How to Stop Frizzy Hair in Humidity: 7 Hot-Weather Tips (Product Review)

Welcome to my 7 tips to stop frizzy hair in hot weather product review! If you’re a curly girl like me-or even if you just have a slight wave to your hair—you probably struggle with frizzy, unmanageable hair during those humid months. I know I do! That’s why I was so excited to try the Nutree Brazilian Keratin Hair Straightener. And let’s just say, this product has completely surpassed my expectations! And not just that. The reviews are DYNOMITE!!! Woman love this product.

Below you will see my before and after pictures and the whole process.

As we address overcoming frizzy hair in hot weather. I will throw in a few product recommendations that are good stand alone alternatives to the Keratin Hair Straightener that I am using. This product is one of my favorites as a companion to any hair care routine. It is a luxurious satin pillow case for hair and skin.

So let ‘s jump into my the review!

This is my before hair treatment pictures. See my after shot below.

I recently purchased Nutree Brazilian Keratin Hair Straightener and put it to the ultimate test: the last three days have been nothing but high humidity and lots of rain. Normally, that’s a recipe for disaster for my hair. But after using the Nutree keratin treatment, my hair stayed styled the entire time.

No joke, I even went out Latin dancing (which, if you know, means a lot of sweating and movement), and my hair held up beautifully. Usually, by the end of a night like that, my hair would turn into a frizzy, sweaty mess. This time, my hair was still smooth, defined, and frizz-free. I honestly couldn’t believe it!

 

Unboxing the Product

Before I even started, I took a picture of the Nutree Brazilian Keratin Hair Straightener right out of the box. The packaging was sleek, and everything was neatly organized inside. I appreciated how each bottle was clearly labeled, making it super easy to follow the instructions.

The treatment itself was super easy to do on my own. It took me about an hour and a half from start to finish, and the instructions were straightforward. I really appreciated that I didn’t need any fancy tools or extra hands. I just followed the steps and let the product do its magic. My hair feels incredibly silky now, dries so much faster, and is way easier to manage. The best part? I still have my curls! They’re just a lot more defined and totally free of frizz, even in the worst humidity.

 

Step 1: My Hair Before the Treatment

Here’s a look at my hair before I began. Though I’m naturally curly, I tend to wear my hair straightened for convenience.  You can see the frizz that comes with living in a humid climate, especially since it had been raining for about three days at this point. This is what I was hoping the treatment would help me manage.

 

 

Step 2: Applying the Treatment

The application process took me about an hour and a half from start to finish, and I was able to do it all by myself. The instructions were very clear, and I didn’t need any fancy tools—just sectioning my hair and working the product in. I snapped a photo of my hair after the I applied to treatment into my hair.

 

I should mention, I’m not a stranger to Nutree products. I’ve used their hair botox in the past and absolutely loved the results, but the fumes from that treatment would burn my eyes and make it hard to keep using. I was really hoping the keratin treatment would be gentler, and it was. There were no fumes at all! It made the whole process so much more comfortable, and I didn’t have to worry about any irritation.

Step 3: Waiting and Rinsing

After letting the treatment sit, I rinsed and styled as directed. I was relieved that there were no fumes at all with this keratin treatment, unlike Nutree’s hair botox, which I’ve used before but found tough on my eyes due to the fumes. This time, the process was completely comfortable.

All in all, I’m honestly blown away by how well the Nutree Brazilian Keratin Hair Straightener worked for me. It’s definitely something I’ll continue to use, especially now that I know my hair can survive even the muggiest, rainiest days (and the dance floor!). If you’re looking for a way to keep your curls or waves frizz-free and manageable, I can’t recommend this enough

The Final Result

Now for the best part: the results! My hair felt silky, dried faster, and was so much easier to manage. My curls were still there, just much more defined and—best of all—completely frizz-free when straightened, even after three days of high humidity and rain. I even went Latin dancing, and my hair held its style the entire time, which never happens for me.

