Sweatproof Hair Tips Straight From a Hairstylist, Because, Damn, It's Hot Out

Toth explained that when it's super humid outside and his clients are likely to sweat, he avoids any product with humectants or silicones. "Products with silicone can easily break down with sweat and make your hair extra greasy, so I use a drop of Rene Fris Styling Cream ($19) because it's 100 percent silicone-free," he said.

Toth recommends swapping your usual hydrating products for an oil when it's super hot and humid outside. "Oils can smooth your hair without breaking down from moisture caused by sweat or humidity." He recommends the Essence Absolute by Shu Uemura ($69). "It nourishes the hair, rebalances moisture, and even comes in travel size, which is perfect for the beach or for on-the-go throughout a humid day," he said.

Once you start to sweat, a dry shampoo like the Living Proof Perfect Hair Day (PhD) Dry Shampoo ($24) will become your best friend. For those with darker hair and skin, Toth recommends the Verb Dry Shampoo for Dark Hair ($16). "That way, the color will blend with your hair, and if you sweat a little bit, the color will blend with your skin tone too," Toth said.

If you know you're going to sweat and don't want to ruin your style, Toth recommends creaseless hair ties like the Kitsch 8 Pack Hair Coils ($10) and what he calls the "pineapple" method. "Gather your hair into a ponytail on top of your head, bring it all the way through the hair coil once, and then bring it through the coil again but just halfway — resulting in a faux-bun or pineapple shape," Toth said. "Bringing it up high on top of your head will keep your face-framing tresses natural and full of body."

If you want a supersleek ponytail, a strong-hold gel like the Oribe Rock Hard Gel ($42) is the way to go. "Brush it along the hairline to keep your baby hairs 'snatched' and controlled throughout the day," Toth said.
