I hate going to the hairdresser too - I have someone who comes round every six weeks or so, just to cut it - I wash it first myself.  The trouble is, every time I find a mobile hairdresser I like, after a few months they move on - the last two have given up hairdressing altogether and the one that comes now has just started a new job so I don't know how long she will still come out.
