The GHD MK4 Flat Iron - or GHD IV Styler, if you prefer - is GHD's most advanced hair straightener yet. The GHD MK4 features a rounder barrel shape designed to create perfect curls and movement, volumizing in a flash. And it includes a DVD to show you how.

But that's not all. This GHD straightener's smart upgrades include Sleep mode, which turns your iron off after 30 minutes of idling; Shiver mode, which shuts the iron off automatically if the room temperature falls below 41 degrees F, preventing internal condensation that can shorten the life of the iron; and Universal Voltage. That's right. Not dual voltage, but universal voltage which adjusts depending on your power supply, making the GHD MK4 your favorite new travel companion.
