My Mother (94 years old) has had dementia for 9 years and has been at the stage of being aggressive and refusing to do most things. Can anyone offer advice on how to get her to agree to be washed or have her hair washed ? I have bought large body wet wipes which her carers use occasionally but she hasn't let me wash or cut her hair for a LONG time. I tried a shampoo shower cap but she hated it. I just don't seem to know what else to try or say to let me assist her. She seems to not like being touched any more and hates water.
