This single tool makes it easy to style your hair with volume, curled ends, or outward flips. It's a cordless, battery-operated type that generates negative ions when switched on. The brush head is detachable, making it easy to clean if you're concerned about hair or dust. It's recommended for those who just brush their hair before going out, or for those who find hair irons difficult to use or are worried about burns.
