12 Best Hair Straightening Brushes That Really Work
These top-rated hair tools will give you smooth, silky hair in no time.
We updated this article in May 2023 to add more information about each featured product, plus added new picks selected by the Good Housekeeping Institute Beauty Lab.
News flash: while flat irons are a great option for sleek, smooth strands, they are not the the only option out there. Hair straightening brushes work as a flat iron and a brush in one to help streamline the smoothing process, detangling as they style. These tools are essentially hot hair brushes, so you can effectively brush and detangle your hair while you straighten it for frizz-free, shiny hair in a single step.
Quick tip: Unlike hair dryer brushes, you should use a hair straightening brush on completely dry hair, and make sure to apply a heat protectant before you get started.
We put many of these tools to the test at the Good Housekeeping Institute Beauty, Health & Sustainability Lab with both consumer and Lab testing. A total of 55 women tested 11 hair straightening brushes (five for each tool) and shared their findings after, rating multiple factors including ease of use, performance and overall satisfaction. In the Lab, experts measured other elements including weight and cord length and more. Keep reading for the best hair straightening brushes which include top picks from our GH Beauty Lab test and highly vetted top sellers online.