What Causes Frizzy Hair in Hot Weather?

I used to think frizz was just my hair “acting up,” but once I got a sense of the science behind it, fighting it got way easier. Frizz mostly happens because your hair tries to soak up moisture from the air, especially when it’s hot or humid. When the cuticle (the outer layer of your hair) lifts, moisture rushes in and your strands expand in all directions.

Let’s break down what’s actually going on:

• Lack of Moisture: Hair that’s dry or damaged will try to grab any bit of water from the atmosphere, which leads to swelling and frizz.
• Humidity: Hot air holds more moisture. When that moisture gets into your hair shaft, your smooth style puffs up and loses shape fast.
• Heat Damage: Frequent heat styling opens up the hair cuticle, making it easier for swelling and frizz to happen.
• Porosity: If you have high porosity hair (common with curly or color-treated hair), your strands let in a lot more moisture from the air. This can be a big cause of frizz for many people.

Basically, your hair wants balance: not too dry, not overloaded with moisture from the air. Keeping the cuticle sealed and hydrated is the secret to stopping frizz before it starts.

Quick Overview: Ingredients That Really Help in Hot Weather

I’ve looked over ingredient labels for years, aiming to spot things that actually do what they say. The right ingredients can mean the difference between a smooth hair day and a frizzy mess. Here are ones that work best for me in high heat and humidity:

• Silicones (like dimethicone, cyclopentasiloxane): They form a barrier around each strand, keeping humidity out. They get a bad rap sometimes, but for summer emergencies, they’re very helpful (especially in serums and leave-ins).
• Glycerin (in the right formula): Draws moisture into the hair, but be careful—if there’s a lot of moisture in the air, glycerin can make things worse. It works best balanced with oils or used in moderate humidity.
• Coconut Oil and Argan Oil: Light oils that both seal the hair cuticle and add shine. These are my go-to when I want something natural and lightweight.
• Shea Butter: Rich, but not too heavy, this is perfect for thick or curly hair and coats strands so fewer flyaways appear.
• Aloe Vera: Adds slip to curls and waves, moisturizes, and helps smooth down roughness, all while feeling fresh on hot days.
• Hydrolyzed Proteins: Like keratin or silk protein. They fill in tiny cracks along the hair shaft, making hair less likely to frizz up.
• Panthenol (Pro-Vitamin B5): Holds moisture to the hair without weighing it down and boosts shine.

These have always given me more predictable hair days in summer. Plenty of products blend a few of these to get reliable effects.

7 Tips to Stop Frizzy Hair in Hot Weather

You don’t need a wild routine—just a handful of tactics that actually work when it’s hot, sticky, or dry. Here’s what I’ve learned for keeping your style looking great no matter the weather.

1. Lock In Moisture Early (Never Skip Leave-In Conditioning)

A big game changer for me was applying my anti-frizz leave-in cream or spray before stepping outside on a hot day. This is about “priming” your hair, like with makeup. Moisturizing needs to happen when your hair is still damp, not after it starts puffing up.

• After washing, gently blot excess water and use a wide-tooth comb.
• Apply a frizz-specific leave-in conditioner. Go for a formula with something like argan oil, panthenol, or keratin.
• Avoid heavy butters if your hair is fine; choose light sprays if your hair is thin, and creams if your hair is thick or curly.

I always notice with this step, my hair holds its shape and definition throughout the day, no matter how hot it is outside.

2. Smooth Cuticles With a Blast of Cold Water

This tip sounds odd, but rinsing out conditioner with cool (not icy) water is magical. The cold closes those tiny cuticle scales, helping keep in moisture and blocking muggy air.

• You don’t need to stand under a freezing shower. Just switch to cool water for the last 10-20 seconds of your rinse.
• Air dry or use a microfibre towel; avoid rubbing, which adds frizz.

