Our verdict

A heated straightening brush for anyone who wants smooth hair with more volume than a flat iron gives. It straightens rather than leaving pin-straight, glassy results.

Overview

InStyler builds the Straight Up as a heated brush where ceramic plates surround each bristle, sectioning and straightening as you glide it down. Cool-touch ionic tips guard the scalp while a digital display shows the heat.

Straightening by brushing, without the creases and flatness a flat iron can leave, is the reason to use it. It heats fast and offers a wide temperature range. Results are smoother and fuller rather than sleek and poker straight.

Who it's for

Wavy or frizzy hair that needs quick smoothing on busy mornings suits a heated brush. People with tight curls who want a sleek finish will get more from a flat iron.

Pros and cons

Pros
  • Brushes and straightens in one pass
  • Digital heat display
  • Cool tips protect the scalp
  • Wide heat range for any texture
Cons
  • Less sleek than a flat iron
  • Voltage and auto shutoff not listed

Performance notes

Straightening comes from heated ceramic plates touching hair as the bristles hold tension. Plates around each bristle spread heat evenly, so fewer passes are needed. Lower settings suit fine hair while thick hair needs the upper range.
