Another revelation, thanks to mumsnet.. My old hair dryer died in smoke, so I decided to bite the bullet and shell out for a parlux, after reading lots of great recommendations on here. (Yes, I make ALL of my life choices and decisions after consulting a parenting forum)
I got the 3800 Eco friendly one and oh my god. It really is amazing! It took half the time to dry and style my hair, I dried it with a round brush and it is so full of volume I look like I've just been to hairdressers. It is so smooth I don't need to run the straighteners through it at all.
Thanks to everyone who recommended it!