The difference with a cool rinse is especially noticeable if you’ve got wavy or curly hair that likes to poof up right after washing. Using a satin scarf or pillowcase at night enhances this effect too.

3. Style When Hair Is Damp, Not Wet or Dry

Applying serums as soon as you get out of the shower works best when your hair is damp, not dripping. If it’s too wet, products slide off. If it’s dry, the cuticle is already starting to lift.

• Gently squeeze your hair with a towel (don’t wring it).
• Apply styling creams, serums, or mousse now.
• This seals in moisture and keeps your style smooth for longer.

This step is massive if you’re using curl creams or wave enhancers. It’s ideal for preventing root frizz too.

4. Use Anti-Frizz Serums or Oils as a Final Step

My favorite frizz stopper is a lightweight serum with silicones plus a touch of argan or coconut oil. The key is using only a pea-sized drop; too much will weigh hair down, especially if it’s fine.

• Rub the product between your palms and lightly press over the surface of dry hair, focusing on the ends and any flyaways.
• This instantly smooths the outer layer and adds gloss without causing greasiness.

On humid days, I sometimes add a tiny extra bit before walking outside. This final shield makes a real difference throughout the day.

5. Avoid Hot Styling Tools Whenever Possible

Flat irons, curling irons, and blow dryers at high temps can open the hair cuticle, making it likely to soak in outside moisture. In summer, I lean into airdrying or low-heat styling as much as I can.

• If you must blow dry, always use the cool setting and a diffuser.
• For curly hair, try the “plopping” method with a T-shirt or microfibre towel to help curls dry more defined and less frizzy.
• For straight or wavy hair, braid your hair or put it in a loose bun for heatless styling overnight.

Skipping hot tools made my hair shinier and less dry, and frizz became less of an issue.

6. Use Sulfatefree Shampoos to Avoid Sudsy Stripping

This was an eye opener for me. Classic shampoos with sulfates can strip away natural oils, making your hair crave moisture the minute you leave the house. Sulfatefree cleansers are much softer, so you start off less frizzy from the shower itself.

• Look for labels with “sulfatefree” and “moisturizing.”
• Ingredients like aloe vera, coconut oil, and panthenol in these formulas help a lot too.

After switching to gentle cleansers, I deal with much less “halo frizz” and can stretch out the time between washes without looking frazzled.

7. Protect Hair Overnight With Satin or Silk

Nighttime routines matter as much as morning ones. Cotton pillowcases can tug on your hair, leading to breakage and more frizz while you sleep. I can honestly say switching to a satin or silk pillowcase transformed my morning hair game.

• If possible, swap your standard pillowcase for satin or silk to lower friction and make your style last longer overnight.
• For curly or textured hair, wrapping your hair with a satin scrunchie or scarf keeps curls intact.
• Braiding your hair or using a loose topknot also makes a big difference, especially for waves and curls.

Now I wake up with far fewer tangles and almost never have to fight my brush in the morning!

Product Ingredients That Help Manage Hair in Heat

Certain ingredients shine during summer months. Here are my go-tos and what they really do on those hot, sticky days:

• Hydrolyzed Silk or Wheat Protein: Adds strength and plugs up weak spots in your hair shaft; especially useful for color-treated or brittle hair.
• Argan Oil: Lightweight but deeply nourishing, excellent for all hair types (from fine to coily).
• Dimethicone or Cyclopentasiloxane: Silicones. They don’t “fix” hair, but they are highly effective at fending off humidity for the day.
• Shea Butter: Ideal for thick or textured hair. It holds hydration and blocks humidity from getting in.
• Panthenol: Also known as provitamin B5, locks in moisture and keeps hair soft and flexible.
• Rice Water Extract: Full of amino acids that help smooth and repair the cuticle.
• Jojoba Oil: Mimics natural scalp oil, helping balance moisture in straight hair as well.

Scan your product’s ingredient list for these and you’ll likely spot your hair handling the heat a lot more predictably.

