Overview
Brushing through knots on wet or dry hair is what this FHI Heat brush is made for, with DuoFlex anti-static bristles and a vented head. The handle is rubber and lightweight, and the shape is square.
The reason to buy is a detangler that releases knots and reduces breakage on all hair types. The limitation is the missing bristle detail and the lack of any size beyond weight.
Who it's for
A person with thick, curly or easily tangled hair who wants a lightweight everyday brush. Someone who wants a round brush for blow-drying volume should look at another type.
Pros and cons
- Works on wet or dry hair
- Vented to speed drying
- Lightweight rubber handle
- Bristle material not listed
- Not a round styling brush
- Brush head size not given
Performance notes
Flexible bristles bend to release knots instead of pulling, which is how breakage and split ends are reduced. Vents let air and water pass through the head, which helps when brushing wet hair. Anti-static bristles cut flyaways on dry hair.
