Does a hot brush damage hair?
A hot brush provides less damage to hairs and is much faster compared to a traditional straightener when used with mostly dry hair. However, use the hot brush only if you already have dry or slightly damp hair, because this tool only generates heat and there's no mechanism for adding moisture to your hair like a diffuser found on other styling tools. It's also worthwhile to invest in a heat protection spray before using any heat styling tools, including a hairdryer.
