What's the best way to ask out this girl I met when I was with my neas it her hair dresser.. so a few weeks go by and my neas gos and gets her hair done and this girl askd who was that guy you were with she says my uncle she told my neas he's hot. So how should I go about it keep in mind I'm really shy I'm 28 and she is 25

Go get a hair cut... Request her... Hair dressers love to talk and talk while their giving hair cuts.

Akaetrue just gave you the perfect idea, while your there chatting ask her if she would like to have lunch or dinner with you. You could even invite her to coffee with you at a café. Do ask though before you leave the hair shop.
