Unbrush Review Does Viral Tiktok Hair Tool Deliver
December 17, 2025
Many people dread the painful tugging and pulling that comes with brushing tangled hair. The UNbrush, a viral sensation on TikTok, claims to solve this problem effortlessly. But does it live up to the hype? We conducted thorough testing with four individuals of different hair types to uncover the truth behind this internet-famous brush.
The UNbrush exploded in popularity on TikTok last summer, not by chance but through its remarkable detangling capabilities. Videos showing the brush effortlessly smoothing out even the most stubborn knots captivated beauty enthusiasts worldwide. The hashtag #unbrushbrush has accumulated over 4 billion views. The convenience of purchasing directly through TikTok Shop further boosted its sales, with official reports indicating the brush surpassed one million units sold within its first seven months on the platform.
As someone with fine, easily tangled hair, brushing has always been an ordeal. A simple breeze could turn my locks into a knotted mess. Childhood memories of tearful brushing sessions gave way to reluctant tolerance as an adult. While the Wet Brush offered some relief, it didn't eliminate the discomfort entirely.
When UNbrush videos flooded my TikTok feed—each showing people of various hair types brushing with surprising ease—I was skeptical but intrigued. One particular video of a mother gently brushing her daughter's hair convinced me to try it. In October 2023, I purchased the $18 brush and haven't looked back.
The first test came after days of neglected hair. Contrary to my expectations, the UNbrush glided through tangles without any pulling. Unlike with other brushes, I didn't need to grip my roots to minimize discomfort. The experience was consistently pain-free and efficient.
To understand the science behind the UNbrush's effectiveness, we consulted Utah-based hairstylist Sahalie Cindrich, who began using the brush in November 2023 and now recommends it to clients.
Cindrich initially doubted the brush's claims but was impressed after testing it. In her TikTok video (with over 525,000 views), she demonstrated how easily the UNbrush detangled a client's long, frizzy wet hair. She explained several key design features:
- Square brush head with evenly spaced bristles: Allows hair to pass through in straight paths from any angle, preventing wrapping around bristles.
- Traditional oval brushes have a single optimal path: Most people hold brushes at 45-90 degree angles, causing hair to zigzag painfully through bristles and potentially break.
- No ball-tipped bristles: Unlike many brushes, UNbrush's bristles lack rounded ends that can snag hair over time. The mix of 58 long bristles (for detangling) and 47 mini bristles (for smoothing) works gently on knots.
Over eight months of personal use, the UNbrush consistently delivered. To verify its universal appeal, we enlisted three colleagues with different hair types: 3a waves, 3c curls, and a parent managing children's 2c/3a curls. All praised the brush:
- Gentle, fast detangling: Testers found it smoother than other brushes, with less hair left in the bristles afterward.
- Easy-to-clean open-back design: Particularly beneficial for product users, as residue rinses away easily.
- Effective wet or dry: While wet use performed best, the brush worked well on dry hair too—though more time-consuming for curlier textures.
Additional Pros and Cons
Advantages:
- Lightweight (1.6 oz) for comfortable handling
- Over 40 color/pattern options
Drawbacks:
- Premium price ($18 vs. $7-$11 for Wet Brush)
- UNbrush Mini ($14) underperforms the standard version
- Counterfeit products flood the market—buy only authentic FHI Heat brushes
While not the instant miracle some TikTok videos suggest, the UNbrush excels at painless detangling across hair types when used properly. For those seeking to minimize brushing discomfort, it's a worthy investment that delivers on its promises.
