Do you ever look at a celebrity and think, "how on Earth do they get their hair to look that perfect?" For me (and many, many others), Sydney Sweeney is one such A-lister. And while high-quality extensions, expensive color jobs and luxury styling products are usually the components we associate with those out-of-this-world celebrity manes, one look into the styling kits behind Sweeney's best beauty looks will prove that the real secret to a red-carpet ready 'do is a good hairbrush.

Why Sydney Sweeney's Hairstylists Can't Get Enough of FHI's UNbrush

While the shine-enhancing oils and curl-creating hot tools play a big role in creating an event worthy hairstyle, the foundation of an A-list level 'do is, unsurprisingly, a good-quality hairbrush. At this year's Met Gala, Sweeney appeared on the famous steps rocking an ultra-slicked back bun, and the secret to pulling her lengthy mane into shape was none other than FHI's UNbrush ($18).

The 2025 Met Gala was not the first time Sweeney's glam squad has used the viral detangling brush on her iconic strands. In fact, the snag-proof tool has become a staple in her event-prepping routine thanks to the brush's quick, easy and hair-friendly 105 dual length bristles that make brushing literally painless.
