Jaclyn LaBadia, Davines Writer

If you’re prone to frizzy hair, you know lots of things can bring it on, but nothing quite as much and as fast as humidity. Even the sleekest of strands are no match against frizz at the first sign of humidity. But there are steps you can take to humidity-proof your hair and win the fight against frizz. We’ll tell you how to protect hair from humidity with just a few simple tips and dream products.

Key Takeaways

How to Protect Hair From Humidity

Humidity breaks hydrogen bonds in hair, altering its texture and causing frizz — especially in porous or dry strands.
Curly and dry hair are more prone to frizz, while straight or fine hair can become limp in humid conditions.
Start with the right shampoo & conditioner, ideally anti-frizz or smoothing formulas that prime your strands against moisture.
Handle wet hair gently — use a microfiber towel and seal in moisture with a leave-in conditioner.
Apply anti-humidity styling products, like serums, oils, or gels, when hair is wet to lock out excess moisture.
Customize your approach for your hair type: curly hair benefits from protective styles and oils; straightened hair needs lightweight serums and gels.
Davines’ products like LOVE Smoothing Shampoo, OI All In One Milk, and OI Hair Butter help fight frizz while nourishing and protecting your hair.
Consistent moisture, minimal heat styling, and protective products are key to smooth, sleek, frizz-free hair even in high humidity

Why Hair Gets Frizzy in Humidity and How It Affects Different Hair Types

Humidity affects hair by altering the bonds in the hair shaft, changing the texture. Hair is made of two types of bonds, disulfide and hydrogen. Disulfide bonds are the stronger of the two, and determine the hair’s texture. Hydrogen bonds are weaker and easily broken and reformed by water. Hair is naturally porous, meaning it absorbs water easily. So in humid conditions, as hair absorbs the moisture from the air, the hydrogen bonds break and reform, leading to a change in the hair's texture.

Curly hair is naturally more porous and tends to frizz more readily than straight. In fact, thin or straight hair tends to react to the added weight of absorbed moisture by becoming limp and lifeless.

Your hair’s hydration level also plays a part in how it will react. The drier the strands, the more porous they are and the more moisture they’ll absorb, leading to a higher chance of frizz.

Steps to Protecting Your Hair From Humidity

The good news is that preventing frizzy hair in humidity is possible. Wondering how to protect hair from humidity naturally? Let’s take a closer look at some anti-humidity hair tips.

Shampoo and Conditioner for Humidity Protection

The main goal of anti-frizz products is smoothing the cuticle and creating a barrier against humidity. So more than just cleansing and conditioning your hair, anti-frizz shampoos and conditioners act as a primer for frizz-free styling.

Towel-Drying Habits and Moisture Management

Next up in your defense against humidity is the way you towel-dry. Gently squeeze the moisture from your strands with a microfiber towel to minimize roughing up cuticles and exacerbating frizz by rubbing. Apply a leave-in conditioner as your final step to seal in moisture as your hair dries.

Using Styling Products Effectively

Your styling products also play a role in humidity-proofing your hair. The best anti-frizz formulas come as serums, oils and gels to seal and block outside moisture. Apply them to your hair when it’s soaking wet for better absorption into the hair.

Protecting Your Hair from Humidity

Humidity impacts each hair type differently, so your protection strategy should be tailored to curly or straightened hair. Wondering how to protect curly hair from humidity? By preventing moisture from the air from disrupting the hair's structure, with oil-based anti-frizz products and protective styles. And how to protect straightened hair from humidity? In much the same way—by focusing on moisture control and creating a barrier against the environment with products like serums and gels.
