The KO:KOU Pro Steam Brush Professional Hair Straighteners (STM1170174) is a steam-infused heated hair brush that straightens and styles hair while helping to reduce frizz and heat damage. It uses steam technology to add moisture as it smooths, has a digital temperature display (up to around 230 °C) for heat control, and includes features like a 360° swivel cord, removable steam cartridge, and automatic shut-off for safer, easier styling. It’s designed to give sleeker, shinier results compared with a basic dry heat straightener.
