We have struggled with this for years.  Our attorney says we need to use a lisenced cosmatologist, but I haven't found one who wants to "volunteer" their time.  I will be interested to hear how others have addressed the problem. 

We have a beautician on call who gets paid by the patient at a rate determined by our auxiliary.  They do not pay her, but provide the supplies on the cart that she uses.  They also give her a tip at Christmas time.  The calls requesting her services comes through me.

I do have a hair stylist.  She works three days a week.  We give her the space and she supplies the product.  We get a percentage of her sales.  We have had this service for twenty years.  People call and request a time.  Most of the clients are staff and skilled nursing patients.  We advertise the service in the elevators under monthly schedule of events.
