Tips for taming frizz

Before my hair was dyed blonde my hair just wouldn't settle.

I have half an hour of sleekness then the humidity etc gets to it and it starts to frizz up.

Its also a hormonal issue because the back of my head fires out the most amount of heat so there's often a wave there.

Anyways... I wash with pantene and use their heat serum with anti frizz but I still have the issue.
