Hello, I have joined the sight on behalf of my mum who has GCA. She was diagnosed in May 2015, started on 80 pred and is now down to 1 but my mums hair has suddenly go very thin and is falling out. She is very distressed about it. Has anyone else experienced this, is it a side effect? How long will it be before it start to get back to normal? If anyone has any answers or suggestions of anything she can do to help this we would be very grateful. Thankyou.
