I heard you can blow your hair after it is sprayed. Is it good?

Answer 1

Nah, it's best to use hairspray only after you've finished all of your styling.

It really doesn't make sense to first spray your hair then blowdry it out. All this will do is cause damage to your hair.

If you're looking for hold before you start blowdrying, apply mousse or gel beforehand; not hairspray.
