Do This!

Do her hair

Guys, this could be brilliant: You're going out anyway, right? Why not be the one who wields the implements of coif creation? (Think of the gratitude.) For the event BYOB X 3, the three Bs are blow-dryer, bottle, and boyfriend (or beautiful partner). Ladies, the pros will teach your significant other the tricks to blow-drying your hair while you have a glass or two - then it's out on the town (and one of you will at least have a trade if it doesn't work out - but why shouldn't it, given that devoted effort?). It's at Follicle Studio, 741 S. Fourth St. Time: 5:30 to 8:30 p.m. Tickets: $35. Information: 215-564-9099 or folliclestudio.com.