Product Suggestions to Manage Hair and Keep It Curly (or Smooth)

Here are my favorite picks for building a frizzfighting routine, tested on my own hair and recommended for a range of textures and budgets:

• FrizzEase Extra Strength Serum: A classic! Use on damp hair, then on dry ends. Works for straight, wavy, or relaxed hair, especially in high humidity.
• SheaMoisture Coconut & Hibiscus Curl Enhancing Smoothie: Creamy but never greasy. Great for thick curls and coils—keeps curls shiny, bouncy, and flexible, and frizz doesn’t get a chance.
• Ouai LeaveIn Conditioner: Lightweight spray packed with tamarind seed and panthenol. Fantastic for fine to medium hair that needs moisture but hates grease.
• Briogeo Farewell Frizz Rosarco Milk LeaveIn: Mixes rosehip, argan, and coconut oils without ever feeling oily. Super for daily frizz control, especially if you have waves or loose curls.
• Maui Moisture Smooth & Repair + Vanilla Bean Shampoo: Sulfatefree and seriously moisturizing. Handles frizz and breakage, giving softness without droopiness.
• Moroccanoil Treatment Light: For fine but frizzy hair, this light oil adds shine, controls frizz, but never makes things limp.
• Pattern Beauty Hydration Shampoo: Designed for curls and coils, but gentle enough for wavy, frizzprone hair in dry heat as well.

Other tools worth adding to your arsenal:

• Satin pillowcases or wraps (goodbye, nighttime tangles)
• Microfibre or T-shirt towels for gentle drying
• Wide-tooth combs for detangling without snapping hair
• Diffuser attachments for scrunching in product and controlling airflow

Everyone’s hair is unique, so some trial and error pays off. I’ve found that sticking to one or two core products, instead of constantly switching things up, helps my hair “settle down” and look its best.

Core Training: The Right Routine Order for Long-Lasting Results

I didn’t realize for a long time that the order in which you use products and steps makes a big difference. Here’s the routine I follow every summer for smoother hair, which is especially helpful for curls or waves:

• Sulfatefree wash every 2-4 days (avoid overwashing, which just dries out your scalp).
• Rich conditioner, focusing on the mids and ends—detangle first with fingers, then with a wide-tooth comb.
• Final rinse with cool water to close cuticles.
• Gently blot dry (skip the rough towel drying!)
• Apply leave-in conditioner while hair is still damp.
• After styling, a small layer of lightweight oil or serum seals in your work.

On extra humid days, bringing a travel-sized serum for quick touch-ups will save your style by evening.

Expert Classes: What the Pros Say About Summer Frizz

Hair professionals I’ve followed and watched all echo a few themes for summer frizz:

• Moisture balance is key: Too much moisture with no sealant causes limp, undefined hair.
• Less is more: Piling on products creates buildup and more frizz. Stick with fewer essentials.
• Sealing matters: Oils or silicones after your leave-in product help trap the good stuff inside and stop humidity from wrecking your style.
• After swimming or sweating a lot, a gentle rinse plus a dab of leave-in keeps your hair from drying out or swelling up later.

Every stylist I know says a smart anti-frizz routine becomes second nature. My hair is honestly less “stressed” simply because it knows when and how it’s being cared for!

Market Research: How to Find Expert Anti-Frizz Advice for Your Hair Type

If you want to take things up a notch, researching advice for your particular hair texture saves time and money. Here’s how I track down the best info and recommendations:

• Read reviews from folks with hair like yours (and take climate into account—what works in Miami may flop in Phoenix).
• Follow curly hair, wavy hair, or anti-frizz tags on Instagram or TikTok to see real-life routines and results.
• Check ingredient lists, and avoid products with drying alcohols or harsh detergents.
• Don’t overlook drugstore brands—some of my winner frizz-fighters are under $15.

