The GHD Platinum is considered the more advanced tool, with features such as predictive Ultra-zone technology that adjusts the heat to ensure optimal styling. The GHD Gold, on the other hand, is considered a more basic tool with a basic Dual-zone heat sensor. Also, the Platinum delivers salon-quality with ease for even hard-to-manage hair, which the Gold version cannot. Ultimately, the choice will depend on your individual needs and preferences. If you want more advanced technology, the GHD Platinum is surely the better option, but if you are on a budget, the GHD Gold is a decent choice.
