There's no denying that warm weather and humidity can wreak havoc on your locks. The hot and muggy days of August can cause everything from frizzy to poufy hair.

If only we had Reese Witherspoon's insanely smooth tresses!

Well, now you're in luck. TODAY Style spoke with Witherspoon's "mane" man, celebrity hairstylist Cervando Maldonado, to get his best tips for picture-perfect strands all year long.

1. Try mousse.

Whether you wear your hair curly or sleek, mousse will be your new best friend.

For a curly or wavy look, apply mousse to your roots, scrunch the hair and let it air dry. To finish, use a curling iron or wand on a few strands at the top of your head.

For a sleek and straight blowout, apply mousse evenly with a boar bristle brush before drying for a smooth look.

2. Give your hair a break.

Just like you may need time off for your mental well-being, your hair needs a few days off to rest. Let your locks air dry at least once a month to give it a break from constant heat styling. It's easier to damage your hair then you may think.

"Styling hair with a blow dryer or curling iron can be more damaging than coloring," Maldonado told TODAY. "People at home usually don't have the expertise, so they end up burning the hair. That's why you see broken pieces in the front."

3. Invest in a great blow dryer.

While it's often debated, Maldonado believes a great blow dryer is worth the cost, especially for preserving the hair's integrity. To find the best blow dryer, look for the following: a temperature gauge, cool-shot option and ionic properties.

"Air typically shoots out a lot stronger (with a temperature gauge), so it allows your hair to dry faster with less damage. The heat distributes more evenly through the hair," he said.

From Maldonado's experience, professional blow dryers tend to last longer and typically have more generous warranties. He's a fan of small and portable options, so you can take it wherever you go.

4. Use coconut oil.

Yes, that coconut oil sitting in your pantry is also great for your hair. Apply it to the ends of your tresses, wrap it in a bun and head out the door. Otherwise, just put it on for 10 minutes and wash it out.

"It's something easy that everyone can do," said Maldonado about his favorite trick.

If you're worried the oil will leave your hair greasy or your fine strands lifeless, don't fret, Maldonado has an easy fix: Use the treatment and then put shampoo on your hair before heading into the shower to rinse it out.

5. Use multi-purpose products.

Simplify your beauty routine by using products that have more than one use. Maldonado's personal favorite is Sachajuan's Volume Powder. It can be used on the roots for volume and the ends for a piecey look. It's also a dry shampoo and comes in a formula specifically for brunettes, so you can avoid any white residue.

6. Pick the right products for your hair.

For those with curly hair, Maldonado likes curl creams that lock in moisture and fight frizz. Curly hair tends to be naturally dry, so it's important to use a product that moisturizes. The more moisturized the hair is, the less frizzy it will be.

If you want to blow dry your hair straight, he recommends starting with some product to help get hair moisturized and smooth. Then, to tame any of those annoying flyaways, use a clay wax. Take the tiniest bit — less than the size of a pea — rub it in between your hands until it's clear, and smooth it over any frizzy areas.

"It holds everything and doesn't look like anything is in (the hair)," said Maldonado.

7. Take a pass on shampoo.

If you don't have big plans, then pass on shampooing your hair. Shampoo dries out both your ends and scalp. The less you shampoo, the more moisture your hair will retain and the healthier it will look.

"If you can, the least amount of days is every other day," explained Maldonado. He said that typically clients will ask him why their hair is dry, and the answer is because they're shampooing too often.

For an easy in-between-washes hairstyle, Maldonado suggests putting a little dry shampoo through the roots for volume and then pulling the hair back into a sleek ponytail or cool topknot. It will instantly give you a polished look.

8. Fighting frizz starts in the shower.

Maldonado says that the shampoo and conditioner you use may be the culprit of any unwanted frizz.

When picking either product, go for ones that both hydrate and include silicone.

When it comes to conditioner, Maldonado suggests combing it out in the shower to evenly distribute the product.

"The longer you leave it in, the better it will be and the more control you will get out of the product," he said.

Maldonado is also a fan of leave-in conditioners when it comes to combating frizz.

9. Allow your hair to air dry slightly.

If you have straight or wavy hair, don't go immediately for the blow dryer when your hair is sopping wet. Instead, wait until it's mostly dry before applying heat. The one exception is curly hair.

Before you grab the blow dryer, Maldonado suggests combing out each section of the hair to get all of the knots out. He's a fan of using a brush made for extensions.

Once the hair is combed and you apply a heat protectant, you're ready to start blow drying. With the blow dryer, be careful not to press it right on the hair or hold it too close as this can damage it.
