ANASTROZOLE HAS RUINED MY HAIR

Hello,  I don't normally get involved in chats, etc, but I have looked at how everyone seeems to be helping one another on here so thought I'd chip in.  I was diagnosed with stage 2 oestrogen positive breast cancer in Sept 18.  I had two lumpectomies and the lymph nodes removed on one side.  Followed by chemo and radiotherapy.  My dexa scan showed a little thinning of the bones so so far so good.  Anastrozole symptoms are awful including the seizing up of my thumb on the left hand, and various other fingers to a greater or lesser extent on both  Sometimes I can't straighten them and the pain is awful.  Against all this, the thing that is upsetting me most is my hair.  It was thick and curly before.  It has taken a year for it to grow enough for me to go without a wig.  It's thin and fine and is mostly grey with some black.  (I was a natural auburn).  I have bald patches on either side above the temples and on the crown (looks like male pattern baldness).  I'm sorry if that sounds vain but having been through so much, I just would like to at least go back to having nice hair again.  I feel I have the hair of an 80 year old and I'm early fifties.  Has anyone else been through this?  Any advice?  It's the one thing that is making me consider coming off the tablets.  I don't think I can look like this for another 4-9 years.  Thanks, everyone.
