I couldn't stand it anymore. It is now 3 months since my last hair cut. DB plucked up courage and slowly got on with it. I had to wet it several times!
I got him to take off 1" all over, as best he could. We segment the hair into roughly 1" squares, twist it and trim. It seems to work. Still a bit long but a big improvement which these before and after picutres don't do justice:
Bit of a chunk left at the bottom which I can't normally see. In in 6 weeks (hopefully) my hairdresser will be here to give me a good cut.
Unfortunately for me, I tweeked my back standing up from washing my hair over the bath - the only option we have. I shall probably be out of action for a little while:(
