Anti-Frizz Sprays That Fit in Your Purse and Save Your Hairstyle

On rainy days it’s almost impossible to have the perfect hairstyle. Humidity increases, and this causes the hair to lose its shape, small rebellious flyaways appear around the face and the ends begin to frizz. A situation especially common during autumn, when the weather can change from one moment to the next.

Although we usually pay close attention to the products we use before blow-drying, there is a gesture that can make a difference when we’re already out: carrying an anti-frizz spray in the bag. We’re not talking about the classic treatments that require applying heat, but light formulas that are used on dry hair to keep the hairstyle under control.

Why hair frizzes more when it rains

The frizz doesn’t appear only because the hair gets wet. Ambient humidity can temporarily modify its shape as well. This happens because the water present in the air interacts with the hair fiber and alters the hydrogen bonds that help maintain the hairstyle.

When this occurs, straight manes can begin to wave, the ends lose definition and those little hairs that seem to have a life of their own appear. The phenomenon tends to be especially visible on porous, dry or damaged hair, although it can affect any hair type.

Humidity-reducing sprays are formulated to help reduce this problem. Depending on the product, they may contain polymers that form a protective film over the hair, conditioning ingredients that impart softness or fixing agents that prolong the duration of the hairstyle.

Therefore, a spray can help prevent frizz and control rebellious strands, but it will not completely restore a straightened look that has already been damaged by the rain.

The luxury brand Oribe has one of the most interesting products for those looking to protect their hairstyle from humidity without sacrificing the natural movement of the hair.

Its Imperméable Anti-Humidity Spray is designed to create a protective barrier that helps keep frizz at bay. It can be used on both straightened manes and on wavy and curly hair. In addition to fighting humidity, it provides a light hold that allows the hairstyle to maintain its shape without hardening.

How to use an anti-frizz spray without weighing down the hair

Although these products are designed to facilitate styling, using them correctly is important to achieve a natural finish. In general, it is best to start with a small amount and add more only when necessary.

It is also useful to distinguish between sprays that provide softness and those that set the hair. The former can be especially helpful when the ends start to look dry or frizzy, while the latter work better for controlling the fringe, loose strands and maintaining the hairstyle’s shape.
