How to straighten a bob?

Question

so my sister recently got a bob. and her hair is naturally straight/wavy but it only looks good on her when her whole head is straight. so i straightened it and it looks messed. so anyone, (preferably people with a bob) can you tell me how you straighten your hair?

thanks: )

Answer 1

Straighten it like you normally would,

but at the ends flip it in a bit.
