Never trust anyone with something sharp in their hands... it makes sense to find out who you are dealing with first and what experience they have. You don't want to loose an earlobe or worse leave the salon looking like a man! Seriously, it is a great plan to call first and do the same with wig shopping. Go to the place you feel welcome. It is like asking a shop owner if they serve certain ethnic groups...legally they can't turn you away, but you want the best approximation to the real thing and who is better, the one who wants to do it or the one who has to?
