can quickly bend, wave or puff up.

And when you’re somewhere warm and tropical? It happens faster. Hot, steamy climates mean higher humidity levels, so hair absorbs moisture more quickly, turning poker-straight strands into soft waves or full-on frizz even faster.

Top Tips To Keep Hair Straight In Humidity

Humidity doesn’t have to mean waving goodbye to sleek, straight hair. With the right prep, products and a few smart styling tweaks, it’s completely possible to keep your hair smooth, polished and frizz-free, even when the air feels thick and sticky. These top tips will help you lock in your straight style, protect it from moisture in the air, and keep your hair looking effortlessly put-together, whatever the weather’s doing.

Preparation Is Everything

Heat-styling your hair is key to achieving smoother, frizz-free hair that can handle humid weather, so make sure that you choose a product that combines frizz-fighting with protective hair benefits. Especially when you’re on holiday and exposing hair to a damaging mega-mix of dehydrating salt, sun and chlorine. Using a nourishing shampoo and conditioner every wash builds hair’s resilience and will make prepping the hair for humidity way easier when the time comes.

Seal Your Strands

Applying a hair serum product is a great way to deal with humidity, helping to flatten the hair cuticle for a smoother look, and sealing the ends to prevent annoying flyaways. Our pink elixir is a luxe take on a serum, infused with a combo of silky precious oils that support the hair’s own keratin. The pay-off? Stronger, shinier, straighter and frizz-free hair.

Style It Out

One anti-frizz product you should never be without is our incredible Effortless Anti-Frizz Hair Spray. Applied before heat-styling it acts like a lightweight, invisible veil on the hair, effectively protecting every strand from environmental aggressors and keeping hair looking smooth and glossy. Even better, it fights frizz for up to three washes, so your hair looks great for way, way longer.

Blow It Dry, Dry, Dry

After (gently!) towel-drying your hair, apply Effortless Anti-Frizz Hair Spray for curly hair, and blow-dry the hair until it’s around 80% dry. For the final drying step, use your preferred brush to smooth and style the hair until it’s completely dry. Removing as much moisture as possible in the drying process will minimise the time you need to spend with hair straighteners, helping to minimise hair damage and breakage.

Don’t Skip The Straighteners

By now your hair will be looking enviably smooth and glossy, but we’re not done yet. Using hair straighteners further helps to seal and smooth the hair shaft, especially when used on top of a heat protecting, anti-frizz product like Elixir and 10-in-1 Leave-In Hair Treatment. We find that working in smaller sections enables us to catch every hair with the straighteners, and creates lots of movement in the hair for a more natural look.

Do Make The Smooth Look Last

To keep your hair straight all day, apply a finishing product, like a lightweight oil. With nourishing hair oils, a little goes a long way, so rub just one drop of Elixir between your palms and smooth over the hair lengths, focusing on drier areas, split ends and any sections that get frizzy. If you’re going to be out for the long haul, pop some hair oil in your bag for hair-smoothing touch-ups on the go.
