Summer Hair Solutions for Frizz, Humidity and Heat Styled Hair
Summer: the season of flip flops, salty air and…frizzy hair.
It starts the moment you step outside. Your hard earned blowout collapses, the crown gets fuzzy and the ends puff up. Suddenly, your hair has a personality of its own.
The solution isn't smoothing things over after the puffiness appears. The best defense against frizz starts in the shower and continues through your pre-styling routine, helping protect your hair before humidity has the chance to take over.
Why Frizz Gets Worse in the Summer
Humidity is the ultimate summer hair sabotager. When moisture in the air penetrates the hair cuticle, it swells, cracks and lifts, turning smooth hair into a frizzy, fluffy, unpredictable mess.
But humidity isn’t the only culprit. Chlorine and salt water can strip hair of its natural protective oils, leaving it dry, brittle and prone to breakage, resulting in hair that's even more susceptible to frizz.
That doesn’t mean you need to skip the pool or beach this summer. You just need the right routine to help keep frizz from spoiling the day.
The Big Mistake: Only Treating Frizz After It Shows Up
Most people reach for glossing oils and anti-frizz creams after humidity has already done its damage. While these products can help temporarily smooth things over, they’re really just a quick fix.
As soon as hair looks frizzy, it means the cuticle has already been disrupted. At that point, most creams and oils can only coat the surface—they can't smooth the cuticle back into place. And while they may temporarily tame flyaways, they don't address the underlying cause and can often leave hair looking greasy or weighed down.
The smarter strategy is building a routine that smooths, strengthens and protects hair before frizz ever has a chance to take hold. Enter NULASTIN's three-step anti-frizz routine—the ritual we rely on to keep hair sleek, smooth and humidity resistant through even the stickiest days of summer.
Your Summer Frizz Control Should Start in the Shower
Step #1: Cleanse, Nourish, Fortify and Smooth with Vibrant Scalp Shampoo + Conditioner
This next generation shampoo and conditioner duo goes beyond surface level cleansing and conditioning. Formulated with NULASTIN’s Damage Defense Complex—a blend of hair bonding proteins and provitamin B5—it helps smooth the cuticle, reduce frizz and prevent breakage while boosting resilience for hair that's soft, smooth and full of shine.
In clinical testing, it reduced breakage by 56%, improved smoothness by 90% and increased shine by 95% after just one use.* Better yet, both formulas are powered by patented Elastaplex® Technology to help reduce visible shedding and support the look of fuller, healthier looking hair over time.
Use Vibrant Scalp Shampoo + Conditioner every time you wash your hair, whether that's daily or a few times a week.

Step #2: Reset 1x a Week With Vibrant Scalp Mask
Vibrant Scalp Mask is NULASTIN's bestselling hair mask for frizz and your weekly reset for summer stressed hair. Whether you've spent the day at the beach, by the pool or in the sun, this treatment helps replenish moisture, smooth the cuticle and restore softness to dry, frizz prone hair.
Inspired by the elastogenic benefits of red light, it transforms the look and feel of hair after just one wash, leaving it noticeably softer, smoother and silkier. Beyond instantly improving the hair itself, this triple-action treatment also helps calm and balance the scalp while supporting elastin at the root for healthier, stronger looking hair over time.
In clinical testing, 100% of users experienced an immediate improvement in softness, smoothness and shine.*
Use it 1–2 times per week in place of Vibrant Scalp Conditioner, or whenever hair feels extra dry, dull, rough or frizzy. Apply from root to tip, then let it work its magic for 5–7 minutes before rinsing.

How to Reduce Frizz in Summer: Bonus Tips
After Swimming, Always Rinse
Salt water and chlorine can leave hair dry, rough and more prone to frizz. A quick rinse after the beach or pool helps remove residue that can strip moisture from hair and contribute to frizz.
Don’t Skip Conditioner
Conditioning helps improve softness, smoothness and manageability—it’s a non-negotiable during the dry, scorching summer months.
Use a Mask After Sun Soaked Days
Keep Vibrant Scalp Mask in your shower as your once weekly reset step, especially after days spent at the beach or pool.
Avoid Over Washing
Washing too often can leave hair feeling dry and brittle, especially in the summer. When you do wash, make sure you opt for a frizz fighting shampoo + conditioner, like the Vibrant Scalp Shampoo + Conditioner Duo.
Air Dry When Possible
Blow dryers can damage hair and swell the shaft. When possible, try to air dry your hair. And if you must use a blow dryer, always make sure you’re protecting your hair—NuProtect™ helps shield hair from heat up to 450°F/ 232°C.
Get Ready for Your Smoothest Summer Yet
Summer humidity might be inevitable, but the frizz that often comes with it doesn’t have to be. With the right routine, you can help fight frizz and flyaways before they even take shape.
Vibrant Scalp Shampoo + Conditioner, Vibrant Scalp Mask and NuProtect™ Leave-In Primer are the essentials your hair needs to look its best all season long. Together, they help hair look softer, smoother, shinier and frizz free, even through the dog days of summer.
With consistent use, your hair won’t just resist frizz—it will look stronger, healthier and softer from root to tip. Because unruly summer hair deserves more than just a quick fix: it needs real, science backed solutions that deliver lasting results.
