This hair straightening brush combines the functions of an electric heat brush and a hair straightener, allowing smooth straight styling in a single pass for improved styling efficiency. It uses PTC heating technology with a 3D comb teeth design for even heat distribution, effectively reducing heat damage to hair and creating a smooth, frizz-free finish. Its straightening efficiency outperforms traditional electric heat brushes. The device offers 5-temperature settings suitable for fine, normal, coarse and other hair types, with 20-second fast heating to meet daily quick styling needs. The shell features an anti-scald structure to prevent burns to hands and scalp during use, and automatically shuts off after 30 minutes of inactivity for enhanced safety. It supports wide voltage for use in different regions and is equipped with a 360° swivel power cord for flexible operation. Accessories include a detangling comb, sectioning clips, heat-resistant glove and storage bag, making it convenient to store and carry for home daily care and travel use. Color: Black.
