How to prevent frizz this summer

When we think about our hair during summer, we usually focus on the sun, chlorine or seawater. However, there’s another factor that has a huge impact on the appearance of our hair and often goes unnoticed: humidity. During this time of year, we spend more time at the beach, by the pool or travelling to destinations with higher levels of humidity. And that’s exactly when one of the most common hair concerns appears: frizz.

Why does hair get frizzier in summer?

The hair fibre absorbs moisture from the surrounding environment. When this happens, the cuticle becomes disrupted, causing the hair to lose definition and control. The result? Frizzy hair that is harder to manage and style, with a less polished finish, even after spending time blow-drying and styling it. That’s why we always recommend incorporating an anti-frizz treatment into your haircare routine, especially during the summer months.

The importance of protective hair barriers

Just as we protect our skin, our hair also needs protection from external factors that can affect its appearance. Rain Coat was developed to create an invisible barrier around the hair fibre, helping to protect the hair from humidity and control frizz.

Its technology is activated by heat, whether through blow-drying with tension or by using thermal styling tools such as a flat iron. Once activated, the product helps seal the surface of the hair, making it more difficult for moisture to penetrate the fibre. The result is smoother, shinier, softer and frizz-free hair, even in humid environments.

The technology behind rain coat

Rain Coat uses thermo-active technology capable of forming an ultra-lightweight film over the surface of the hair. This protective barrier acts like a shield against humidity, helping to seal the hair cuticle and keep it smoother and more uniform for longer.

Additionally, Rain Coat does not alter the internal structure of the hair or change its natural texture. It is not a straightening treatment. It is applied to freshly washed, damp hair after a leave-in product and/or a heat protectant such as South Bondi. It does not change the shape of the hair. It simply creates temporary protection against humidity to help keep hair under control and free from frizz.

A completely washable protection

One of the things we love most about Rain Coat is that its effect is completely washable. The protective film remains on the surface of the hair and gradually disappears with each wash.

That’s why it has become one of our summer essentials. Because once you understand that summer frizz is not always caused by your hair itself, but often by the environment around it, the way you care for your hair changes completely.

Now you know our secret to achieving perfect hair during summer sunsets and idyllic holidays under the sun.

So, what are you waiting for? We simply can’t live without it.
