I feel that my GHDs are not really doing much these days. They don't feel hot and my hair goes puffy regardless. So I am in the market for a new pair of straighteners. My hair is fine, has a not nice/inconsistent wave to it and a horrible tendency to go puffy/frizzy at the slightest sign of humidity, including just walking into a steamy bathroom for one second!! I'd love to hear your recommendations. Don't know if this is relevant but I am 50 YO, like I said hair is fine, I used to have quite a lot of it but not so much anymore. Please don't suggest I do the curly girl method.
