4 Fall Hairstyle Trends You'll Want to Add to Your Rotation

If you're on TikTok, you know the '90s blowout is very popular right now, and that's not changing anytime soon. (So if you're still learning how to create the look on yourself, you have time.)

"This blowout style is all about volume, movement, and layers," Mia Santiago, celebrity hairstylist speaking on behalf of Unite Hair, tells POPSUGAR. "To achieve this look, you want to make the hair as bouncy as possible."

You'll need a round brush to help you get the optimum bounce, plus a good volumizing spray, like the Unite Boosta Volumizing Spray ($29).

Another popular hairstyle trend on social media right now? The sleek knot bun. What you may not realize is this summery updo pairs perfectly with your turtlenecks and scarves in the fall.

"Wearing the hair slicked back and twisted into a chic or funky tight knot is perfect for fall," Santiago says. To really seal in the style, we like the TIGI Bed Head Hair Stick ($20).

For more nostalgia and hair inspo, look back even further than the '90s. "For fall, I will be leaning into fluffy retro curls and all the styles that can evolve from a great curl set, like a '60s mod half-up half-down [look] or a '70s feathered, bouncy curl vibe," says Nikki Nelms, celebrity hairstylist and Goody brand ambassador. "These curls can be easily achieved from a pin-curl set." Regular bobby pins work great for this, but you can also really lean into the retro vibe by using the Goody Go Curl Foam Rollers ($8).

Opposite of the bouncy '90s blowout and fluffy '70s curls, you have soft waves. "Think polished but not perfect waves," Santiago says. "This effortless yet chic look will be around this fall."

You can achieve the look in three different ways: with a hot tool, by putting your hair into a loose braid, or by using an air-dry cream to embrace your natural waves. For the air-dry method, we like the JVN Complete Hydrating Air Dry Hair Cream ($24).
