hey, got my hair cut about half an hour ago by this cute hairdresser, we flirted a lot together but i didnt get her number. Partly because it might have been awkward as there a few people in there and partly because i kind of froze up when i thought about asking her.

Whats the best way to ask her out?

I could go back tomorrow (only 1 min from my house) and just ask.

or i could add her on facebook and do it that way, (however maybe a bit stalkerish as didnt ask for her name, just easily found her facebook when i was on the hairdresser facebook page.

not really got anything to lose, so just wanted to know what approach will give me the best chance.
