There's quite a few articles like that out there that will generally say the same things. It's not always entirely accurate, however. It really depends on your face. And some webpages will say the exact opposite information as others.
I have a square face. They say to avoid center parts - in that article, Jennifer Aniston has one. I have a widow's peak, so a center part actually makes my forehead look smaller and more rounded, rather than broad.
I also look more masculine with my hair down around my face. Mine is chest length and I have to keep it behind my ears, rather than letting it get in my face or it looks blooming awful. One of the best styles I've found for me is a hanging updo that drops down and frames my neck. Face completely exposed, but with a nice pair of earrings and the framing at the neck, surprisingly feminine. I can only imagine how well it would work if I wore makeup.
Something I've been thinking about is how depending on your hair or face, certain cuts seem to completely backfire for a transperson. There are certain 'feminine' cuts that you tend to only really see on young guys going for the long hair look, and certain 'butchy' styles that you only see on lesbians (or at least girls who false positive gaydar everywhere they go.) Even if 'long hair = chick' and 'short hair = dude', people may notice these styles and combine them with our other traits and figure it out.
Not sure if that makes any sense to anyone but me.
