Hair goes curly during the day

[smff]

I have what I guess you could call a "quiff" hairstyle (I'm a guy, just btw), and I style it with styling powder and a hairdryer.

During the day when I'm at school, it gets really curly and wavy, and it looks horrible. I can never get it to stay straight and like the way I styled it. Any tips?

Try using different hair products. Try using mouse when drying your hair and a stronger hairspray

Straighten it?
