Did you know that for curly hair types, humidity can increase frizz by over 80%? If your curls have ever turned into a poofy cloud after you step outside, you are not alone. In the US, the summer season means dealing with blaring heaters and sky-high humidity levels which can be especially annoying for people with curly hair.
In this guide, you’ll learn how to maintain curls in humid conditions when summer comes rolling around in 2025. From explaining the scientific reasoning of why curls react to humidity and moisture in the air, to practical recommendations on steps and products, we’ll go over everything. Loose waves or tight coils, this piece caters to all.
Who Should Read This?
This guide is a one stop shop for people with coily, curly or wavy strands who are fed up with battling frizz in the summer heat. It’s also handy for hairstylists hoping to provide some guidance to their clients on seasonal maintenance.
Why is Humidity a Challenge for Curly Hair?
The higher the humidity level, the more water particles there are in the air. Naturally, when compared to straight hair, curly hair is more porous which means it has a higher volume. As these water particles enter the hair, shafts become filled and the strands begin to unevenly swell leading to disruption in curls and subsequently, frizz.
- Curly hair features wavy strands and irregular cuticle layers.
- Higher moisture penetration equals high porosity.
- Hydration changes the curl pattern by breaking the hydrogen bonds in the hair.
Have you ever noticed how your curls become poofier, less defined, and more unmanageable while outside within ten minutes? Yep, that’s an effect of humidity.
Step by Step – A Humidity Friendly Routine for Curly Hair
This is your routine to keep curls hydrated, defined, and frizz-free regardless of how humid it gets.
Step 1: Gentle Cleansing – No Sulfates
