Bored with mid-length naturally wavy hair

Ok heres my problem, i have light blonde mid-length hair that is naturally wavy, ive just got it to a reasonable condition after frying it with daily use of my GHD'S and hairdryer.

I have regular once a month visits to my salon for my root touch ups and my hair stylist always straightens my hair, it does look lovely but as ive found out i cant do this on a daily basis with out severely damaging it.

Id love to be able to blow dry my hair straight and get a salon result but when ever i try it just doesn't happen.

I use good hair products and look after my hair as best i can but i just feel stuck between a rock and a hard place because naturally it's neither straight nor curly but somewhere unruly in between.

Id love to achieve a polished sleek look without having to fry my hair with heat styling.
Any tips, suggestions welcome. xx
