You have heard the responses, so its up to you.
Unfortunately, and sometimes unfairly, the first word that spins through a lot of peoples minds when they see someone with dreadlocks is "stoner". Probably not the best first impression and you willbe fighting it from there on in.
There will probably be plenty of other candidates with similar or better abilities than you who won't have that first impression to overcome.
Do you want to take the chance?
