Sometimes I do curly and sometimes I do straight. To straighten I have an old pair of Babyliss straighteners and to curl I have a Revlon wand type thing.
I understand that there are gadgets out there that can do both. GHDs seem to be widely advertised.
Can anyone recommend these (or anything else for that matter) for a one tool does both?
It depends on your hair type. GHD straighteners will not make a curl in my (or daughters hair) under any circumstances. If you can borrow some from a friend, do that before paying out.
You can curl using straighteners, I can't explain but I'm sure you could find a demonstration on YouTube. I have owned and used GHD straighteners for over 10 years and wouldn't hesitate to buy again.
