"Bouncing the diffuser around and constantly moving it creates frizz," says Dueñas. The best way to dry your hair is to keep the diffuser in place and flip your hair to the section you want to dry.

"Once your hair is completely dry, scrunch it gently with your hands by gathering the hair from the ends to the root gently in your palm," says Colombini. "Then, softly squeeze and open your hand in a gentle compression. Do not rub your fingers together, as this will break up the cast that any product has left on your hair."

Curly, natural hair types, you know the drill. You've endured the constant trial-and-error of testing products and techniques to make your hair look defined and healthy. Not to mention, because your curls or coils tend to be drier than straight hair, frizz is also a challenge. That's where a diffuser can be your best friend.

You might have heard that you should wait until your hair is 80 percent air-dried before applying heat, but this rule doesn't apply when diffusing curly hair. According to Jonathan Colombini, a celebrity hairstylist for L'Oréal Paris, it's best to keep your hair as wet as possible before diffusing to help eliminate frizz. We're talking dripping-wet hair.

We describe a numerical model, based on a Monte Carlo algorithm, to calculate the propagation of polarized waves through highly scattering microstructured materials, and to properly account for the effect of both loss and boundaries. As an example, we investigate the impact of a strongly scattering object of air-polymer composite material on a broadband collimated source. We also calculate the depolarization of linearly polarized and circularly polarized waves escaping from the sample boundaries, especially at large scattering angles, and we show how boundaries can modify the distribution and the polarization of the scattered waves propagating out of the sample.

The exception to this rule is for those with tighter curl patterns. "On textured, tight coils, set your hair where you would like it to live and move the diffuser around your head without touching your hair," says Dueñas. Do this until your hair is completely dry.

To help enhance your curls, Colombini suggests molding them by wrapping them around your index finger, creating tendrils. "This will later be broken up once completely dry," he says.

Touching your hair at any point throughout the diffusing process will make it frizzy. As difficult as it can be to leave your hair alone, it's best to not touch it until it is fully dry. And even then, try not to touch it unless your hair feels crunchy or hard.

While diffusing curly hair is relatively simple, it's also easy to make some common mistakes. Here are the steps you need to take, along with tips stylists recommend.

"Be patient when diffusing your hair," says Colombini. "Low heat and low pressure create a longer styling process, but it's worth it!" Using low heat can help reduce frizz, preserve your curls, and maintain moisture in your hair. Overall, it helps to protect your curls from damage and keep them looking healthier and more defined.

One of the biggest causes of frizzy hair post-diffuser is from using a high heat and pressure setting on your hair dryer. Excessive heat can cause frizz, damage curls, and dry out your hair. Similarly, too much pressure can disrupt the curl pattern, create tangles, and contribute to an overall lack of definition in your curls.

"Tilt your head to the side and back, or upside down and hold the diffuser in one spot as close to your scalp as you can without burning yourself," he says. "Leave the diffuser in that one location until the section is completely dry, then move to the next section."

Apply enough product so that when you scrunch your hair, you can hear a squishy noise. That will indicate your hair is wet and moisturized enough for diffusing.

For starters, prep with your favorite leave-in conditioner. The Ouidad Curl Reboot Nourish and Strength Leave-in Mask is a great leave-in option for curly hair types that will nourish and soften your hair.

If you choose to use one, make sure that you apply the heat protectant after the leave-in conditioner to form a barrier on your hair that shields it from the heat of styling tools.

It's important to use products that offer moisture and control, but it's also a good idea (though not a necessary step) to use a heat protector. Applying a heat protectant before diffusing can help minimize heat damage and keep your curls healthy and shiny.

If you insist on drying your wet hair just a bit, Michael Dueñas, a celebrity hairstylist and consulting creative director, says you can scrunch it a couple of times with a micro-fiber towel to soak up some of the water. But be gentle. "I see some clients roughly drying their hair with a towel and being abrasive with it, which will stretch your curls and create more frizz," he says.
