Both the GHD Platinum+ and the Dyson Corrale sit at the premium end of the straightener market. Both make bold claims about heat technology and hair health. I've used both extensively and I have clear opinions. Here's the honest breakdown.
GHD Platinum+: What It Does Well
The Platinum+'s headline feature is its predictive technology — a smart sensor that monitors heat 250 times per second and maintains a steady 365°F. This single temperature approach is deliberate: GHD's research found that 365°F delivers optimal styling without the cuticle damage that higher temperatures cause. The result is up to 70% more shine compared to non-predictive straighteners — a claim I can corroborate from client results.
The plates are wide and smooth with a gentle curve that works for both straightening and loose waves. Glide is excellent. The tool heats to full temperature in 25 seconds. The drawback: you can't adjust the temperature. If you have very coarse, resistant hair that benefits from higher heat, the Platinum+ may not deliver the straightening power you need.
Dyson Corrale: What It Does Well
The Corrale uses flexible copper manganese plates that reshape to gather hair and deliver more even heat with less pressure. Dyson claims this results in up to 50% less hair damage. The cordless functionality is genuinely useful, and the temperature range (330°F–410°F) gives more control than the GHD's fixed temperature.
The Corrale is lighter than it looks and genuinely comfortable to hold for long sessions. The magnetic charging is elegant and reliable. The drawback: battery life caps at approximately 30 minutes of cordless use — limiting for thick or long hair.
Which Hair Types Should Choose What
- Fine or color-treated hair: GHD Platinum+ — the fixed 365°F prevents accidental over-heating that damages fragile strands
- Coarse, resistant, or thick hair: Dyson Corrale — the higher temperature ceiling handles stubborn textures better
- Frequent travelers: Dyson Corrale — cordless and dual voltage
- Maximum shine priority: GHD Platinum+ — the predictive technology is unmatched here
