answer: patients/clients who are able to overcome their comittment issues.
there are very few women i know that will change their "service provider" once they have identified one that they trust, not necessarily like, but definitely feel "comfortable" with. the professional that is wielding the appropriate metal device will then be followed (sometimes even stalked), with unwavering loyalty, over office or salon moves, health insurance changes, and quite often, state lines. sometimes for decades, and even in spite of retirement.
i went 5 months, FIVE (caps and long hand are necessary to convey the emotional scarring), without going to the hairdresser when i moved to san diego. this is far too long to be walking around with a skunk stripe of dark roots for all to see, but wait and wear hats i did. i could not bring myself to go to another stranger, only to leave in tears, because she didnt do it; "the way KIM did it".
