When summer hits, our minds are filled with sun-soaked beach days, rooftop happy hours, and breezy outfits. But there's one major beauty dilemma that threatens to deflate the fun – literally: flat, limp, lifeless hair.

Heat and humidity can wreak havoc on fine, thinning hair types in particular. Summer weather can be at odds with your goals of volume and thicker-looking hair.

The good news? With the right hair care routine and smart styling tips, you can get thicker-looking hair in the summer heat.

Let’s dive into the ultimate guide on how to achieve hair that looks thick and voluminous during summer. We’ll share expert tips, product recommendations, and foolproof hairstyles to help you shine through the season.

Understanding the Summer Hair Struggle: Why Hair Falls Flat

Summer brings sunshine and longer days – but also intense heat and heavy humidity. These environmental factors can affect your hair's behavior, especially if it’s already fine or thinning.

Heat and sweat increase oil production at the scalp, which can weigh hair down at the roots. Add humidity into the mix, and you’re left with frizz, limp roots, and a lack of structure. It’s enough to make boosting hair volume in hot weather seem like an uphill battle.

Here are a few ways summer conditions can affect your hair:

Humidity causes the hair shaft to swell, leading to puffiness without shape.
Sweat strips hair of its bounce and freshness.
UV exposure can dry out your strands, making them brittle over time.

All these factors combined can make your hair appear thinner, duller, and far from your ideal summer hair goals.

What Can You Do About It?

You may feel tempted to use oils, serums, or other heavy products to target flat roots and flyaways. But these products can weigh down hair, causing it to lose its natural movement and fullness. Even naturally thick hair can look lifeless if you don’t care for it properly in summer conditions.

That's why summer hair care for volume needs a special approach. It should focus on hydration without making hair heavy and lift without causing buildup.

A Summer Hair Care Routine for Volume

For thicker-looking hair in the summer, start in the shower. Your hair care routine should be lightweight, buildup-free, and designed to boost your hair's body from the root.

Lightweight Cleansing for Fine or Thin Hair
Prevent limp locks by using the right shampoo and conditioner. Choose a volumizing shampoo that cleanses the scalp thoroughly without stripping your hair. These shampoos remove sweat, oil, and residue – common culprits that flatten hair in the summer.

Avoid heavy conditioners that sit on the hair and weigh it down. Instead, choose hydrating yet lightweight conditioners for volume.

Product Recommendation: Try our RevitaLash® Cosmetics Thickening Shampoo and Thickening Conditioner duo. Our sulfate detergent-free formulas feature botanical ingredients and proteins to strengthen hair without heaviness.

Daily Treatment for Volume & Strength
Once a day, incorporate a volumizing treatment with benefits for your hair and scalp. Avoid heavy scalp serums, which can weigh down fine hair at the roots. Instead, look for a lightweight yet nutrient-rich formula that leaves hair feeling clean – while boosting its strength and body.

Product Recommendation: Our RevitaLash® Cosmetics Volume Enhancing Foam is a summer must-have for fine or thinning hair. This lightweight foam is physician-developed with our signature BioPeptin Complex®.

Our technology includes lipids, peptides, biotin, and panthenol. These ingredients help condition, strengthen, and soften hair. They also protect against breakage and brittleness.

Protection from Heat and Humidity
Before any heat styling, apply a heat protectant spray that also offers anti-humidity benefits. These products create a barrier that locks in moisture while preventing frizz and droop.

Pro Tip: Always apply heat protectant products from mid-lengths to ends to avoid overloading your roots.

Summer Styling Techniques for Volume

Styling plays a pivotal role in how to maintain hair thickness in summer heat. From heatless methods to blow-drying tricks, here’s how to keep your hair looking fuller and fresher longer.

Heatless Styling Hacks
On hot days, the last thing you want is more heat. These summer hair hacks for thicker-looking hair are effortless and effective:

Overnight braids or twists create beachy waves that enhance volume and texture.
A high bun or ponytail while hair is damp can give your roots a natural lift when let down.
Use a volumizing foam for summer hair before setting your hair in braids or buns to add body.

Blow-Drying for Maximum Volume
If you do use heat tools, make them work for you:

Blow-dry with a round brush, lifting hair at the roots.
Flip your head upside down while using a blow dryer to encourage lift and airflow at the roots.
Finish with a blast of cool air to set the style and lock in volume.

Pro Tip: Use a root-lifting spray or mousse before blow drying. These summer-friendly styling products expand the hair shaft and add volume.

Diet and Supplements for Healthy, Full Hair

Volume doesn’t just come from products – it starts from within. What you eat can have a significant impact on your hair’s appearance and vitality.

Nutrition for Healthy Hair

Biotin, omega-3 fatty acids, and protein are essential nutrients for hair health and strength.
Stay hydrated to support hair elasticity and shine.
Think about adding a daily supplement for hair health to your summer routine. This can help you achieve hair that looks full and thick in the summer heat.

Hairstyles for the Look of Volume and Thickness

Choosing the right style can make all the difference in how thick your hair appears. Here are a few heat-friendly hairstyles for volume that are perfect for summer:

The Classic Summer Blowout
A voluminous, bouncy blowout never goes out of style. Perfect for date nights, summer weddings, or just a confidence boost.

Messy Braids or Waves
Textured waves and messy braids give off a carefree summer vibe while naturally creating the illusion of thicker hair. Use a sea salt spray for added grit and grip.

High Ponytail or Topknot
Not only do they keep you cool, but high updos lift the roots and give the appearance of thicker, fuller hair.

Common Mistakes to Avoid

To truly achieve volume and the look of thickness for summer hair, steer clear of these common errors: Using too much product: Even lightweight formulas can backfire if you layer excessively. Less is more. Going too long between washes: Product buildup can suffocate your scalp and weigh down your roots. Use a shampoo with gentle scalp exfoliating ingredients (like willow bark) when your roots begin to feel oily. Over-styling with heat tools: Heat can lead to damaged hair with breakage and thinning. Always use heat protection and embrace no-heat styles when possible.

Conclusion: Voluminous Summer Hair Can Be Yours

Achieving your summer hair goals isn’t just a fantasy – it’s completely possible with the right care, tools, and habits. To get fuller-looking hair this summer, create your ideal summer hair routine.

Use lightweight hair products and try volume-boosting techniques. Nourish your hair from within. This way, you can achieve thick-looking, voluminous hair, even in humid weather.
