March in Australia is known for unpredictable weather, bringing increased humidity that can wreak havoc on your hair. If you have ever stepped outside only to have your sleek, polished hair turn into an unruly, frizzy mess within minutes, you are not alone. Humidity interacts with your hair’s natural structure, causing the cuticle to swell and making strands more prone to frizz, flyaways, and loss of shape.
At Hair Folli, we know how frustrating humidity-induced frizz can be. That’s why we’ve put together the ultimate guide on how to maintain sleek hair in humidity with lightweight, humidity-proof products. Whether you have straight, wavy, or curly hair, the right approach and products will help you keep your hair looking smooth, manageable, and frizz-free throughout the season.
How Humidity Affects Hair and Why It’s Worse in March
March in Australia marks the transition from summer to autumn, often bringing high humidity levels, especially in coastal areas like Sydney, Brisbane, and Perth. The excess moisture in the air disrupts the hair’s natural moisture balance, leading to puffiness, frizz, and unwanted volume.
For those with high-porosity hair or chemically treated strands, humidity causes even more noticeable changes. The more porous your hair, the more moisture it absorbs, making sleek styling even harder to maintain. This is why using anti-frizz hair products for humid weather is essential for keeping hair sleek and smooth.
As you prepare for the change in seasons, it’s equally important to prevent autumn dryness. Maintaining your hair’s hydration levels while protecting it from both humidity and the coming cooler, drier months will ensure that your hair stays healthy, nourished, and manageable throughout autumn.

Best Lightweight Hair Products for Humidity Control
1. Anti-Frizz Serums for Long-Lasting Smoothness
A good anti-frizz serum is one of the best lightweight hair products for humidity, creating a barrier between your hair and the moisture in the air. A lightweight, non-greasy formula works best for Australian weather, providing frizz control without weighing hair down.
Hair Folli’s anti-frizz serum is designed specifically to protect against Australia’s humidity, sealing the hair cuticle and keeping strands sleek for longer. Infused with hydrating and smoothing ingredients, it controls frizz while maintaining a soft, natural finish.

2. Leave-In Conditioners to Protect Against Humidity
A high-quality leave-in conditioner provides a layer of hydration and protection, keeping your hair smooth and manageable. The best leave-in conditioners for humid weather contain coconut oil, shea butter, or glycerin to lock in moisture and prevent frizz from forming.
Using a lightweight leave-in conditioner before styling helps maintain sleekness, preventing hair from drawing excess moisture from the air. This is especially beneficial for those with dry or curly hair that tends to frizz more easily.
3. Heat Protectant Sprays to Lock in Sleekness
If you rely on heat styling tools like blow dryers or straighteners, a heat protectant spray is essential. Not only does it shield hair from heat damage, but it also creates an invisible shield against humidity.
For best results, apply a lightweight heat protectant before using any styling tools. Hair Folli’s heat defense spray helps lock in sleek styles while providing long-lasting humidity resistance.
Humidity-Proof Hair Styling Tips
1. Reduce Wash Frequency and Use Hydrating Products
Overwashing your hair can strip away natural oils, making it more prone to frizz. Instead, use a sulfate-free shampoo two to three times a week to cleanse hair without removing essential moisture.
For those who struggle with oily roots, a lightweight dry shampoo can help extend the time between washes without disrupting your sleek style.

2. Master the Right Blow-Drying Technique
The way you dry your hair significantly impacts how well it holds up in humid weather. Using a round brush and directing airflow downward while blow-drying helps smooth the cuticle, making hair more resistant to frizz.
Always finish with a blast of cool air to set the style, locking in sleekness and reducing the chances of hair swelling in humidity.
3. Choose Lightweight Styling Products
Heavy creams and gels can weigh hair down, making it more difficult to maintain volume and smoothness. Opt for lightweight mousses, styling sprays, or serums that provide humidity resistance without buildup.
Applying a lightweight styling cream to damp hair before drying can help create a sleek look while keeping frizz under control.
Best Hair Care for Autumn Dryness and Humidity
March’s weather is not just about humidity—it’s also the beginning of drier autumn air, which can lead to dehydration and brittle hair. Keeping hair hydrated is key to managing frizz and preventing seasonal dryness.
As you focus on maintaining your hair health during this transitional period, remember that achieving longer lashes naturally in 30 days also requires similar care and nourishment. Just like your hair, your lashes can benefit from hydration and the right products that promote growth and strength. Incorporating natural remedies and serums into your beauty routine can give you the fuller, healthier lashes you’ve been aiming for, along with keeping your hair smooth and hydrated throughout autumn.
To maintain hydration:
- Use a deep conditioning treatment once a week to nourish and strengthen strands.
- Apply a hydrating hair mask infused with aloe vera or argan oil to restore moisture levels.
- Drink plenty of water and incorporate omega-3-rich foods into your diet for healthier, shinier hair.
