Harriet?

Today I visited Shampoodle and Harriet said "I think you'd look good in a boy's haircut." I've never seen anything on the wiki about this...Do you unlock the ability to get the opposite gender's haircut after having like 10 hairdos? (I said no, since I was looking for a particular girly haircut)

(lol, I can imagine a guy being all "NO, I would not look good in a girls haircut >:C)

Yes, but I'm not sure exactly how many.

I think once you get every haircut of your gender, you unlock the ability to get haircuts from the opposite gender.
I was wrong. You unlock the opposite gender's hair style choice after you get 15 haircuts, courtesy of JVGS.net (http://www.jvgs.net/new-leaf-hair-guide.htm)
