Like it or not it is all about perception.
Attitudes about tattoos are changing here in the US, but I really don't think they are changing that quick in the Corporate World. Sure there are folks with high profile positions and pay that have long hair and tattoos, but what percentage are they? I am willing to bet it is not very high. Times may change, but the bottom line is if you are going for a job in a cooperation and you have long hair and/or exposed tattoo(s), you are taking a chance.
