Blow-drying your hair

At the moment I have been straightening it with my GDH's...I know these are good straighteners, but lets be honest heat isn't the best thing for your hair. I was browsing Youtube and the internet and I came across videos and posts about blow-drying your hair straight. I thought it was worth a try and I am hooked!
