This Trending Haircut Can Make Your Locks Look 10x Thicker

As much as we wish we could instantly restore lush, full locks, we know that encouraging hair growth does not happen overnight (big sigh).

Even the best hair growth serum or supplement on the market takes time—and consistent use—to deliver desired results. But can you rely on certain hairstyling tricks to make your locks appear twice as thick in the meantime? Oh yes, you can.

"The U-shaped haircut is referring to the shape of the perimeter of the haircut," says celebrity hairstylist Clariss Rubenstein. "Instead of being cut straight across, it is cut in a U-shape which is longer in the back and shorter in the sides and front." So when someone looks at the back of your head, the ends of your hair will follow a U-shaped pattern. "The U-shape has a retro feel and lends itself to the full and fluffy layered cuts that are so popular right now," Rubenstein adds. 

While adding layers can help create that fluffy bounce, you don't have to necessarily shear off any inches: "It can also be one length while the perimeter or 'outline' of the haircut resembles a U," notes celebrity hairstylist Sunnie Brook.

This popular style gives off the illusion of fuller locks, even if you don't wish to chop precious inches—it's a trick of the eye. "It has to do with the curvature of your head," says Brook.

"The back of our heads have the most hair, while the side tends to be less dense and oftentimes the most damaged. By curving up the outer shape of the hair, you're removing dead weight and giving the hair more movement, and this gives the hair more lift and volume from the shape." 

You see, dead, brittle hair appears thinner, and most people tend to have damaged ends around the front and sides of their mane where the strands are more fragile. On the other hand, hair tends to be much stronger and denser in the back, adds Rubenstein.

Here's the thing: The U-shaped haircut may be super buzzy right now, but it's not exactly a groundbreaking idea. Stylists have been fashioning this layered cut for years—it just didn't have a cute name until now. They've long known that trimming off dead ends can create a fuller look, and stylists will tailor the exact length and layers to your face shape.

However, if you'd like to mirror the U-shaped cuts you see taking over social media, feel free to bring photos! "It's a great way to make sure you and your stylist are on the same page," says Rubenstein.

Still, your personal hair texture will determine how layered you'll want to go: "If you have fine hair, you may want to take the length up for this shape," says Brook. "If you have thick, coarse hair, you may want to add layers in the interior to remove weight and bulkiness, creating more movement in the lengths of the curve." 

After you've strutted out of the salon sporting a bouncy, U-shaped style—maintaining the look is a whole other battle. How do you keep your U-shape full and fluffy at home? "I love a great volumizing shampoo and conditioner," says Rubenstein. "There's no better way to prep the hair for this look."

As we've said time and again, a top-notch hairstyle starts in the shower. Specifically, Rubenstein praises the MONAT IR Clinical Thickening Shampoo and Conditioner. "It's a great foundation for a full, bouncy, layered blow-dry," she notes.

If you do choose to blow-dry, a heat protectant is nonnegotiable.
