FHI Heat detangling brush UNbrush Flex — Pink ultra-flexible, anti-static bristles for gentle, faster knot removal

The UNbrush Flex from FHI Heat updates the classic untangle brush with a bendable cushion base and a spiral array of DuoFlex bristles to reduce pulling and static on wet or dry hair. Lightweight and backless for quick drainage, this detangler is engineered to lower combing force and spread conditioners evenly—so you spend less time fighting tangles and more time styling.

How does the UNbrush Flex make detangling less painful?

The brush’s ultra-flexible cushion adapts to your scalp contours so bristles glide around knots instead of yanking straight through them. Combined with 132 DuoFlex anti-static bristles arranged in a spiral, the result is smoother tension distribution and noticeably gentler strokes.

• Flexible cushion base reduces concentrated tension on strands
• Spiral bristle pattern detangles progressively to avoid sudden pulls
• Anti-static bristles minimize flyaways and friction

Can I use this brush on wet hair or with conditioners?

Yes—UNbrush Flex is designed for wet and dry use and excels when distributing treatments. The bristles help spread conditioner and masks evenly through the lengths, allowing quicker, smoother rinses and more efficient styling afterward.

• Safe for use in the shower during conditioning treatments
• Helps distribute leave-ins and masks for uniform coverage
• Backless vented design drains water for hygienic cleaning

Will it work on thick, curly, or damaged hair?

The brush is made for all hair textures, including thick and curly types, as well as fragile or color-treated hair. It reduces wet combing force significantly, helping prevent breakage and making it easier to manage dense or textured hair without aggressive pulling.

• Reduces wet combing force by up to 57% compared to rigid brushes
• Gentle on color-treated and chemically processed hair
• Effective for both fine strands and coarse, curly textures

How easy is it to clean and carry the UNbrush Flex?

The backless, vented cushion drains quickly and resists trapped moisture, making rinsing and drying fast. Its lightweight build and ergonomic shape fit comfortably in a shower caddy, gym bag, or travel kit for styling on-the-go.

• Backless design prevents water buildup and simplifies rinsing
• Lightweight handle for one-handed styling and travel
• Durable materials built for daily use and professional settings
