I need to replace my old hair straighteners which I mostly use for curling. I already have a tong and mermaid waver but I find using straighteners to curl is quicker than both and give a different curl type. My previous straighteners were coriolis but I dont want those again. GHD and Cloud 9 seem the main options - should I be looking at anything else? Any thoughts of GHD vs Cloud 9 specifically for curling?
