Hands-On Review & Editor's Verdict
Overview: The GHD Platinum+ 1-Inch Styler is widely regarded by celebrity hairstylists as the gold standard in intelligent heat styling. Rather than scorching hair at 450°F, GHD's research laboratory proved that 365°F (185°C) is the exact glass-transition temperature where hair keratin reshapes without frying internal moisture bonds.
Equipped with Ultra-Zone predictive technology, dual infinity sensors across the precision-milled floating plates monitor heat 250 times every second. As you glide through thick or coarse sections, the iron instantaneously boosts thermal delivery so the plate never drops below 365°F—delivering one-stroke straightening and frizz-free gloss.

Frequently Asked Questions
Why doesn't the GHD Platinum+ have manual temperature buttons?
▾
Hair heated above 365°F suffers irreversible cuticle cracking, while temperatures below 365°F require multiple damaging passes. The Platinum+ automatically adapts power output to maintain exactly 365°F regardless of hair thickness.
Can I use the GHD Platinum+ to curl and wave my hair?
▾
Yes. The rounded outer barrel and wishbone hinge are specifically designed to create ribbon curls, beach waves, and bevelled ends without leaving clamp creases.
Can I take this flat iron to Europe or Asia?
▾
Yes. It features built-in universal voltage that automatically adapts to electrical outlets worldwide with a simple plug adapter.
