It has been 3 years since my elderly mother let me wash her hair, she keeps it pinned up and it stinks and her head has cacked up oil and debre. She also refuses help with bathing. I'm afraid she will get an infection of the scalp. what can i do, wh do I turn to for help. My mother is very stubborn. What if she gets real sick? Will me and my sister be liable even if we have tried to care for her? what can we do?
