Are you fucking kidding me, is this conversation seriously happening. Get what ever hairstyle you think looks good on you and makes you confident, cause all they give a shit about is your confidence. I am rocking (and I say that word lightly) an almost to be jew fro, with curly ass strands flowing down my cheek. You think that effects my game in any way. Maybe there is a 1% that instantly orgasm when they see my hair and ignore everything else, fuck me silly 100% because of my hair, but I assume that with most people they dont give a shit. Especially since if a girl wants to continue to fuck you, she will tell you... hey faggot cut your hair, you like a fucking mop. Then you will either tell her to suck your dick or take her advice.
So basic answer. No it doesn't matter that much, its all about your confidence. Obviously it doesn't hurt to have some style, since it really does change your look. But dont get an emo look if your a giddy chipmunk all cute and fluffy and shit. Stick to your style/personality.
Entourages, yes you're right if we are talking about this what is the most important, it's inner game. Hairstyle probably doesn't affect your game, but good looks can affect your results. The better you look, the less you talk. You don't need a ferrari or a six pack to fc models, but it's easier when you have them than when you don't. It's good just to look ok and hairstyle is the easiest way to a makeover.
Cheyenne, have this in mind, focus on you game more than on your hair, but use all your feats to close. Changing hair/clothes it's a minimal effort, but can help to achieve better results.