Every time I’ve done a bit of research, I’ve found great results faster and with less frustration.

You Can Style Your Hair as You Like, Even When It’s Hot

Back in the day, I’d give up and pull my hair back any time it got warm, but heat and humidity don’t have to control your look. With a few tweaks, you can stick to your personal style goals, like:

• Longer-lasting blowouts, even in muggy air
• Curls and waves that stay defined instead of ballooning out midday
• Braids, ponytails, and updos that look polished, not frazzled
• Sleek styles that don’t need endless hairspray (really, too much can trigger more frizz!)

I love letting my natural texture show, but everyone deserves options. With these summerproof tweaks, you can shake things up and wear your hair however you want—without a “frizz explosion” by lunchtime.

The Anti-Frizz Community: Forums and Groups That Share the Best Tricks

I’ve learned so much from online communities full of real people with tricky hair. Forums and Facebook groups are loaded with step by step routines, before-and-after pictures, and product suggestions for all hair types in all climates.

• /r/CurlyHair and /r/FancyFollicles on Reddit for those with curly, wavy, and straight hair fighting the heat
• Facebook “curly hair” and “humidity hair help” groups for swapping products and advice
• Haircare Discord rooms, where people share daily wins and fails

If you ever feel stuck or like your hair is just impossible, these groups are encouraging and overflowing with smart, practical tips (not just “rub on coconut oil” over and over!).

High Performance Accessories That Keep Frizz Down

Adding just a couple of the right accessories can really give a boost to your summer hair routine. I recommend:

• Microfibre Towel: Gentler than a regular towel and soaks up water fast without wrecking your strands
• Satin/Silk Bonnet: It might feel a bit retro, but it’s totally worth it for next-morning hair that’s easy to style
• Diffuser Attachment: For curly and wavy hair, keeps definition looking great and frizz under control (especially used on low, cool air)

These tools help your daily routine work even better and can be complete game changers in muggy weather.

How to Maintain Good Hair in Heat: Day-to-Day Tips

There’s no magic permanent cure for frizz, but a few daily habits make it much more manageable:

• Spritz your hair with a little water and smooth flyaways with a small dab of leave-in or oil during the day
• Shield your hair from direct sunlight (toss it up or cover with a loose hat)
• Avoid brushing dry hair too much—fingers or a wide-tooth comb do the trick
• If hair is starting to puff up, a bit of water on your hands and a dab of serum is an instant rescue

Having a travel-sized leave-in or serum in your bag can be a complete day saver.

Pricing: What You Actually Need to Spend on Anti-Frizz

Not all fantastic products cost a fortune. Many hyped serums didn’t work better for me than cheap drugstore brands. Here’s how to budget for anti-frizz needs:

• Under $10: FrizzEase Serum, OGX or Maui Moisture shampoos, Garnier Sleek & Shine Leave-In
• $10-$25: SheaMoisture, Cantu, Ouai leave-ins, Moroccanoil Treatment Light (trial size)
• $25-$40: Briogeo Farewell Frizz, Living Proof No Frizz, Pattern shampoo and conditioner

Accessories like microfibre towels, satin pillowcases, or bonnets usually last months, if not years—a small upfront cost can make your routine work better long-term.

My Final Thoughts

This review was a lot of fun. Fighting the heat and staying cute is a never ending challenge. We keep getting smarter at winning the game :).

I’ve endured lots of frizz and my fair share of frustration, but with the right mix of products, habits, and tools, even the hottest, stickiest summer weather hardly scares my hair anymore. Most fixes are quick to try, and a little bit of experimenting can pay off big. Sometimes, it just takes one swap—maybe a better leave-in, a smarter towel, or switching to cool rinses—to see a real difference.

Every head of hair is different, so check in with yourself and tweak the routine until it just feels right. Smooth, soft, shiny hair in the summer is possible, and these tips can help you get there. No more hiding from humidity or missing out because of wild hair days!
