Summer is, for obvious reasons, the season of the air-dry. But, without the right products and techniques, curls can easily turn frizzy and lose their definition.

To keep your texture refined and your style defined, we’ve rounded up a few key tips to help you embrace the heat and enhance your curls.

How Heat & Humidity Impact Your Curls

Sometimes the heat works with you to help dry hair quicker and create a bouncy finish. Sometimes, when paired with humidity, it can work against you leading to frizzy, ill defined curls. When hair is dry and dehydrated—which is common with curly hair textures—it seeks out moisture in the air, which is what causes hair to frizz in humid environments. Because of this, the best way to safeguard your style is by enhancing the health of your hair first with products that provide weightless moisture, cuticle protection and nourishing ingredients.

The Best Products to Air-Dry Curly Hair Types

While curly hair care is essential year-round, during the summer months it’s critical to the success of your style. This is because, when temps spike dry hair can become drier and frizzy hair can become frizzier. Choosing products designed to nourish your hair type—like the CURL Regimen—are key.

Start off your summer curl routine with a shampoo and conditioner created for curls. KILLER.CURLS WASH + KILLER.CURLS RINSE are formulated with Organic Oat Milk—rich in fatty acids—to preserve strength and moisture, and enhance texture and shine. Noticeably improving the health of the hair to cut down on frizz, this is the first step toward defining your curls.

Next, practice your air-dry technique with a styler made specifically for air-drying. KILLER.TWIRLS is an air-dry crème that enhances definition while keeping hair hydrated and protected against humidity. Whether hair is naturally curly or permed, this crème has a unique Refining Complex that smooths and strengthens while enhancing shine to create a perfect finish thats also protected against breakage, flyaways and colour fade.

While KILLER.TWIRLS works beautifully on a variety of curl types and textures, KILLER.WAVES is a great alternative for fine hair types, while EASY.RIDER is great to detail your finished look and protect against frizz.

Air-Dry Techniques to Define Curls

From shower to finished style, every step you take along the way impacts the look of your curls. To encourage more definition and cut down on damage and frizz, stick to these rules.

Invest in a microfiber towel. An old T-shirt works well too. Terry cloth towels can rough up your cuticle and cause friction, which leads to frizz.

Comb in the shower. Prep your hair while you’re already in the shower. Some hair and curl types can get away with combing after, but mostly curly textures perform better when you limit combing and touching as much as possible.

Learn how to layer products. There’s picking the right products, and then there’s layering them properly. You’ll find your own unique rhythm, but stick to a few necessities and make a leave-in conditioner or treatment oil one of them. This improves the health of your hair with every wash.

Don’t be afraid to touch up. While you want the majority of your style to be air-dried, sometimes you might need to touch up with a hot tool. Once the hair is dry, consider smoothing flyaways or enhancing the curves of your curls with a curling tong. This doesn’t need to be all over. Simply touch up areas that didn’t dry to your liking.

FAQ

Curly hair is often drier, so it absorbs moisture from the air. This causes the cuticle to swell, leading to frizz and loss of definition in humid conditions.

Start with KILLER.CURLS WASH + RINSE for moisture, then apply KILLER.TWIRLS to air-dry. This combo hydrates, defines curls and protects against humidity.

Use a microfiber towel, limit touching, and layer products correctly. Applying a curl crème like KILLER.TWIRLS on wet hair helps lock in shape and shine.
