Rocío Barrio, curl expert: "Putting oil in your hair will prevent humidity from causing frizz, because oil and water repel each other."

Posted on 31 October 2026

Curls and humidity don't usually get along too well. That's why, with the arrival of the rainy season, frizz increases 1000%, causing the curls to lose their definition and the volume that works so hard to achieve to fall. But there is a trick to avoid it, which the hair expert curly Rocío Barrio uses it to show off her great hair even on the most humid days.

Its secret is Kiaora oil, a silicone-free hair treatment that mixes vegetable oils of jojoba, argan, marula, olive, broccoli and camellia. This product is specially formulated to soften curly hair and make it easier to detangle without breaking it. In addition, it helps control frizz and provides a very natural shine that adds definition.

“Oil and water repel each other. Therefore, putting oil in your hair will prevent humidity from causing frizz. It was that simple.”

The curl expert pours a few drops into her hand and emulsifies the oil, rubbing it with her palms. Next, distribute it throughout your hair, starting at the ends and rising little by little, reaching the middle and even the top of the head. Yes, you pour oil on the roots, because that is where there is more baby hair and where the most frizz accumulates.

Next, set the curls as usual. First use leave-in throughout the hair and spread it thoroughly, brushing so that the product adheres well to the hair. Then, complete the sealing process with the gel, doing scrunch and leaving five minutes for it to absorb, before drying your curls with a diffuser.
