Wow,you sure have left no stone unturned! It's hectic being a patient isn't it. I see you have a wig service lined up.I bought a very expensive real hair wig,thinking that would be best.I really only wore it a few times cos it was so hot and itchy(hot flushes and summer didn't help).Being real hair meant I had to wash it and then style it again- acrylic wigs hold their style.However,on the upside,it's good to have a wig if you have some special events coming up. When my hair fell out, my scalp was so sensitive and I developed a rash. I found soft cotton bandanas and caps best for me.Have you checked out www.headcovers.org ?-cheap and good! I guess the weight loss is a good thing but maybe tell your doctor.It could be stress - I dropped 2kgs in a weekend when I was first diagnosed with bc. Unfortunately I've put it back on and some. Good luck with all your appointments.
