John Frieda Frizz Ease Heat Defeat Protecting Spray 150ml, Moisturising Hair Spray for Heat Protection and Frizz Prevention

Will it continue to protect my hair from straighteners if applied before blow drying? Styling tip from manufacturer says apply to ends of dry hair??

I used this in blow dried hair which left it damp. then i used straighteners but my hair went all frizzy. what am i doing wrong

can i use this with a curler?

does this work on very fine hair most other products leave my hair really flat and greasy looking after I use them with my flat iron?
