UNbrush

UNbrush is a line of detangling hair brushes made by the American hair-tool company FHI Heat. The range centres on a vented paddle brush built around what the company calls DuoFlex anti-static bristles, designed to work through knots on wet or dry hair with less pulling and breakage. It became widely known after gaining traction on TikTok, and the brand has leaned on that "viral" framing across its marketing and press coverage.

The product line is active and currently sold, including internationally. FHI Heat, its parent and manufacturer, describes itself as a maker of high-performance styling tools with more than twenty years in the professional hair industry.

UNbrush is produced by FHI Heat, which is named as the manufacturer on the brand's own product pages [1]. FHI Heat presents itself as a company with "over twenty years" of experience creating hair-styling tools [2]. Its founding year is unclear: the business database RocketReach lists 1996, while search-derived business listings give 2003, and FHI Heat's own About page states only that it has operated for more than two decades without naming a year [3][6]. Because the available sources disagree and none of the brand's primary pages state an explicit date, the founding year is treated as unresolved. This date refers to the parent company; the UNbrush product line itself is considerably newer.

The UNbrush collection is built around a single detangling paddle brush offered in several variants. The company markets the Original as suitable for all hair types, the Plus for fine and fragile hair, the Curl for wavy, curly and coily hair, and the Flex for in-shower use, alongside smaller Mini and keychain-sized versions [4]. FHI Heat also produces licensed editions tied to properties such as Barbie, Hello Kitty, Disney and Star Wars.

The design's defining element is its DuoFlex anti-static bristle system. According to FHI Heat, the brush uses flexible bristles that detangle hair while reducing breakage, frizz and pulling [4]. Editorial and brand descriptions put the configuration at 58 long bristles and 47 shorter ones, combined with a backless vented cushion intended to keep the brush lightweight [5]. The company positions the range around affordable, salon-style results for every hair type and texture, summed up in its stated mission to make "salon-worthy results accessible to everyone" [2].

UNbrush has been recognised in several editorial beauty awards. It was named Best Paddle Brush in Allure's Best of Beauty 2025 [7], and it received Byrdie's 2025 award for Best Hair Products Under $35 as well as a place in Shop TODAY's 2025 Beauty Awards [5]. It also appeared in Essence's Best in Beauty Awards for 2024 [7].

Much of the brush's visibility has come from its status as a TikTok-driven product. Outlets including CNN Underscored, BuzzFeed, Refinery29 and StyleCaster have covered it as a viral detangler, frequently framing it as an inexpensive brush popularised through social media and aimed at people with curly, coily or textured hair. A Byrdie senior beauty editor, quoted in FHI Heat's recap of the coverage, wrote that "TikTok convinced me to try the FHI Heat Unbrush, and my curls are thankful I did" [5]. The New York Times' Wirecutter also tested the brush across several hair types.

The UNbrush line is active. FHI Heat continues to market it, with 2025 award wins, ongoing licensed collaborations, and a brand site carrying a 2026 copyright. The brush is distributed across multiple markets.
