A humid climate can wreak havoc on the health of your hair. Humid weather causes your hair to soak up moisture, which makes your cuticle swell and lift, leading to frizz.
Instead of fighting your natural texture—be it wavy, curly, or coily—try using anti-humidity products to keep your strands defined and frizz-free.
1. Keep Your Hair Hydrated
Humidity can cause even the most meticulously styled hair to turn into frizz-inducing unruliness. That’s why it’s important to keep your hair hydrated. This can be done by using moisture-boosting hair products that are designed for your hair type, such as a sulfate-free shampoo and conditioner. Alternatively, you can try a serum that is designed to help combat frizz, such as a leave-in formula. Another option is to wear your hair up in an easy, humidity-resistant updo. This can prevent your strands from expanding a la Monica Geller on vacation in Friends, and it will also keep them out of your face and off of your neck.

Getting a professional keratin treatment can be a great way to keep your hair looking smooth and sleek all year round. However, there are some things you need to know before booking a keratin appointment. For one, you’ll need to wait a few days before washing your hair. This is because keratin treatments take time to seal in, and washing it too soon could disrupt the results.
Additionally, some keratin treatments contain formaldehyde, which has been linked to respiratory irritation and other health concerns. Thankfully, there are now several different options on the market that are both formaldehyde-free and safe to use. It’s important to ask your stylist what they recommend.
If you’re looking for a way to beat the humidity and keep your hair frizz-free, consider a keratin treatment. This mind-blowing hair treatment can give you smooth, frizz-free locks that last up to five months. With proper care and upkeep, you can extend the life of your keratin treatment for as long as possible. Just remember to avoid swimming in chlorinated or salty water, and use sulfate-free shampoo and conditioning products to upkeep your hair.
2. Don’t Overstyle
At MG Hair Studio in Coral Gables A keratin treatment is known for its ability to smooth unruly hair, making it easier to style and maintain sleek locks. While the in-salon process is a popular way to achieve a picture-perfect blowout, the treatments are not without their risks and are best done only two or three times per year. The process uses a solution that contains keratin, a protein naturally found in your hair. After it has been applied, the stylist will use a flat iron to seal the solution into your hair strands.
The keratin treatment locks in moisture, repairs hair damage and breakage, and helps to improve strength and elasticity, all of which can help reduce frizz in humidity. It also helps to speed up blow drying time and can boost shine for a gorgeous look that is both stylish and manageable.
Before booking a keratin treatment, it is important to understand your hair texture and health status. A professional stylist can help you choose a treatment that will align with your goals and not jeopardize the integrity of your hair. They can also recommend a pre-treatment routine that will prepare your hair for the treatment.
For instance, if you have fine or thin hair and want a volumizing keratin treatment, you can opt for a formula that contains glyoxylic acid. If you have curly or coily hair and are concerned about formaldehyde (an ingredient that is used to help the keratin penetrate your hair), ask the stylist to use a keratin treatment that has a lower concentration of the chemical or one that is completely free of it.
Keratin treatments are a great option for everyone, including those with wavy, curly, or coily hair. Just make sure to speak with your stylist and find a formula that is appropriate for your hair type and style goals.
3. Avoid Touching Your Hair Throughout the Day
Keratin treatments create semi-permanent results that can last for weeks or months, depending on your hair care routine and the treatment type. They’re an excellent choice for Miami summer hair because they make it easy to achieve a smooth, sleek look that looks beautiful and professional in humid conditions.
While a keratin treatment is great for anyone who struggles with frizz, it can be even more beneficial for those with curls or textured hair. These types of hair tend to absorb more moisture and are more prone to frizz, so a keratin treatment can help keep them smooth and sleek all summer long.
The keratin in a keratin treatment works by sealing and smoothing the hair cuticle, preventing it from absorbing excess moisture. When hair absorbs too much moisture, it can cause the outer layer to lift, resulting in frizzy, unruly hair. By removing this outer layer, a keratin treatment can prevent frizz and make hair easier to style.
To ensure that your keratin treatment delivers the best possible results, it’s important to prepare your hair adequately for your appointment. This includes using a clarifying shampoo to eliminate product buildup and avoiding heavy conditioners. It’s also helpful to moisturize your hair with a hydrating mask or treatment in the days leading up to your appointment.

At McAllister’s, we recommend using products like the Brasil Cacau Hydration Mask to maintain the integrity of your keratin treatment. This deep conditioning mask can help to restore the proper moisture balance in your hair, which will help to reduce frizz and protect your keratin treatment from humidity. You should also consider investing in a humidity-resistant spray, such as the Brasil Cacau Anti-Frizz Serum.
4. Don’t Overstylize styling products
If your hair is very long or has a lot of volume, it may require more styling products than a shorter or more conservative cut. However, excessive use of styling products can cause the outermost layer of your hair strands to become overworked and frizzy. For best results, try to limit the amount of product you use and only apply it to the parts of your look that need it most.
Over-stylizing can cause your hair to be less hydrated and more frizzy because it disrupts the natural structure of your hair strands. It also creates a barrier between your hair and humidity, making it more difficult to absorb moisture from the air. If you must use a styler, opt for a lightweight spray that won’t weigh down your hair or make it appear limp or flat.
Another common causes of frizz is over-washing and a lack of moisture. When your hair is too dry, it can become brittle and more prone to frizz when exposed to humid weather. If you find yourself washing your hair too often, try reducing how frequently you wash it to every 48 hours or less.
Another great way to reduce frizz in humid weather is to keep your locks moisturized with products like whipped shea butter or coconut oil. The oil helps to smooth out the outermost layer of your hair strands, helping to protect against humidity and frizz. If you have very thick or coarse hair, try using a leave-in conditioner or a de-frizzing serum to further enhance your look. For a more permanent solution to frizz, consider getting a keratin treatment, which is a salon service that can last up to six months.
5. Try a Humidity-Resistant Spray To Control Frizz
When it comes to humidity, even a perfectly-styled mane is at risk of losing its shape and turning into a frizzy halo in the blink of an eye. The best way to prevent this is to invest in a good humidity-resistant hairspray. Not only will it protect your style from frizzies, but it can also help your hair retain its natural moisture.
Humidity causes a natural phenomenon known as hygrosis, which is when the moisture in the air absorbs into the hair strands, causing them to swell and shrink. This hydration, along with the heat of the sun and the action of your hairstyle can all affect how your hair behaves in certain conditions. A humidity-resistant spray can prevent this from happening by creating a barrier that keeps the moisture from getting into your strands.
A popular choice amongst celebrities and beauty experts, this coveted spray offers an anti-frizz effect while protecting your style from damage. Formulated with a blend of hair-smoothing amino acids and an anti-static complex, this powerful product can even be used before or after hot tools to prevent dryness and lock in the look you want.
Another effective way to tame frizz in Miami is by investing in a high-quality Keratin Treatment. McAllister’s hair stylists use this revolutionary smoothing therapy to infuse keratin deep into your cuticles, repairing and restoring your hair quality and eliminating up to ninetyfive percent of frizz and curl. This incredibly beneficial treatment is safe for all hair types, textures and colors. It also drastically reduces the amount of time you spend styling your hair and can leave it maintenance-free for months.
