Wavy curls can hold pretty well during rainy days, but the secret to keeping them looking great is in the preparation and aftercare. Since rain brings moisture to the hair, wavy curls will likely frizz out or be less shaped when wet. However, with the right steps, you can keep wavy curls looking great even in wet conditions.
First, products that seal the hair against moisture and humidity are quite necessary. Anti-frizz serums or leave-in conditioners with silicone in them often create a thin protective coating over the hair strands. Thus, the hair cannot soak up extra moisture, which otherwise wreaks havoc on the wave pattern by creating frizz.
For instance, before you step out into wet weather, consider carrying a scarf or a hood to cover your curly hair when it rains. Although the braids may most probably get wet because of moisture in the air, minimizing direct contact with water will allow you to keep them on for a much longer period.
Allow your wavy bundles to dry air without rubbing or using a hot tool right away because it will damage them unnecessarily, and once dry, gently comb or finger detangle to regain their waveform.
Wavy bundles, especially high-quality human hair ones, prove to be very resilient and can come back from the wet weather if taken care of. That is all. Just remember, with the right moisture control, extra care during rainy days will keep your wave's integrity nice and frizz-free.
