I am not trying to be rude here, but this is why I suggest seeking a professional stylist and spending a few dollars on getting professional hair and makeup, like Dina said. Each to their own, but this is not my preferred look.
Buff mentioned let the physique do the talking, but I feel it is nice to put 'icing on the cake' so to speak.
I am not sure of US amateur judging policies, but I know here and pro level, the bodybuilder girls always do their hair and make-up up really attractively, and it is somewhat expected by the judging panel, maybe it is not said, but it is subconscious.
IMO I would rather see competitors with their hair styled and makeup, as I think it helps promote female bodybuilding, and works againest those stupid stereotypes that we have all heard.
