Ok, so basically I don't really understand heat protection spray.
I get the concept of wash hair, apply to damp hair then blow dry / heat style as desired. However what about when you're straightening or curling already dry washed hair?!
I wash my hair at night and just let it air dry over the course of the evening and the night. Then come the morning I style it. Normally it's chucked up but now it's getting longer I sometimes use the straighteners and find the ends are starting to look frazzled. I conclude I need heat protection spray. Do I just spray all over the dry hair and then crack on? This seems weird as my hair will be pretty damp and not sure how effective said heat styling will be?
I feel like I'm definitely missing something here... please send help
