Overview
At about 1.5 ounces, the FHI Heat UNbrush is built to be a lightweight detangler, pairing DuoFlex anti-static bristles with a fully vented, backless head for use on wet or dry hair.
FHI Heat leans on two things here: an anti-static bristle coating meant to cut down on the frizz brushing itself can cause, and a backless, fully vented head shape that lets more air and product move through the hair than a solid-backed brush would.
- DuoFlex anti-static bristles
- Ultra-light 1.5 oz handle
- Backless vented cushion design
- Works on wet or dry hair
Who it's for
Works for anyone brushing multiple hair types in one household, since it's marketed across fine, thick and curly textures. Less of a fit for someone who wants a firm, structured bristle feel.
Pros and cons
- Extremely light at about 1.5 ounces
- Anti-static bristles help reduce frizz
- Works across fine, thick and curly hair
- Vented cushion speeds drying and rinses clean
- Backless vented head has less cushioning than a paddle brush
- Flexible bristles feel softer than a firm-bristle brush
Performance notes
The DuoFlex bristles are built to bend around knots instead of catching on them, which is what's meant to reduce the pulling that causes breakage. The backless, vented cushion behind the bristles is the part that speeds drying and makes it easier to rinse hair product out of the brush head.
