This is Beth. Reporting on February Dark.
It was dramatic enough to elicit several “I didn’t recognize you”s. That’s as mysterious as I got.
I also heard, “You look like a different person” more than once. It made me think of Billy Joel’s The Stranger.
“They’re the faces [hair] of the stranger but we love to try them on.”
The “You remind me of”s amused me: Charlie’s Angels, Jersey Girl, Bono’s Sister (if he had one), and Madonna in Like a Prayer.
Friends sent me examples of dark hair:
Jewish celebrities (apparently a “type” some find attractive).
And:
Inexplicable.
P.S. Thanks to fabulous February guest bloggers
and baby
P.P.S. Random comb-on-the-street shot for February:
Changing the Locks 
By the end of 2013, think how many combinations of Charlie’s Angels we could make between the two of us!
It is interesting to me that so many folks did not recognize you so well. I usually have a terrible time with face recognition when somebody changes their hair, but I recognized you right away and I think the color suits you well.
