do everything else first, do your makeup, get dressed and leave your hair as long as you can then it'll be less wet when you start drying it and exposed to the heat for a shorter amount of time.
if you use a paddle brush or a large round brush you will be able to blow dry it straight, meaning you dont need to straighten it afterwards so thats a bit better for it too.
and you should use something on it, my hair dresser says you can use anything - heat protector spray, leave in conditioner, even just a mousse, anything at all on your hair that will protect the hair shaft.
